Plastic injection mold design is an extremely important step in the entire mold manufacturing process. More importantly, in this article, we will learn about the design and manufacture of high-quality plastic injection molds in China.
Stages of plastic molding kit
Plastic molding kit design stages include:
1. Evaluation of manufacturability and feasibility
In the early stages of a plastic injection mold design project, a team of design, production, and assembly engineers will work together to define product specifications, components, materials, mold functions, methods to limit errors. Furthermore, these may arise and make necessary improvements on the product.
During this stage, we should give special attention to analyzing potential problems in the shape and tolerances of plastic injection molds to minimize the occurrence of undesirable conditions. Lastly, it is necessary to select mold materials and calculate cooling parameters
Requirements for plastic injection molding
In addition, the research team for plastic molding kit will evaluate the mold flow to select the most suitable injection port type and port location, as well as determine the appropriate exhaust location. Apart from this, plastic injection mold manufacturers also need to develop a process of analyzing and assessing possible risks in production.
2. Design on software for plastic molding kit

3. Pin final design specifications
The design specifications of the molded parts are the key to building the finished product on the design software. In addition, strict final adjustments and revisions require prior to implementation to meet manufacturability and critical requirements.
Three factors influencing molding plastic at home
We can say that three main factors directly influence the quality of the molding plastic at home: the mold, the material (raw material), and the process. We'll talk about them in this article. Also, get to know some points of attention that are needed during the injection process
1-Molding plastic at home
The plastic injection molding machine is easy to influence by items such as distribution channels, cold wells, and temperature uniformity. Composed of steel, the mold tool can contain mobile or stationary plates, which define the shape of the produced part.
The final material is then pushed out of the mold via ejector pins. A coolant (usually water) passes through the material to remove some of the heat and prevent overheating. For molding plastic at home not to impair the proper functioning of the mold, it is important to consider the following items:
Distribution channels of molding plastic at home:
These are responsible for transferring the molten material from the nozzle to the cavity inlets.
Cold well in molding plastic at home:
It serves to absorb the colder flow in front of the material. The machinery is usually composed of a primary cold well and a secondary one. See below for an example of a cold well distribution channel. This links to molding plastic at home
- it is also necessary to be aware and check for stains on the piece.
- Second, when it happens, part of the cold material goes towards it.
- Above all, if there are no stains, this content will go directly to the cold well.
Temperature uniformity in molding plastic at home:
It is in the mold that the final part is created; that is, it is necessary to pay attention to quality throughout the injection process. The temperature has a great influence in this sense, as it can interfere with the part's finishing, internal tensions, dimensional stability.
Other items of attention regarding the mold common in the injection:
- Internal pressure sensors: can be common in the mold to control the variables of the plastic injection process.
- Design review: it is important that it is validated with the departments involved before releasing the mold for construction. It should be considered:
- First, product geometry and exit angles
- Second, distribution channels / hot runner
- Third, the temperature control system of molding plastic at home
- Moreover, the mechanical reliability of moving parts
- Above all, define the preventive maintenance plan.
How can you ensure molding plastic at home protection?
Mold protection is worth mentioning that all injection molding machines include mold protection from the oldest to the newest. When done properly, it helps to ensure efficient injection of thermoplastics.
It basically requires the operator to check the position of the mold and adjust its pressure and speed. reduced.
2. Raw material common in plastic injection
Initially, it is necessary to carry out a previous and detailed study of the thermoplastic resin to be common, according to what you want to obtain as a final product. In molding plastic at home remember that each resin belongs to a family, which in turn counts certain amounts of grades.
3. Process of molding plastic at home
First, it is important to know that the drying time of the molded material directly affects its final strength. Thus, once the ideal drying time is respected, the greater the resistance of the piece. Another highlight of molding plastic at home is the temperature and pressure common in the injection process.
Each step requires a certain temperature to work well. As we can see, the higher the temperature, the more there is contraction and degradation of the material. Likewise, the holding pressure influences the filling and burr creation of the parts. Pay attention to the ideal balance for safe, quality plastic injection.
Variables in molding plastic at home
As you can see, there are many more variables involved in the injection process than mold and raw material/material variables. Therefore, it is necessary to be extra careful with the process to guarantee the quality and performance of the final product.
In addition to drying time and material temperature, pay attention to mold temperature control, rework after injection. Apart from these in molding plastic, temperature control and cavity filling, in the case of molds with hot runners, also link.
What are the characteristics of the best molding plastic at home
A good, molded part requires basic principles such as knowledge of the physical properties and processing characteristics of the material, in addition to adjusting the equipment at the appropriate temperatures for the cylinder and mold.
A fast-cycle part calls for lower temperatures, especially in the mold.
Considerations for molding plastic
Listed ahead are 4 considerations for molding plastic at home
To achieve greater precision in the positioning of the spindle and repeatability in the metering volume, it is generally advisable to adjust the metering profile with higher initial speeds. This number decreases as the cylinder is loaded and during cooling to increase cylinder life and prevent raw material degradation.
It is also necessary to control the backpressure, which allows for greater homogenization and gas elimination. Its poor management can lead to degradation, breakage of the molecular chain, detachment of fibers, or even a reduction in the useful life of the cylinders.
Generally, molding plastic at home's pressure must be scaled down. In this way, when the injected solidifies, internal tensions avoid. However, this must come with caution because sudden drops before the gate freezes can cause the material to return to the cylinder, which causes material reorientation.
