Why Choosing Plastic Gears over Metal Gears

Dongguan plastic molding company offers varieties of plastic gears products to its clients across the world. As plastic gears make the largest commodity in the world of production now. T

he plastic industry making plastic gears is turning the trend upside down. The gears are therefore present in every product of the world. There may hardly be an industry that is not utilizing the benefits of plastic gears.

The gears are used in many shapes and sizes. The reality therefore can be realized by the fact that the production of these gears every year is such a large number that it is impossible to even count. Also, the number of productions is increasing with each passing day.

The world saw a great surge in the demand, in the medical industry, of these gears this year. This happened due to the recent COVID-19 pandemic.

Plastic Gears: More Reliable Than Ever

Dongguan plastic molding company ensures the material qualities and properties of plastic gears. This thus makes plastic gears more durable and reliable than ever before. Plastic gears offer several benefits and advantages in terms of flexibility in design.

The product also offers its ability to operate being a noiseless component. It also takes into account the characteristic of operating without the need for regular lubrication.

Several other benefits include low cost and weight parts, offers greater efficiency and resistance to certain chemicals. These benefits are more promising in plastic gears in comparison to metal gears. The advantages include:

Flexibility in Design

Dongguan plastic molding company offers greater flexibility in designs. This is because plastic gear bears more flexibility than metal gears. Therefore, this flexibility proves to be more advantageous in terms of its affordability.

This means that plastic gears are flexible enough to get any shapes of need. This level of flexibility however is missing or absent in metal gears. Furthermore, other elements of the same functionality often find their place inside these plastic gears. By this, we mean spring and pawls. This helps in the consolidation of the parts as well as helps in reducing the overall cost.

It also reduces weight and complexity. The geometry of plastic gear is more efficient than that of metal. Hence plastic gears are ideal for the creation of complex shapes at the lowest prices. These shapes include internal gears, worm gears, and cluster gears with much less cost than in metals.


Dongguan plastic molding company molds plastic in high volume however at a much lower cost. The cost of production of plastic gears appears to be as less as one-tenth to that of metal gears.

These parts are ready to use molded gears that in comparison to stamped and machined metal parts need no finishing. However, on the other side metal gears need finishing in the last stage. This is called secondary finishing.

The plastic gears usually save 50% to 90% of the cost in the finishing stage. This, therefore, makes plastic gears more economic to produce than metal gears.

Light Weight Gears

Dongguan plastic molding company ensures that lightweight plastic gears. As it is a well-known fact that plastic is much lighter in weight the metal gears. The weight of the plastic gear is less than 20% than metal gears.

However, with this less weight, the plastic even then bears the same amount of strength and power. This, therefore, makes plastic gear much lighter but reliable in weight.

This can be realized scientifically that the specific density of steel metal is 7.85. Whilst the density of plastic in nylon and acetal is close to 1.4.

Noise Reduction Property

Dongguan plastic molding company guarantees noise reduction of plastic gears. This can be realized by the fact that plastic gears run much quieter than metal gears. Well, it all depends upon the application for which the gear is used.

The noise of metal gears is around one or two AGMA numbers higher than plastic gears. The plastic gear is used to deform its teeth that thereby compensate for the noise-producing. This however is missing in metals and metal fails to absorb the impacts.

However, the plastic absorbs the impacts of teeth and thus reduces the noise. This is called the noise dampening property of the plastic. This results in the quieter running of the plastic gear. This thus increases the demand for plastic gear integral for running the material that requires quieter drives. This happens with high tooth shapes along with the use of lubricious and flexible material.

The efficiency of Plastic Gears:

The metal is more prone to friction due to high density, rigidity, and weight. The metal gear bears a high coefficient of friction. However, on the other side, plastic gears are low-weight gears.

This is because the plastic gear carries a low coefficient of friction. This allows less horsepower that allows the waste of heat energy. Split path planetary drives are also a property of plastic gear to lend itself to. This helps the plastic to be efficient in terms of design.

This property for being accurate and efficient becomes achievable only because of the process control mechanism. This allows the plastic to achieve a high level of accuracy with an AGMA quality score of 10.

Final Thoughts and Limitations of Plastic Gears

As we know that plastic gear is lightweight and efficient. This is the reason it is the most demanded product in comparison to metal gear. However, even with this huge demand, the plastic gears are limited due to uncertainty in their response to certain conditions. This thus makes them perform well in some limitations. The limitations are:

  • Low weight withstanding capacity.
  • Thermal expansion and moisture absorption make gears less stable.
  • High cost for developing the tooth form and initial mold dimensions.
  • Chemicals and materials do react negatively to plastic gears.

Scenarios in Which You Can Look For New Plastic Injection Molding Companies

There can be different scenarios in which you may hire new injection molders. For example, your new design product requires state of the art technology, something your current injection molding suppliers do not provide. Some other scenarios include, but not limited to:

  • Your engineer's team has redesigned one of the existing injection molded parts
  • The existing injection molder or company is no more meeting the desired quality requirements
  • You want to move the manufacturing from overseas to your country

Plastic Injection Molding Companies

For whatever reason you want to hire a molding company you must hire the right injection molding company for the process. In this guide, we will help you know how you can look for the best companies around. But before that, let’s have a quick look at what exactly ‘injection molding’ is.

What is Injection Molding?

