Soft plastic lure molds

What Is A Soft Plastic Lure Mold

The soft plastic lure Mold acts as a bait to trap fishes. The main aim is to create an appeal that confuses the fish to consider the bait as its prey. The lures are often attached to reels and trap the fish once it attacks the bait.

Fishing gears have been in practice for years. Multiple innovations in the reels, rods, hooks, lures, etc., have made fishing easier, convenient, and economical. However, these advances result in cost expenditure, making it difficult for an average angler to fish while remaining within the budget.

The significant expenses include boat maintenance, fishing tackles, clothing; therefore, the overall experience might cause hundreds of dollars to the fishing community. However, with soft plastic lure molds' innovation, things have become easier for fishing enthusiasts more than ever. You may get a readymade lure Mold, but consider making one yourself if it's not within your budget. 

Soft plastic lure molds have gained massive popularity in the past few years. You cannot trick the fishes with the same old technique of using gears. Fishes have become smart, and they know the several Clichéd techniques that the fisherman has been operating for decades to trap them.

The fishing community realized that they have to keep using different methods, and therefore the use of soft plastic lure Molds became extensive. You can make a ready-to-use one or make one yourself. This molding technique allows the fabrication of thousands of different lures, thus providing umpteen ways to trap the fishes.

Types Of Soft Lure 

The soft plastic lure is an artificial bait that attracts the fish's attention and encourages the fish to attack the appeal, making it easy for anglers to trap the fish.

There are thousands of different types of lures available in the market. The distinctive kinds of Molds have unique characteristics to attack particular types of fishes. It also depends on the weather and water conditions. Here we will discuss the core types of the fishing lure.

Surface Lures

As the name indicates, this type of lure remains on the surface and can only move above the sea waters. Since the big and huge fishes swim beneath the deep bodies, the use of this type of lure is not extensive. 

Sinking Lure

The fishing community aims to target big prey and mostly resides in the deepest waters. Therefore, the sinking lure gets deeper and helps catch the targeted deepwater fishes. 

Soft Plastic Lure

Being the most prominent type of lure, it is an artificial plastic lure that resembles the natural fish and has the same movements. It is available in various materials, and thousands of different soft plastic lures are available in the market. They can be lizards, worms, squids, etc., and act as natural fish's prey. 

Floating Lures

Floating lures comprise several other attractions, and they have unique features like one can navigate them inside the deepest waters, and therefore they can even go to places where fishes hide. They can also detect the water conditions and thus act accordingly. 

Making of Soft Plastic Lure Molds 

You can make your Customized mold yourself, so you won't need to invest in readymade ones that might be of no use to you. The lures these Molds form have the same ability to swim like the natural fish's prey.

You can have a single mold as well as the multi-cavity mold of your favorite bait. Here are a few steps you can teach to fabricate your own single or multi-cavity mold. 

Plastic Resins 

First of all, you need to take a measured amount of plastic resin, depending on your mold's cavity size.

The next step is to heat the plastic mixture. The plastic contains additives that will separate, leaving air bubbles, so you need to remove the air bubbles. There are specially designed machines that will help you out in this regard. 

Heating 

Heating of the plastic resins can be crucial and requires careful consideration. The fuels that evolve out during the melting of the plastic are harmful to human health.

Therefore, put on your masks and wear gloves before you begin with the heating process. Heat the plastic resins well until they achieve the melting temperature. Make you stir in between the process to ensure equal melting and no air bubbles. 

Coloration 

Once your molten plastic achieves the required melting temperature, i.e., 325 to 350-degree Celsius, you need to have a thermometer for measurement of the weather.

The digital one will be the right choice. Once your molten mixture achieves a good agitation, you can add the specially designed colors to attract your prey's attention. You can also add glitters that will add shine to the bait, and it will become easy to capture the prey's attention. 

Reheat 

When you add the glitter, the molten mixture being lighter comes above the surface while the glitter sets down at the bottom.