Injection molding is a very common manufacturing process for plastic part fabrication. Manufacturers develop a broad range of products using injection molding. The products to be molded can vary immensely in their application, size, and complexity. The process of injection molding depends on the use of injection molding machines, mold, and raw plastic material.

Injection molding machines are used to melt plastic, and then the melted plastic is inserted into the mold. The melted plastic finally solidifies and cools in the mold. The produced plastic parts are used for different applications.

Injection Molding Application Areas

The most common applications include their use in the creation of plastic housings. These plastic housings are useful in different products, such as household appliances, automotive dashboards, power tools, and consumer electronics, etc.

The injection molding process is also useful in the production of many items of everyday use. These items may include toothbrushes and even small size plastic toys. There are also several medical devices, such as syringes and valves that are fabricated using injection molding technology.

Choosing the Right Plastic Injection Molding Company

Because you are not going to search for an injection molding company very often, so you must choose it very carefully. To help you choose the right company, here are the most important questions to ask the injection molder before hiring them:

  1. Machine Capabilities and Number of Injection Molding Presses Company Have

Before you hire an injection molding company, ask them about their machine capabilities. Also, ask how many injection molding presses the company has. Ideally, the company should have a huge number of presses that tells you that they can handle more and more projects during the given period. An injection molding machine is measured by its tonnage or pressure. A normal machine should run from 40 - 4000 tons. Large size machines are required to accommodate the larger molds.

However, not every single part will run effectively on the larger machines. Only the molder can recognize the best machine depending on the size and number of parts and also the material. You should make sure that the company has at least 100+ injection mold presses and their machine capacities should be up to 105, and the clamping force needs to be 45-720 tons.

  1. The Team

You should make sure that the company has a really strong and experienced team. All reliable plastic injection molding companies have an in-house tool and design building team comprising of highly professionals and experienced individuals. Their team must be familiar with the latest EDM machine tool equipment so that they can operate them professionally. Ask all such questions before you hire a particular company. This ensures that the process from product concept to its completion will be done with perfection.

  1. What about the Mold Guarantee?

This is a very important question that you must not forget to ask. A manufacturing team that has built your mold from the scratch should offer you the guarantees. They should always be ready to help if there is a need for slight adjustments to the mold or if slight repairs are needed. Typically, the high-quality tools built by top companies, Sz-Changhong, rarely need repairs too often.

  1. Customer Support

It is important to know that who is going to support your project and communicate with you. Ongoing communication is important so you should be aware of the managers who are in charge of your project for runs, etc. You will need to have someone from the company’s side who can regularly be in touch with you to tell you about the project status. Therefore, make sure that the company will provide you the top-quality customer support in a timely manner.

  1. Quality Standards

You also need to know the quality standards that the company follows. Make sure that the company is certified and the certification should be from a recognized auditing company. Therefore, ask the company for their certifications and quality standards they follow.

  1. Maintenance Support

A reliable and credible company should have a consistent and rigorous preventive maintenance plan for the molds used in fabrication in their facilities. So, ask the company whether or not they provide proper maintenance support.

  1. In-House Tooling Capabilities

Tooling is of utmost importance to ensure that cost and quality objectives are met. If the company is having in-house tooling capabilities, then it will offer many advantages including saving your money and time. So, this is another important question that you must ask the company that you are planning to hire.

Two Important Consideration for Fill Rate in Plastic Molding Manufacturing

Two Important Consideration for Fill Rate in Plastic Molding Manufacturing

Dec 21, 2020

Fill Rate in Plastic Molding Manufacturing

Improper fill rate and too narrowed gates in the plastic injection molding process result in defective parts both in terms of aesthetics and overall strength. Plastic molding manufacturing involves many procedural considerations. These are important in terms of plastic injection molding.

During the production phase there 4 basic processes that affect the overall quality of the plastic. But amongst them, two considerations are most important that may affect the final molded parts.

You May Also Read: Plastic Molding Manufacturing Tips for Medical Industry

These are Injection molding speed (Filling speed) and Molding gates. The first step in injection molding is the filling rate. The filling rate is the speed by which the molten risen enters the molds. If the speed of the filling rate is too fast or too slow it causes defects in final molded parts.

However, an optimal filling rate makes parts of high quality. Similarly, the size of the mold’s gates is of similar importance. Narrow gates make the filling part more complex. It causes surface blemishes. However, the size of the gate depends upon the resin and the size of the mold.

plastic molding manufacturing
The robotics arm carry the plastic parts away from the injection machine between operation. The hi-technology plastic injection machine automatic operation with robotics system control.

Injection Speed or Filling Rate:

Almost all of the plastic molding manufacturing involves a filling rate process. The manufacturer monitors this process through automated control panels.  Through this control panel, the manufacturer alters the filling rate of the injection process. This is because the filling rate is one of the major processes of injection molding. It affects the directional properties as well as the overall finish of the final molded parts. Hence, by controlling the filling rate, the manufacturer can enhance the quality and mitigate the defects as well. Furthermore, the manufacturer can also solve the molding defects as jetting and burn marks on the plastic surface. Not only this, the filling rate helps in reducing the chances of welding lines that appear on the finished products.

Importance of Molecular Orientation in Filling Rate:

In plastic molding manufacturing, plastic flows in a mold. This happens in a linear motion. This causes the molecules of the resin to orient in a line-up. Resin molecules line up in the direction of flow. The process is called molecular orientation. This happens only when the filling rate is set at an optimum speed. This means that the rate must be fast enough to line up the molecule. If the molecular orientation remains orientated during the whole process, the final product will be stronger. However, in slow orientation, the product remains defective both in strength as well as aesthetics. Disorientation causes cracks that appear on the surface of the final products. These defects are hence also called crazing. The crazing shows up on the surface as a tiny crack line. These lines don’t appear on appearing instantly. Instead, they appear days, weeks, or even take months.

Effects of Poor Fill Rate:

The two most prominent defects happen due to poor filling rate. These are burn marks and jetting.


Jetting also means the worm tracks. These lines thus appear on the plastic surface. Briefly, the jetting occurs when a poor flow rate allows the molten to risen to shoot faster in the molded cavity. On the contrary, a perfect flow rate allows the molten to risen to flow smoothly in the mold to form shaped plastic.

Burn Marks:

The fats injection speed causes the risen to fail to let the air bubble escape from the molten plastic. These trapped air bubbles thus ignite again automatically that appear on the surface. This happens due to the extremely fast filling rate.

Importance of Molding Gates in Plastic Manufacturing:

If the gates of the molds are large, this allows the molten to risen to flow easily and uniformly in the mold. Therefore, it becomes easier for the manufacturer in plastic molding manufacturing to produce high-quality parts. Though by using a small gate the appearance and aesthetic of the molded plastic are good. However, this requires a lot of time for the risen to settle in. Furthermore, this also needs high pressure to force the risen to settle in the mold. High pressure consequently requires extra energy. This, therefore, becomes a costly process. Similarly, a small gate also causes the creation of mold warps on the surface. Nevertheless, large gates allow faster processing hence eliminating the chance of blemishes and black streaks on the surface of the molded plastic. A few factors will help in understanding the role of gates as Size, Number, and Location of Gates.

Size of the Gate:

Size of the gate the time of measurement between two processes in plastic molding manufacturing. These are the filling rate rose and the running time of risen to settle in the mold during the process cycle. Time in the process is the key to make quality parts. This means the risen must reach all the areas in the mold before it starts getting harder. Small gates thus allow the risen to take more time and high pressure. This however makes the part to be stressful.

Location of the Gate:

This problem is associated with the above issue.  Location directly concerns the size of the molding gates. The ideal scenario, therefore, is the right placement of mold in the process. The must lie in the deepest cross-section. This hence allows the risen to flow easily in the mold. The easy and fast glow allows the molded part to be perfect with any sinking and air voids. Similarly, the placement of the gate must not create stress and distortion. This may happen due to poor running of the risen, which resultantly cause the part to be less aesthetic. Hence, the optimum placement and location of the gates stand as the bottleneck of the injection process.

Number of Gates:

For all the two above issues, this step helps in solving them to a greater extent. This is especially a recommendation for the processes that involve dealing with larger molded parts. Hence, this means for larger molded parts, one gate would not be sufficient. Therefore, this calls for the installation of multiple gates. This thus helps in reducing the gate sizes. It also helps in dealing with the small places of the large parts. The places act as the core sections of the aesthetics.

plastic injection molding parts

Common Designs for Molding Gates in Plastic Molding Manufacturing

For a trimmed and aesthetic plastic parts, these three molding gate designs are the best option to choose from. However, their location and finished product are different from each other.

Edge Gates: The edge gates are set up at the edge of the mold.

Hot Tip Gates: These are set up at the top of the molded parts.

Sub Gates: These gates are submarine gate that helps in reducing scars and hence reducing the cost.

Final Thoughts:

This implies that two factors are pertinent for plastic injection manufacturing. The flow rate process must be optimum to make strengthened and aesthetic parts. The absence of which may cause blemishes and shrink marks. Whilst the gates; their size, number, and location also play an integral role in the injection molding process. Poor placement and illegitimate size cause the parts to become harder and warpage.

There are several advantages you get after you hire your injection molding production to a third party. These benefits include:

Outsourcing the Infrastructure:

The initial investment for setting up a production unit requires a pot of money. This is because the size of the unit and machinery requires space and investment.

The huge cost of the machinery is due to the fact it is a constant running design. The build-up of machinery is set up against its regular running of millions of cycles a day. However, for manufacturers who want to run their operation for limited and smaller productions, it costs much.

The intermittent operation and the attached cost go way above the possible profit. On the contrary, outsourcing Plastic injection molding service brings significant benefits. This is because in outsourcing a manufacturer is making a profit on someone else’s revenue.

Therefore, this allows the OEMs to bring in home profit. OEMs can spend this revenue on marketing and innovation.

Professional Guarantee of Expertise:

For an OEM, the production of plastic injection molding parts may not be a core competency. This is because, for most of the manufacturers, production usually is also the phase of learning and training.

The job hence doesn’t become a core competency. Hence it becomes a learning and experimenting phase. This phase, therefore, brings liabilities. Consequently, this production phase requires double the revenue.

One part of the production phase and the other for bearing the training part. Rejection of production parts due to production errors thus directly hits your financial structure. This is just the one defect, not to mention the loss of time.

However, outsourcing Plastic injection molding service guarantees expert production by professional engineers and manufacturers. This saves a lot of cash, time, and burden in terms of learning, training, and experimenting.

Quality Production:

Injection molding production from experts thus brings quality in production. It doesn’t matter if someone is working in injection molding as a prototype partner or a producer.