This difference in viscosity can affect the agitation and pouring of the mix. Therefore, reheating the mixture for a few minutes can help achieve a well-mixed combination that will be easy to pour into the mold. 

Mold

To form a multi-cavity mold for your bait, you can use molten translucent silicone rubber and pour it on a flat square-shaped box containing tricks.

You can place as many baits depending upon the number of cavities you want your mold to have. Make sure you keep the walls of the box straight so your mold would not become round. Once it hardens, remove all the masters you place using special knives to cut silicon. The multi-cavity mold is ready to use. 

Removing The Bait

Once your plastic sets in the cavity, you can remove it using knives and cutters. It is better to use a cooling surface so that the mold would get cold quickly, and therefore you can trim the bodies which have resulted from overpouring. It is preferable to use HDPE as it can allow rapid cooling so that you can give the final shape to your bait. 

Setting Time 

Once you remove the bait from the mold cavity, give it some time to set. The preferred set time is 24 to 48 hours. After that, you can use the trick to trap your prey. This provision of set time firms the bait, making it last longer than the usual readymade ones.

Injection Molding Problems and Their Prevention

Injection plastic molding is a complex technique of creating plastic using a plastic injection molding machine.  They incorporate the technique of filling injections with molten plastic or other malleable materials and inserting them in the molds to form the desired shapes. A plastic injection molding machine needs a lot of high pressure to perform this function.

Since this is a highly complex procedure done by a plastic injection molding machine; it has a lot of room for error. The types of errors in production can vary from surface defects to safety hazards in the design of the output.

This can also cause major defects in the functionality of the product.  The occurrence of errors can be due to poor quality of raw materials, missing specifications during the procedure, and a defective design. 

Sometimes it can be a mix of all these defects too. Large amounts of defects can ruin the design as well as the reputation of the manufacturing company.

plastic injection molding machine

Molding Defects Caused by Process Problems

The cost of correcting molding errors can vary.   Very highly defective errors can be costly for the production as well as the consumer.  In order to prevent such high-end errors, it is advised to adjust molding processes, redesign the mold or replace the tools before producing the final output. 

It is better to face a loss at an initial stage rather than facing a big loss after the mass production of the plastic molds. But the best part is that it is avoidable to prevent the defects from happening altogether.  You can take easy steps of adjusting the pressure, heat-intensity, and flow rate to prevent defects from happening.

Here are some common defects that can occur during the injection molding process and some of its preventions.

Flow lines

They act as a passageway or a gate for the molten material to enter.  It is possible for a product to have these curvy designs imprinted on its own design which is not desirable by any consumer. It can be unsightly if they leave a mark on the product mold.

To prevent this from occurring, you need to make sure that the cooling speed of the molten material stays uniform.  Another remedy for this problem can be the even flow of material through the flow lines. When the speed of the molten material increases it becomes impossible for the plastic residue to stick to the pathway which is the best way to prevent clogging and unnecessary imprinting in this area. 

 

Burn Marks

This is a very common type of problem in plastic injection molding. Sometimes the product might have burn marks or discoloration on some of its surfaces.  Although they do not affect the functionality of the product itself, it can lead to some very unpleasant looking surfaces that might not be acceptable to the consumer.

Burn marks only occur when air is trapped in some parts of the machine.  Air cavities help the residue to accumulate in certain places. When the residue area heats up constantly it starts to burn and as the molten material passes by it leaves a burning imprint on the product.

To avoid this you need to lower the melting and molding temperatures in order to prevent overheating. Another remedy is to reduce the speed of injecting as well as shortening the molding time span.

Warping

Warping is an error in which the product deforms.  Some areas of the product might shrink while the others remain the normal size causing warping to occur. This can also cause due to high pressure that is uneven on different areas of the mold. One of its major causes is due to sudden cooling.  Sometimes this can also happen due to an unusual mold design. It is important to inform the design team to make a mold that can facilitate the plastic injecting in every nook and corner of the mold.

To prevent this from occurring, the manufacturers must make sure to create a cooling process that is gradual in nature. Another way to prevent this is to lower the pressures and temperature. A consistent and continuous heat and pressure flow will ensure an un-warped product.

Vacuum Voids and Air Pockets

This is the most common type of error that can be seen in injection-molded plastic.  Sometimes the design may feature air pockets in the form of air bubbles that can trap on the surface of the design.  It is a minor defect but an undesirable one.  Too many air bubbles in the design can affect the functionality of the design by weakening it. It can also cause safety hazards at the user’s end.

The major cause of the formation of air bubbles on the surface of the injection-molded plastic is uneven and insufficient pressure.  In order to prevent such occurrence, the manufacturers need to increase the injection pressure and choose a material that has a low viscosity.

Sink Marks

Sink marks feature the presence of breaks or hollows on the flat surface of a consistent design mold in the parts of the molded product where the material flow was insufficient.  Insufficient provision of material in the desired area during the process can cause depression in the design.  The reason behind the sink marks is the very slow cooling of the melted material.

In order to prevent this, the machine needs to hold the pressure for the exactly specified time and not a second less.  The cooling time must increase to prevent sink marks on the surface of the mold. What more you can do is that the design the mold with thin walls to compensate the cooling process.

 

Welding Lines

Welding lines appear when the molten material congregates after piercing in more than two directions of the mold.  Due to the weak binding of the molten material, welding lines can appear on its surface. They decrease the strength and functionality of the product significantly.

The reason may be the uneven merger of the polymers at an unspecified temperature. This can result in an even solidifying or an uneven liquefying of the polymers. 

The cooling time must increase to prevent sink marks on the surface of the mold. What more you can do is that design the mold with thin walls to compensate for the cooling process.

Jetting

Jetting is the formation of zigzag lines in the design mold. It appears as a deformation in the design surface. The occurrence of jetting takes place when the molten material enters the mold suddenly or with too much pressure.  This can weaken the design of the mold substantially.

Moreover, too much pressure while injecting the molten material can cause jetting. Usually, the injection plastic molding machines have a very small entrance. When the polymers enter the small entrance with too much pressure it can harden the material undesirably.  This can cause leave an imprint on the finished design.

To prevent jetting to happen, you need to reduce the injecting pressure. Also, increasing the material and mold temperature can prevent it from happening.  Make sure that the polymer flow is nice and easy that increases gradually.

Master molders are the ones with great knowledge and experience in dealing with products. While button-push design molded plastic molders are new I the market and don't have the skills to manage the requirements skillfully.

Design-Molded Plastics

Design-molded plastics are fabricated using molten material. To achieve the desired size and shape of the material, specially designed molds are used. The molten material solidifies into the mold cavity and attains the shape of the cavity.

plastic injection molding parts

The great thing about injection molding is accuracy and mass production. Injection molding is one of the best fabricating techniques in plastic processing.

Button-Push Design Molded Plastics Molder Vs Master Molders

There is an excess of the Button-push design molded plastic molders in the manufacturing sector. Dealing with defects and new design becomes inefficient when dealt with less knowledge and training. The operators in this sector believe in applying different techniques to deal with the defects. This can make the process costly and consume too much extra time.

Master molders have a vast knowledge of the latest techniques to provide solutions to these problems and fabricate high-quality products that result in cost-effectiveness in the long run. They know how to fabricate products according to the exact requirements of the customers and clients with their immense expertise and skills. 

The comparison mentioned below between the master molders and the Button-push design molded plastic molders elaborates why one should collaborate with the master molders. 

Polymer And Plastic Availability 

The injection molding manufacturer that you collaborate with must equip the relevant plastic resins. The master Molders being more experienced have a stronger reputation in the manufacturing sector and have contacts with plastic and polymer suppliers.