The outsourcing of Plastic injection molding service hence by expertise ensures quality in all respects. Therefore, this encourages the OEMs to brood over outsourcing as worth an investment. Usually, almost all the major outsourcing units ensure quality production through various certifications.

These include ISO certification, FDA Certification, FFL Certification, ITAR Certification. Furthermore, the decoupled manufacturing process offer by outsourcing production provides quality production. The quality, therefore, retains in every step.

It starts from production to filling, packing, and holding each product using scientific methods. This however is not possible in in-house production. This is because in naïve production fill speed, temperature, and pressure effects quality in several ways.

Innovation in Design and Manufacturing:

Molding production doesn’t mean simply knowing how to produce parts or operating the machinery. Though the production of molding parts seems a simple phenomenon.

But upon due diligence, there are many ways by which the production saves you a pot of cash. It also permits you to be efficient in production and thus enhancing the quality. Therefore, the outsourcing of Plastic injection molding service hence guides and assists you better in producing quality parts.

This also ensures efficiency in design and manufacturing which is not possible with self-production. The effectiveness covers the following areas:

  • Designing and manufacturing affect the flow rate i.e., quality in terms of corners and uniformity in walls.
  • This step also improves the uniformity of cooling time.
  • It also helps in assisting material selection such as gussets and ribs instead of solid walls to increase strength and efficiency.

Cost Benefits:

All the above-mentioned advantages, in the end, affect the overall cost of the production. Directly or indirectly, it affects the most important consideration which is revenue.

This is because cost liabilities may come in many ways. This, therefore, affects the overall operations in terms of time, energy, production errors, and poor Return on investment. However, outsourcing can save you a lot of costs.

The foremost consideration in injection molding the design of plastic injection molding parts. This component is hence integral for the production of high-quality materials. The injection molding, therefore, ensures that a good mold must possess the production of a large number of parts. The high production of parts hence must follow efficiency and consistency.

The high-quality mold ensures the production of parts in a large number. This happens in producing the parts for the first time. This hence eliminates the chances of wastage of time and material as well. However, this requires experience in producing custom parts even in a challenging environment.

This includes the inclusion of state-of-the-art technology that works on using CAD and CAM software. Also, the perfect parts of producing companies consider a consultation with their customer. This is essential for the consideration of each part; its dimension and the quality of the material.

These elements hence ensure that the product must be rigid and hard enough to withstand certain elements. These include the external and internal environmental elements as temperature, pressure, and material.

The manufacturer hence makes sure that important considerations in the mold must be kept in mind. This thus ensures that the injection process works correctly. The consideration of molds includes the thickness of the mold walls. It also considers rib designs, the boss designs, the transition of the corner. Furthermore, these elements also take into account the welding lines of the injection molds. The placement of gates and vents also counts in acquiring the perfect plastic injection molding parts. These elements combine works well to obtain the ideal custom molded parts. After the creation of the mold design, there runs a DFM (design manufacturability analysis). This analysis thus ensures the mold design delivers the expected results.

Designing Manufacturing Tools and Testing for Plastic Injection Molding Parts

For acquiring the perfect plastic injection molding parts, the presence of perfect mold is a compulsion. Without a perfect mold, there is no chance of getting the perfect part. This, therefore, requires the production of high-quality toolmaking consideration.

This step is important because the process of tool making is a time taking process. Therefore, by taking time, this must follow the optimum accuracy in production. This step hence is the most sustainable and substantial element in terms of investment for a manufacturing company.

However, it is not about the cost. But it is about the critical importance of tools in the success of the industry. Large injection molding projects ensure the follow up of high quality, long-lasting precision molds.

For a perfect tool making process, certain factors play an integral role that includes:

  • Firm designing and engineering of tools.
  • The injection mold possesses high-quality stainless-steel material that ensures optimal quality, performance, and durability during operation.
  • The use of high-quality and state of the art tools for manufacturing the precise machinery.
  • Manufacturing projects must follow strict quality standards and tight tolerance in products.

Features of Tool Designing

It is an understood phenomenon that in injection molding, the quality of mold plays a central role.  It takes a significant amount of investment for any manufacturing firm. Therefore, in an attempt to maximize the ROI in any injection molding project, there are certain elements. These features ensure the availability of maximum profit and yield. They are:

The core of the Metal:

For a perfect mold, the core of the metal must therefore be a stainless-steel material at the core. This is because this metal withstands, for centuries the high temperature and pressure. This happens in long production runs that however, still meets the close tolerance.

Number of Cavities:

The highest level of productivity is due to the presence of a high number of cavities in the mold. This means that a high cavity mold product possesses a highly complex matter. The maximum number of cavities thus ensures the maximum productivity in injection molding.

The Mold Base:

 The base makes an integral element in the injection molding. The unit base holds all the major components of the injection mold. This includes cavities of the mold, insert elements, and basic components together.

It also depends upon the size as well as the type of base. Thus, generally, stainless-steel is ideal for producing base. This makes the base capable of making a necessary level of customization.

Machine Design:

This includes the careful customization of molds in the project. This requires careful consideration of the placement of cores, cooling lines, ejectors, cavities, and other such components.

The complexity of the Parts:

For determining the cost of the mold, it is pertinent to consider how complex the mold is. the complexity covers every aspect from the surface to the final part. This also includes the number of cuts and undercuts it requires.

Selection of the Plastic Resin

For acquiring the best quality plastic injection molding parts, the selection of the right material as the resin is critical. It ensures the overall success of the molding process. For this purpose, science makes the selection easier.