Thus, master Molders have a great variety and stock of plastics. Having hands-on experience and knowledge of a variety of plastics, they can elaborate and guide you to the correct plastic material selection.

Button-push plastic molders on other hand do not have greater experience and might not know the correct plastic materials suitable for your product. Moreover, being new in the sector, they don't have strong relations with plastic suppliers so they don't have a wide variety of plastic materials.

Educated And Trained Personnel

The master Molders having names and experience employ professional and skilled personnel to manufacture design molded plastics. The employees and workers have great experience and knowledge about plastic molding processes.

When you provide them with a design, they can understand the technicalities and help evaluate the required design. While, button-push plastic molders, being new in the sector hire engineers and trainees with less experience.

They are new in the field and don't know about evaluating the design in the required manner. It is not like they don't have skill and knowledge, but due to less experience, they might not be able to fulfill the requirements. 

Knowledge Of Material 

The manufacturer needs to have a better understanding of the materials. The production process is effective only when the raw material utilization is proper and efficient. The raw material should not go wasted as it can result in cost ineffectiveness.

The master Molders have experience and quality knowledge about the proper usage of raw materials. With their expertise and skills, they manufacture the finest quality finished product by properly utilizing the raw material and thus making the processing cost-efficient. New upcoming molders may not be as efficient as the master molders in this regard. They might not utilize raw material properly, thus making the process costly and ineffective. 

Prototyping 

A prototype is a sample of the finished and fabricated products that your company presents as a sample. Prototypes can help you give an idea about what your finished product will look like. It can also give you an idea about the service quality of the Molding manufacturer.

Master molders fabricate a large number of finished products daily. Thus you can get a hands-on idea about the service they provide. Button-push design molded plastic molders are new in the field and don't have many finished and fabricated products. So, it will become more difficult for you to trust their service. Hence, while investing in something, you must learn about the quality of the finished product that is in this regard is possible with master Molders. 

Efficiency And Quality 

While considering your Molding manufacturer you look for their relation and repute in the sector. Being experienced, master Molders are more aware of the latest Molding techniques and modern equipment and machinery to fabricate finished products.

ISO certification is also important while considering the manufacturer. Most Master molders with their expertise and experience, are ISO certified. Having more experience, you can get every possible information about their services from their suppliers.

This is not possible with the Button-push design molded plastic molders as there is no background knowledge available about them. They are new in the sector and are on their way to build their reputation in the sector.

You need to trust them as they can't get information about their previous work and services. Thus, there is a risk factor you need to deal with while collaborating with Button-push plastic molders.

 Cost Factor 

Coming to the last and very important point is the cost. Master Molders with great expertise, skills, and experience fabricate products with high-quality and required details and design. But due to their quality provision of finished products they charge much more than what a new molder will charge for the same service.

Button-push design molded plastic molders being inexperienced charge the amount within the reach of any client. Their main aim is to gain clients, and for that purpose, they keep their rates quite lower than the master molders. But as we have already studied the comparison between the two sectors, master Molders take the lead.

You can get your required product at much higher rates from master Molders, but the hassle and worry about the results and services is what makes them superior to the Button-push design molded plastic molders.

Conclusion

To sum up, master molders having great expertise and skills in plastic processing can deal with a wide variety and defects and plastic processing. They have more experienced employees and trained personnel, and the latest equipment and machinery to fabricate a wide range of products.

Button-push molders don’t have enough experience and knowledge about the different and unique fabrication techniques and thus one cannot rely on collaborating with them.

China Plastic Injection Molding: What the Molders Think

Every single material is made up of various physical attributes. You must use appropriate procedures and information to make sure that the processes are right and repeatable. Read this article to know a molder’s perspective about china plastic injection molding.

You May Also Read: Common Overmolding Materials Used by Plastic Molding For China Man..

This article will cover different material properties in a way that even an average person can understand easily. But first, let’s see how a molder thinks about it.