The development of polymer science makes it easy for the manufacturer to have a comprehensive assortment. This means that there are a wide variety and choice of selection of resins. This variety allows the manufacturer to feel at ease while choosing the desired quality.

Also, it makes it easier for them to select and alter the strength, and durability of the plastic parts. This is because for each type of resin there are several associated applications.

Production and Quality:

After the selection of molds and resin, next comes the production of plastic injection molding parts. There are several cutting-edge pressers in injection molding.

These edges possess and characterize the variable capabilities and options. The use of the machines surely depends upon the size of the mold. This also takes into account the number of cavities as well as the selected type of resin.

However, some advanced injection molding production units takes special consideration. At this level, they run the sample runs. This sample run ensures the absence of any kind of risk or defects.

Mold on Plastic Prevention and Removal

Plastics are resilient, but mold on plastic is not too far behind. Mold on plastic only needs a handful of conditions to thrive. And once there, it will start digesting additives on the plastic and then get to consuming plastic resins thus effectively destroying your precious plastic belongings.

Moreover, mold is harmful to human health. It can lead to several allergic reactions and acute diseases. Therefore, people prefer getting mold remediation as soon as they start seeing symptoms of mold growth.

You May Also Read: A Comprehensive Guide on Precision Molded Plastics

In this article, we discuss some instruments that can prevent the growth of mold on plastic by tackling spores, (mold’s seeds) and some procedures that can help you remove mold.

Mold on Plastic

Mold on Plastic Removal and Prevention

The key to fighting mold on plastic is prevention. It is best if you take steps to never let it conquer your plastic in the first place. However, if the growth of mold on plastic does occur, there are ways to remove them.

But it can always come back if you do not take steps to nip the issue in the bud and get rid of the root causes of mold. Below we discuss some effective equipment that commercial mold remediation services use for the removal of mold and for ensuring that it doesn’t grow back.

Mold on Plastic Prevention

You can prevent the growth of mold on plastics by ensuring that the plastics are kept in well-ventilated rooms that are not humid and ensure that the temperatures do not become habitable for its growth.

moreover, getting rid of spores is imperative because unless you don't get rid of spores, they will settle back on the surface and trigger mold growth.

Air Particle Counter

Mold, once grows, does not only stick to the surface it occupies. It reproduces by generating microparticles called spores. These spores are air-borne and can travel wherever the wind blows and the air goes.

So, even if you remove the mold from the surface but don’t take care of the air-borne spores, they will settle back on plastics and trigger mold on plastic growth all over again. Therefore, to effectively take care of the mold problem, you must get rid of the spores as well.

But, how can one get rid of the spores if they are so tiny, almost invisible? Well, there are somethings that you don’t necessarily have to see to get rid of them.

An air particle counter is specifically designed to enumerate the number of contaminating particles in the air. In this way, you can use an air particle counter to estimate the concentration of contaminants in the air in the moldy area and prepare to attack not only mold but spores as well to make sure that it doesn’t grow back.

Negative Air Machine

A negative air machine is more of an anti-spore device rather than an anti-mold device. But, anti-spore translates into anti-mold, so it is just as effective.

As we said earlier, prevention is the key when fighting mold, and a negative air machine prevents the mold on plastic from growing back by filtering spores from the ambient air.

Negative air machine utilizes High-efficiency particulate air (HEPA) filters. HEPA filters are known to remove more than 99% of 0.3 micrometer-sized particles. A spore particle size ranges from 4-20 micrometer, thus a negative air machine with HEPA filters can very easily remove spores.

And once spores are removed, all your mold on plastic removal efforts turn fruitful because once removed and kept in a spore-free environment, mold will not grow back on plastic again.


We all have dehumidifiers, but we largely use them for air chilling. However, air dehumidifiers are also very effective in preventing the growth of mold on plastic. Because mold needs a warm and moist environment to grow. And air dehumidifiers work to remove moisture from the air by cooling it down.

Therefore, dehumidifiers by barring the environment from becoming habitable for the growth of mold on plastic, prove to be extremely effective in the prevention of mold buildup and ensure optimum human health.

Mold on Plastic Removal

Up till this point, we have been stressing mold prevention and discussing instruments to prevent mold on plastic growth or regrowth because prevention of mold is inherently removal of mold. However, in some cases, you simply cannot stop mold from growing on your plastic tools or furniture.

So, considering that mold has taken over your plastic commodities, we present you with some effective solutions for removing mold after it has grown.

Ozone Generators

The Ozone generators are one of the instruments you can use to get rid of mold on plastic. Ozone is a gas that contains 3 oxygen molecules. It has one oxygen molecule loosely bonded with the naturally occurring diatomic oxygen. When generators use ozone for mold removal, this loosely bonded molecule oxidizes the mold and decomposes it.

However, ozone is not only effective for removing mold, it can kill you as well. Thus, ozone is only used in sealed places to prevent human casualties and fatalities.

Hydroxyl Radicals Generators

Hydroxyl is an unstable compound that also works by oxidizing and stabilizing mold thus causing it to decompose and die. Furthermore, it is not lethal for humans like ozone is. So you can use a hydroxyl generator for removing mold on plastic without having to seal your home or office.

However, you must ensure that your hydroxyl generator is only producing hydroxyl as some generators while producing hydroxyl also generate ozone in minute quantities. And ozone, even in minute quantities is harmful.