A Molder’s Prospective about China Plastic Injection Molding

All processors use different sorts of engineered resins for molding parts. Every single resin has unique characteristics. The performance of polypropylene is different than nylon; the processing characteristics of amorphous materials and crystalline resins are different.

china plastic injection molding

The material subject is diverse and many experts have made their careers because of their vast knowledge about this complex subject.

The job of a molder can become easier by recognizing and practicing various common factors. However, density and tensile strength are two important elements of the SDS (Safety Data Sheet) data to an engineer who has to pick a material for a specific application.

A process engineer does not require this information for developing the process. It is extremely important to know the compulsory information required for process development.

What is Plastic Injection Molding Used For?

Plastic injection molding is a process to manufacture molded products through plastic materials injection liquefied by the heat into the mold. Manufacturers use it for creating several things, like wire spools, automotive components and parts, small tables and chairs, packaging, musical instruments, mechanical parts, bottle caps, and storage containers, etc.

There is a wide range of plastic products that manufacturers create by china plastic injection molding technology.

Here are a few commonly used materials for plastic injection molding:

  • Nylon (Polyamide)
  • Polycarbonate
  • Acrylic
  • Polyoxymethylene
  • Polystyrene
  • Acrylonitrile Butadiene Styrene
  • Polypropylene
  • Polyethylene

There is an extensive list of other plastic materials that are also used for injection molding.

Basic Material Properties

Let’s discuss some fundamental material properties from the perspective of a molder. This will help you understand the complex terminologies even if you are a lame man.

  1. Viscosity

In simple words, viscosity is the material thickness in its liquefied flowing form. Just hold a board at an angle and pour down corn syrup and water on it. The water will flow easily as it is quite thin with low viscosity. On the other hand, corn syrup will flow slower because it is thicker and has a higher viscosity.

When we talk about the engineered resins, there is an uninterrupted relationship between specific gravity numbers and styrene viscosity. Styrene is known as the mean (middle point) of the material viscosity scale.

The material will have higher viscosity if it has a positive gravity number. On contrary, the materials with negative gravity numbers will have lower viscosity. Therefore, the viscosity of styrene depends on how low or high the SG numbers are.

  1. Melt Temperature

Melt temperature (MT) is often one of the most overlooked SDS variables. The melt’s temperature that is coming out from a barrel is very important in establishing primary set-points for the process. Melt temperature needs to be set at low in the initial process development stage. This will make sure that the barrel temperature is not a huge factor while establishing the cycle time.

  1. Barrel Temperature

Safety Data Sheet (SDS) usually provides the set-points of barrel temperature that serve well as the starting point temperature. Here, you must understand that adjustments might be required to the set-points to ensure desired melt temperatures.

It is imperative to confirm that the actual temperatures of the transition zone don’t supersede the set-points. If it is superseding the set-points, then it’s a sign that the barrel shear is unnecessarily greater than the set-points. You also need to confirm that the timing of screw rotation is consistent. A lower temperature in the feed zone can produce poor feeding in the feed throat.

  1. Drying

China plastic injection molding material companies also provide drying information of their material which is important to the processing requirements. You must explicitly follow the information that comes with the material. It is imperative to evaluate dryers to make sure their size is appropriate and meets the desired drying time.

Here, you should know that the material in the middle of the dryer flows faster than the material against dryer walls. If you choose a dryer that has a throughput very near to the desired drying time, then it may cause processing errors.

Moreover, there are always chances that the materials may also over-dry. In a dryer, some materials may stand long events, but keep in mind that the material blends comprise of various diverse basis, pigments, and additives, etc. As a best practice, you should set dryer temperatures periodically that the material sits idle for 8 or more hours in the dryer.

  1. Back Pressure

This is something that is not always incorporated on the Safety Data Sheet. However, this parameter still has critical importance in the processing scope. The best solution is that you use slight back pressure to minimize the breakdown of the molecular chains.

If backpressure is overlooked, then it can cause processing inefficiencies. And in case of the reinforced plastics, such as metal strands and glass, it can also result in poor structural/physical qualities.