Hydrogen Peroxide Spray

Hydrogen peroxide is an effective chemical for removing mold on plastic. It does not only remove mold but also disinfects plastics and kills any viruses and bacteria that may be present on them.

All you have to do to kill mold on plastic is to use a 3% hydrogen peroxide solution. Pour the chemical disinfectant into a spray bottle and saturate the moldy area with it. Leave the plastic piece saturated with it for ten to fifteen minutes and scrub the plastic clean after it.

Make sure you don’t use a solution that’s more than 10% concentrated. Also, keep in mind that H2O2 may have a bleaching effect so you may want to keep it away from your plastics if you like their color.

Mold is a type of fungus. Warm temperature and humid environment make for the best habitat for mold on plastic to grow. You must prevent mold on plastics to grow or remove them as soon as you can because they may have adverse health effects.

No matter how many times you remove mold on plastic, if you do not get rid of spores, mold will always come back. So the most efficient mold on plastic removal procedure is to take care of spores. Several devices determine the number of airborne spores and filter them out of air.

To remove mold on plastics you have several options. You can either use industrial-scale ozone or hydroxyl generators or you can just turn to your kitchen cabinet and remove the mold on plastics using chemicals like hydrogen peroxide, vinegar, or even baking soda solution.

Everything That You Need To Know About Precision Molded Plastics

As precision molding is expensive and sophisticated, hence, the process is favorable only for the production of complex, small, and infrequent objects. Precision molded plastics are the latest technology for producing plastic parts in the world. As the process involves precision, that ultimately demands sophistication in the process. This characteristic hence demands the process to be expensive.

Therefore, it is not advisable for the production of whole plastic products. Conversely, the process is economical only for the production of small and complex parts. This happens only when there is a need for unusual precision in the development of the product.

You May Also Read: How to Make Plastic Molds Process Efficient using ERP System?

Therefore, being a complex and precise process, it involves the inclusion of highly technical molds. Consequently, the technical molds hence run only of highly technical precision machines.

Since it differs from conventional molding machines to a greater extent. The process develops highly complex and geometrical parts or products. The precision parts replace the high precise metal in industries.

precision molded plastics

How does Precision Molding work?

The world is becoming a complex web of objects that we use daily. Some of these products are highly complex and detailed objects. With the growth in industry and precision molded plastics, the world is also getting familiar with precise shapes.

Now there is a great demand for precise plastic parts that form the majority of the industries. Plastic molds are required in industries of specific shapes that are more convenient and economic than metal. For that reason, precision molding is an apple of the eye for many industries.

This includes the Automotive Sector, the Pharmaceutical industry, Medical Supplies, Information and Business Technology, and alike.

What is CNC Machining?

The precision molded plastics involves the automated production of plastic parts. This happens only with the use of CNC machines. Also called the computer numeric control machines as CNC milling. CNC is a process that allows the automation of the process and tools by using precision programmed software. The CNC machining system comes to the surface in the 1960s. However, the process is still taking the lead even today.

CNC machining is the most preferable method of plastic production. This is because the process allows the production of highly complex and detailed objects with high accuracy. Tools and machines like lathes, grinder, mills, and router are the components that are manageable through the CNC system. The making of molded plastic by CNC system into complex geometric shapes is known as Polymer Optics.

Automatic Potential Process:

The precision molded plastics is the process that is famous for its potential for being an automated process. This means that the process is an automatic process that requires complete computer functioning aspects. Hence, every aspect of the process runs through an automated handling system.

This, therefore, involves fluid and customization of the manufacturing cells and units. Furthermore, the process of precision molding and the related design engineering demand functioning through cells. These cells hence are the backbone of the process and also serve in molding, coating, testing, and packaging.

However, all this process never uses a single manual procedure. Everything follows the automated process line up. Also, the mechanical aspects of the process are easy and customizable. This means that the installation and replacement of any mechanical component of the system is a handy task. This involves mounting lenses, snappers, and other fixtures.

Specification of the Surface:

Despite the number of advantages and edges in the production of precision molded plastics. However, some elements make the process to stay limited to an extent. There is a certain number of limitations that limit the process due to manufacturing technology. The precision molding process works at a certain length. This means that the polymer optical components work only at the diameter from 1mm to 100mm. Similarly, the polymer optical component allows the lens thickness of 1mm to 30mm. Furthermore, the thickness ratio is 1:1 to 5:1.

Important Considerations:

While opting for the system of precision of molding for your production system there are certain considerations. These include the points you must keep and understand at the first hand. These are areas of precision that can help the manufacturer to be accurate and professional.

Tolerance Issue:

As mentioned earlier that precision molded plastics doesn’t take into account the whole production of the plastic parts. However, the process only accommodates the production of units of the parts that require scientific molding techniques.

This means that the process is favorable where there requires the production of high tolerant parts. Since high tolerant parts mean that the production requires the manufacturing of parts in a precise and accurate manner.

The absence of which will cause the product or parts to break and fracture in the molder. Furthermore, sometimes the breaking of certain parts of the machinery while CNC machines still move brings danger.

Material Issues:

The conventional molding injection requires the use of specific materials for production. However, in precision molding plastic, the use of raw or production material differs from conventional molding production.

This involves taking care of the production phase inefficient manner. Therefore, sometimes what happens that in the production phase, the product happens to face shrinkage. For the products in precision molding that bear high shrinkage capacity.

The high shrinking capacity of material causes the shrinking of the product. Hence this makes the product more fragile and therefore ruins the whole product. For this purpose, in precision molding, the use of plastic resin ensures the production of high-quality plastics.

Technique Issues:

For high production phases, where the manufacturer requires to produce material in large quantity, the process requires precision and accuracy. This thus asks the manufacturer to produce identical items with the same accuracy and manner.

If the production of the product doesn’t produce identical items, thus precision molding will not be accurate. This mostly happens in conventional molding processes, However, in precision injection molding, there is no change in the product design. Furthermore, the precision molding process is a slow and steady phenomenon. This thus requires time, focus, and energy.

However, some companies offer rapid molding tooling. But this is not a standard process. The main idea behind the precise injection molding is that it must cover all the basic requirements.

Application of the Precision Molding Process:

The precision molding process involves the production of high-quality material. Precision molding helps in the making of complex plastic parts for various industries. However, the process revolutionizes the production and development of lenses. These lenses are beneficial for various applications. This is because the process involves the production of glass lenses that are much cheaper and tougher than conventional.

Precision molding largely, thus, involves the production of glass material. This includes lenses which are highly delicate materials. It is a harder and expensive product.  However, plastic optics using precision molding changes the world of plastic upside down.

Final Thoughts on Precision Molded Plastics

Precision molded plastics are famous and desirable for the production of complex mass plastic. It involves the production of precise material that is spherical, aspherical, freeform, and diffractive in shapes. This also involves the production of other such types of materials that require high-quality material. This is because it involves perfect optical finishing on the product.

The process, prima facie, looks like a simple method with not much organization. This happens only before you start running the process yourself. However, for large-scale production, the ERP software is integral to injection molding. This is because ERP helps the manufacturer in managing the production assets as well as to increase the yield.

The software also helps in tracking the inventory and ensuring quality control as well.

how to make plastic molds

What is ERP Software System?

Before going into the details of how to make plastic molds using ERP, it is imperative to know what ERP. ERP Stands for Enterprise Resource Planning software that helps in managing the managerial issues of production.

Hence it manages and tracks the inventory records, quality control and also schedules the production phases. With the rise in its demand, the software also happens to grow in many versions. Therefore, nowadays, ERP offers multiple versions. It is available in the cloud system as well as IOS/Android version.

This veracity thus helps the management and staff to monitor the system across the organization. However, choosing ERP software for your manufacturing unit must ensure some pertinent elements. The foremost thing to make sure of is that your software must be flexible and dynamic.

Therefore, it must take into account the futuristic perspective also. It should not rather work only for an immediate future.

Types of ERP software in Injection Molding:

Well, it depends upon the size of the operation. ERP offers three varieties of software for varying sizes of industrial operations. Some of which are:

  • WinMan ERP Solution: WinMan ERP software largely benefits the large industrial production units of injection molding. WinMan offers an enterprise solution to large companies. This software allows a variety of services starting from managing supply chain operations to managing warehouses.
  • Exact Max ERP Solution: Exact Max is an ideal system of operation for SMEs or small growing industrial units. The software solution provides multiple benefits with smart integration. QuickBooks is one of the services of Exact Max. This ensures the streamlining of every industrial process.
  • Visibility ERP Solution: The following is the most complex system of ERP software. This should be an ideal choice for complex injection molding units. This is because it not offers resource planning but also helps in futuristic perspectives.

How ERP helps in plastic injection molding:

Now, let’s look at how to make plastic molds by ERP software. The primary concern in plastic injection molding the management of the inventory. ERP, therefore, helps in managing the inventory from initiation to the termination of the process. The software hence doesn’t only help in dealing with production schedule tasks.

It will therefore also take into account the process of waste management and production efficiency. The ERP also guides the manufacturers in managing and tracking the consumption of the raw material.

This thus benefits the manufacturers in reducing the left it scraps after the production cycle. This way manufacturers can also make sure to reuse the waste material in the next phase.

Quality Control:

Furthermore, the injection molding industry now grows to one of the most innovative industries in the world. This hence asks for monitoring the quality control process for each operation.

The quality operation helps in following the SOPs of operations. As in the case of medical technology, the molding parts must follow the hygiene patterns. To make sure the equipment and instrument must follow the compliant. Quality control ensures the follow up of strict routine on every cost.

Therefore, ERP software helps in maintaining the SOPs by centralizing the process. This centralization guarantees robust management.

Inventory Management:

Last but not the least, ERP software guides the management on how to increase the production yield and productivity. The software thus manages the vast inventory of the molding material that the manufacturers will inevitably use.

What happens most of the time is that the inventory of prototypes usually goes unmanaged. So, to manage the catalog and avoid the iterations of prototype ERP plays an important task. These steps using ERP proves the systematic structure of the company as a professional.

ERP: A complete Solution Guide for Your Injection Molding

ERP software is a complete guide to how to make plastic molds innovative and productive. The molding injection industry offers a wide range of plastic products and parts. These parts serve a variety of industries and services.

With varying purposes, variety, and uses, molding injection possesses a variety of production processes. The variety of operations and processes thus calls for a robust system of software infrastructure.

The software hence helps all the injection molding units to manage their scheduling and capacity building. The number of benefits that ERP offers are encouraging and productive.