  1. Injection Speed

Injection speed is always a top consideration during the process development. A few materials may work better at the faster speeds while some work best at the slower speeds. We advise you to start the injection speed in processing the widow’s middle. After that, adjust speeds according to the molding variables when they show themselves.

It is extremely important to understand that temperature, viscosity, and speeds are directly proportional to each other. 

High Temperature = Low Viscosity = Fast Fill Speeds = Low Fill Time

Low Temperature = High Viscosity = Slow Fill Speeds = High Fill Time

For flawless process development, understanding material properties, and information that the manufacturers provide is essential. Different materials come with different arrays of attributes.

So, you must use appropriate procedures and information to ensure that the process completes flawlessly. Process development holds significant importance in the failure or success of every china plastic injection molding company.

Plastic molding is a very common practice in many commercial and domestic applications. There are many china plastic injection molding companies that you can choose from for your plastic molding needs.

But, you need to hire the best company that offers unparalleled, specialized services by meeting the desired service standards. While hiring a company, you must ask them for their certifications and previous work history. You should also make sure that the company you choose offers round-the-clock customer support.

Plastic Molding For China Manufacturers: Common Overmolding Materials 

Plastic Overmolding is an injection molding method in which one material (typically TPE) manufacturers mold one material onto another material (usually a stiff plastic). They do this molding process through pressure and heat alongside liquid silicon. The TPE over-molding design establishes a solid bond with plastic maintained in an end-user environment. There is no need for adhesives or primers for achieving a solid bond between both materials. Plastic molding for china is known as a highly reliable method of molding plastic for various applications.

Common Overmolding Materials for Plastic Molding for China

When choosing Overmolding materials you must make sure that the selected materials are fully compatible. There must be a solid bond between the two materials both physically and chemically. Otherwise, the finishing and life of the component will never be as you desire. If there is a compatibility issue, then you will experience issues, such as Overmolding failures and component deformation.

plastic molding for china

There are literally thousands of materials available that you can use for Overmolding, but you really need to choose the best one. This selection process normally involves an engineered resin specialist. Specialists can help you on bonding compatibilities, innate properties, appearance, cost, regulatory compliance and other major aspects.

Here are a few common over-molding materials that you may choose to make the best combination:

  • ABS
  • HDPE
  • POM (Acetal Copolymer)
  • Acrylic (PMMA)
  • PBTR
  • PEI
  • PEEK

Selection of the appropriate material is not only critical in the success of your component in the application, but it is also equally important in marketplace.

Why Plastic Overmolding?

One major reason why Overmolding designs are selected for plastic molding for china is that they actually improve the functionality and aesthetic design of the product. With the help of plastic Overmolding, you can practically create several color options. Critical details can also be added easily to the products keeping in mind the specific use of the consumer. For instance, you can fit a screwdriver with a comfortable and colorful handle with the help of Overmolding method.

Here are more reasons why plastic Overmolding is a popular choice:

  • Plastic Overmolding ensures a soft surface grip around the parts of a separate material.
  • Breakup color (aesthetically important).
  • Adds Flexibility to the rigid parts.
  • Removes the assembly line time. Rather than manufacturing plastic grip and metal tool separately and joining them together afterwards with automation or manually, you can simply over-mold both together at the same time. This makes the process really fast.
  • With plastic Overmolding, one part can be captured inside another without even using adhesives or fasteners.

So, now you can understand that why Overmolding is a preferred option for plastic molding for china over may other methods.

Different Types of Plastic Injection Overmolding Process

There are basically two types of plastic molding processes available that govern the manufacturing of a substrate molded part. Here are those two types:

  1. Insert Molding

Insert molding is currently recognized as the most widely used and common molding process used for plastic molding in china. The process happens when you place a e-molded insert into the mold and TPE is directly shot over it. One major benefit of using this molding design type is that you can simply use the traditional single shot machines (IM) and the cost of tooling linked with the insert plastic molding are also very low in comparison to multi-shot processing.

  1. Multi-Material Plastic Overmolding

This is a pressure and heat substrate molding that needs a unique plastic injection molding mechanism. You need to fit the mechanism or machine with at least two barrels that ensure that a minimum of two materials can be shot easily into the mold during the molding cycle. This plastic Overmolding type is ideal when reducing cycle times is important and you also want to achieve enhanced part quality. Another advantage is that it also reduces the labor costs.

Benefits of Plastic Overmolding

Plastic Overmolding is popular because it helps create high quality, durable end products at low labor costs. Some other benefits include, but not limited to:

  • The overmolded parts ensure appropriate alignment and prevent loosening.
  • The plastic resin ensures enhanced resistance to shock and vibration.
  • Enhanced part structure and strength.
  • Improved multi-material components and design flexibility.
  • Less secondary operations, labor and assembly costs.
  • The bonding process in manufacturing is eliminated that results in enhanced component reliability.

Above were just a few advantages that come with Overmolding process. There are many other factors for which a molder chooses this method.

Application Areas

Manufacturers use Overmolding for a number of purposes in different application areas including electronic devices, controls, automotive, medical devices, appliances, and more. Many products that you see around are made using this technology.

Overmolding Material Selection

There are various types of Overmolding design materials available. Those materials can be softer, harder, or a blend of both. Such designs need a “squishy” or “grippy” quality about the handle. So, what are the factors that determine which materials manufacturers need to use in order to ensure the quality requirements? Here is what you need to know to determine what materials you need for the required effect.

  1. Thickness Effects

A designer may opt for the softest available material for the soft touch TPE. What he might be missing is the fact that the TPE’s soft durometer offers a little value to “cushion” concept when the TPE thickness is under a specific point (usually > 0.040). Keeping this in mind, the TPE overmold will get harder as it gets thinner. One solution to this problem is that you should incorporate various ribs and place them together closely to create thickness perception without the use of large material amount.

  1. Modulus vs. Hardness

The hardness (or durmeter) of the material is directly linked with its flexibility, which is a common myth in TPE industry. However, this thing isn’t always true. For instance, the material 65 Shore A SEBS has greater flexibility than the material 65 Shore A TPU. Rather than using the Shore Hardness, flexural modulus is a more appropriate flexibility measure that measures the bending resistance of the material. If the flexural modulus is high, then it means that the material will be more unyielding and stiff.

  1. Coefficient of Friction

A force creates between two surfaces that slide or try to slide across each other. We call this force friction. The COF (coefficient of friction) describes the amount of force you need to move a surface across the other surface - either from the static friction or kinetic friction.

Normally, we describe TPE as “grippy” or rubbery. The relationship between COF ad durometer is an important area that designers misunderstand quite often. Most designers think that the softer TPE means greater COF which is not a true statement in all cases.

Plastic Mold Maker: Determining the Cost of Mold

Molding (or Moulding) is a manufacturing process of shaping a pliable or liquid material using a matrix or mold. The material is shaped with the help of a stiff frame. Plastic is molded by placing liquid or powder-like polypropylene or polyethylene into the hollow mold. After that, the polymer gets the shape of a hollow mold. Different arrays of pressure and heat are used to manufacture the end products. Plastic molding is required for various domestic ad commercial purposes. When you hire a plastic mold maker for your project, the cost of the mold will depend on several different factors.

Consider Different Factors to Decide the Molding Cost

A plastic mold company or maker considers different important factors to offer price quotes to its customers. If you want to hire a mold maker for your plastic injection molding project, keep in mind the following pricing factors.

Dongguan plastic molding company

  1. Design of Part

The pricing of plastic molding depends on the design of the part. The intricate parts require intricate mold that means the tool costs will be higher. If you want to reduce the costs, then you should keep your design simple. Sometimes, a small but complex mold proves more expensive than a simple design large mold.