Digitalization of Industrial Process:

Digital technology in any form revolves and shapes our lives every day. Not only personal life but also the business structure across the globe turns digital in every aspect. In this era, just participating in digitalization is not a solution for survival.

However, Expanding and reshaping it is the key to success. The real change and development happen when we manage the business and industrial operations using the software.

The ERP software consequently paves way for the industry to act as more organized in Industry 4.0 era. This makes them more competitive and permits them of real-time view o their production, management, and operations.

Cloud ERP is the Simplicity of Digital Business Operations:

But the question arises as to how to make plastic molds using ERP as a simple task. Usually, using and managing software in such a large industrial unit is not child’s play. It often is the case that both SMEs and large-scale industrial units work on their information system.

However, this system asks for more effort and hard work to manage the digital task. This requires a complete infrastructure, database, load of hardware units, and servers.

Nevertheless, for Injection molding, ERP cloud operation makes this process simpler. ERP easily connects its data with Microsoft Cloud Technologies. This hence saves a chunk of cash for setting a separate system as a software house.

Benefits of Using Plastic Molding for in China

There are many advantages and feasibilities of using plastic injection molding parts and products. plastic molding in China offers a variety of benefits that include:

  • State of the art Molding machinery: The injection molding in china guarantees innovation with quality products. It makes the heart of the injection molding in China. The industry uses plastic molding products, mold, and die casting which are world-class and highly competitive products. 3D tool design technology ensures efficiency and reduces mistakes.
  • Assurance of Quality Products: Plastic molding for in China offers a wide range of products with a full quality guarantee. The whole process of production is under constant monitoring to assess any possible error. The mold and molding material are checked under constant monitoring to mitigate any mistake and to ensure high-quality deliverance to customers.

4 Injection Molding Defects and Causes:

Despite the number of benefits that Plastic molding in China offers, there are several common defects. There are 4 manor defects and we discuss them from here:

Many defects are common in plastic molding in China. This happens due to many technical reasons. However, most of the defects and their causes are due to the defects in the injection mold process. Therefore, here are the 4 major defects and their causes.

Flow Marks and Flow Line

One of the most common defects in plastic molding for in China is flow marks or flow lines.  Flow marks and flow lines are the most common defects that we find in the injection molding process. Flow lines mean there are some lines or waves that are apparent on the surface. Consequently, these marks make a streak of line. Thus, this usually discolors the defected section in comparison with the rest. Therefore, the surrounding area hence becomes more distinguishable because of the color difference.

This defect is common on the gate point of the mold. These gate points or gate locations are the places where molten plastic enters the mold. However, these marks or lines do not affect the final finished product. Furthermore, the lines do not affect the functionality of the final product. The problem persists with the visual appearance of the product. It looks unpleasant and makes the product look least attractive which requires it to be aesthetically pleasing.


Plastic molding parts go through many phases and changes in the process. The last step is the cooling rate process, where the product goes through the cooling process. Hence, it passes the heated barrel and thus molds and solidifies itself in the end.

These defects usually happen when the thickness of the walls of the mold is not uniform. The variant thickness thus allows the molten material to cool at different speeds. Furthermore, another cause of the flow line is the slow injection process and low-pressure injection. This happens when the molding plastic cools down so quickly that its leaves pattern marks and lines.

Burns Marks in Plastic Molding in China:

Burn marks in plastic molding in China are the black colored marks on the edge of the final product. The marks however can also appear on the edge in the form of rust color. The marks furthermore may appear on the surface of the molded parts.

These marks are therefore not the actual part of the final product. The marks hence are harmless for the final material; However, the damage may occur if the marks burn the actual product. The burn to the final material therefore degrades the plastic.


 The most common cause of these defects is overheating. The burn marks appear when the trapped air bubbles in the molds get overheat. Furthermore, the molten risen in the molds also get overheating and thus cause burn marks. All this happens in the mold cavity during the processing time. The main cause of these issues is thus the overheating of the molded parts. It also happens when a process involves high injection speed.

Warping Defects in Plastic Molding in China:

Warping is an uneven distribution of mass or shape of the final product. In the plastic injection molding process, warping occurs when the final product cools down and solidifies unevenly. During the process of plastic production, this uneven cooling and solidification make the process defective. This makes the final product a disfigured one. The final compression product contains bends and twists.


There are many reasons for the final product to be defective in shape and form. The most common cause is the premature cooling of the raw material. Furthermore, the uneven cooling rate process causes the uneven distribution of mass and material. However, this also when there is an overheating in the process. Also, when the walls of the molds are uneven this causes the product to have warps.  

Air Pockets and Vacuum Voids:

Air Pockets in plastic molding in China are the plastic bubbles. This bubble hence usually gets trapped in the final product. The finished product thus remains unfinished. But this defect is not the major default in the final product. However, the presence of this defect in the product may cause the weakening of the final items. This happens during the product development phase.


The happens when there is a low volume production in injection molding. The vacuum voids appear in the final product when there is insufficient pressure in the mold. Low pressure happens due to low production. Therefore, in the final product, the air bubbles remain. The presence of the vacuum voids thus appears when the plastic cools down and solidifies having an air bubble in it.

Final Thoughts:

As we see there are many defects in plastic molding for in China. This happens due to the faults in the initial process of the molding machines. This also happens when the tool used is defective. Furthermore, the defects appear when the raw material used in the process is defectives. To avoid this, the design of the mold should be proper and it should properly finish the final product.