  1. Size of Part

Apart from the design, the part’s size also influences the molding cost. If the part is larger, then the molds will also be larger. In that case, more material will be used. The machining time also goes up to mold larger parts. A thin, small part molding process will be completed faster than the molding of large parts. Therefore, molding large size parts results in higher costs.

  1. Resin Selection

The resin that you choose also affects the plastic molding cost that the plastic mold maker is going to charge. There are various factors behind it, such as availability, quantity, the value of the resin, color, additives, compounding, and grade. The mold temperature requirement is another important factor in pricing molding. If the selected resin contains abrasive materials, like mineral, carbon fiber, or glass, then it may also affect the mold’s maintenance cost.

  1. Cavities ad Volume

For volumes, hours are required to be spent in the production process. The projects with higher volumes require high-quality tools to ensure reliable service. Therefore, higher production time and the requirement of high-quality tools result in a higher cost. The manufacturing cost also depends on the cavities number. Higher cavities result in long ‘press time’, resulting in more project cost.

  1. Cycle Time

Another influencing factor in setting up the molding cost by a plastic mold maker is the ‘Cycle Time’. To ensure a rapid machine cycle, uniform cooling is required by the tool through cavity impressions. This means that the tool will need greater precision build and it will increase both tool maintenance and construction costs.

  1. Part Tolerance

If a part has tight tolerance, then it will require extra steps during the mold manufacturing. This will increase the tool cost. However, the value that you gain with tight tolerance will always pay off in the log run. This is why you should always look for a plastic mold maker that specializes in tight tolerance.

  1. Onshore or Offshore Manufacturing

The upfront plastic molding costs from an overseas company may be lower, but they often end up being more expensive in the long run. Therefore, you should look for a local company, but make sure the company is reliable.

  1. Tool Material

The biggest upfront cost of plastic molding is normally the mold itself. While molds come in several variables (including complexity ad size), the selected material also impacts that cost.

The standard mold materials are aluminum and steel and both have certain qualities that offer different benefits over others. However, aluminum material is easily available and it has greater thermal heat transfer. You should share your expectations with the manufacturer so that they can help you select the best possible material.

If you have got the required information, then having the right tools and hiring the best plastic mold maker will become a straightforward job. And if you don’t have the right information, then it may become a scary process.

Things to Know Before Hiring a Plastic Mold Maker

Before you hire a molding company, here are the most important things that you must ask them first:

  1. Know Specifications of your Material

Your DFM engineers need to specify the exact plastic-type that you plan to use for your parts. There are different types of plastics available and many of them require specific tools for molding. All materials don’t heat, cool, or shrink at the same rates.

For an efficient and quick running of tools, the designer needs to take this factor into consideration, while designing the molds. Keep in mind that only a few seconds delay in manufacturing your parts can result in hundreds of dollars’ value of additional costs for producing the product.

  1. Get Accurate Production Estimates

You must determine the number of cavities the mold might have. For this, you need to have a very precise estimate of how many parts you need to run at the beginning of the production. You should also be very clear about your long-term production objectives.

  1. Prototype and Full Production Mold

When a product is in its prototype stage, the prototype mold might be a necessity. But, it requires parts of production-quality in large quantities for justifying the investment. Therefore, you must discuss this thing with the company.

  1. It Is Not Quick or Easy To Quote Tooling

This is one reason why you are supposed to invest in the DFM. A DFM manager can easily determine the mold complexity and sizes of tools required. He will also be communicating with the plastic mold maker and the molder all the way through the process.

When mold is quoted, there is much to consider, so you must make sure what the parts will be doing and what they will need. This will save a bulk of unnecessary work.

The production of tooling is also not very quick or easy. You also need to ask mold makers for their recommendations about cold-runner or hot-runner systems. Another important thing is to know whether or not the tool design will need a secondary process. If yes, then will it really add additional cost to your goods sold?