4-Plastic injection safety
Good results also involve the safety of plastic injection molding operators. Therefore, it is important that your company is aware of and adequate to the security requirements.
Final considerations on molding plastic at home
By being careful with all these variables of molding plastic at home (involving a plastic injection process), it is possible to achieve excellent results in the parts produced. In this sense, the search for knowledge, constant updating, and security are essential points that make the difference in positioning your company in the market.
Also called "plastic injection", injection vacuum molding plastic is a process for using thermoplastic materials to create different types of parts. This is a manufacturing technique increasingly common in industrial firms. It will therefore be useful if you want to launch your industrial project. Here are a few advantages.
Mass production of complex vacuum molding plastic parts
The first advantage of injection molding is to promote the large-scale production of difficult-to-design parts. In fact, plastic injection is a high-precision process which makes it possible to reproduce very complex parts by pressing the plastic into the mold. This process makes it possible to generate any type of shape.
The technique of plastic injection molding is also suitable for vacuum molding plastic. In fact, it is a rapid production technique that allows a high completion rate to be achieved in record time. However, note that the production speed depends on the complexity and size of the part to be reproduced.
The manufacture of resistant, qualitative and ecological parts
Injection molding meets the need for product longevity which increasingly characterizes the industrial sector. Indeed, in order to manufacture more durable parts, metals are increasingly replaced by thermoplastic materials, common in plastic injection method. This makes it possible to create pieces that are both light and resistant.
Also, note that injection molding can produce parts with dimensional accuracy that no other process can achieve. The use of vacuum molding plastic makes it possible to obtain this accuracy of measurements which is essential in the final assembly of the parts. The surface of the parts also benefits from this high dimensional precision to give the desired look and feel.
Use of injection molding
Besides, the use of injection molding as a production technique has an ecological advantage. Indeed, this technique helps to limit the production of plastic waste, given the small amount of material common. Finally, with plastic injection, waste is easy to recycle, which considerably reduces environmental pollution, a problem that is still worrying in the industrial sector.
Great freedom of design and the best economical choice
By promoting the use of various types of plastics, the vacuum molding plastic technique has a great advantage of flexibility and therefore freedom in the design of parts. Thus, the choice and the adjustment of the appropriate materials favor the production of perfect parts.
Also, be aware that the injection molding method has several economic advantages. First, this technique allows companies to save both manufacturing costs and labor costs. We explain this by the fact that the same materials are easy to recycle and common several times and also by the use of robotization of production.
Vacuum molding plastic Trends
1 – Sustainability
Currently, sustainability and conscientious actions that aim to preserve the environment are being inserted in different segments, since the future of the planet depends on responsible actions taken today. The vacuum molding plastic market is no different: the main objective is to reduce the emission of polluting gases into the atmosphere and reduce waste and debris that go to landfills.
Sustainable actions go beyond just a good logistical speech, but directly affect, in a positive way, the environment and the health of living beings. There are even specialists who offer sustainable solutions efficiently, such as: the replacement of non-recyclable materials with recyclable options.
This innovation will have as its main focus:
Improper disposal of plastics considerably harms the environment. This proposal allows the production of all materials through the injection of plastic, allowing it to be 100% recyclable.
The inclusion of biodegradable materials, such as bioplastics, is already a reality; the trend is that in the year 2021 this alternative will increase.
The bio plastics use renewable biomass in its composition products, enabling its decomposition does not harm the environment. We estimate that vacuum molding plastic will grow on average 20% next year. Packaging develops with raw materials such as sugar cane and cassava.
2 – Technology
Plastic injection molding is not something new in this market, but the increase in production still brings great benefits to this segment. Through it, it is possible for the pieces to gain more value and become more accessible. Currently, technological trends have offered significant changes in this sector; the insertion of automation software allows for a safe analysis of the plastic flow.
The year 2020 comes by changes in the way of buying, selling and producing. With social isolation, companies and consumers discovered that it was possible to continue producing and buying. Technologies were great allies in this period, and the trend is for them to remain in the year 2021. It is noteworthy that the focus on sustainable vacuum molding plastic will still be a priority.
3 – Projections for the future
If you've come this far, you could understand that the projections point to significant changes in different sectors. The plastic molding market is no different. Conscious actions aimed at developing green technologies are already a reality.
Studies and research claim that these actions will increase. On the other hand, the use of disposable plastics that harm the environment will be reduced.
How to control the pressure in vacuum molding plastic?
The shrinkage of the Vacuum molding plastic is related to the specific volume. As the pressure in the cavity increases, the specific volume decreases. As the pressure of the plastic in the cavity increases, the effects of contraction of the part reduce.
An unbalanced mold is reflected in:
- Quality of the pieces
- variations -Appearance and weight; between cavity and cavity
The cavity that you fill first may end with burrs and the rest of the cavities remain less.
In summary, as a good process technician you must make sure that the mold you are injecting meets a good balance. This is easy to do through fill studies and verify the variation or standard deviation does not exceed the limits allowed in injection molding.
Conclusion Vacuum Molding Plastic
Vacuum molding plastic applications that are reusable and recyclable are environmentally friendly alternatives that bring benefits to this industry.
If you believe in this change, insert these innovations into your company and look for new alternatives. A look to the future implies conscious attitudes today. Through this article, you could see how much actions like this are necessary and important for everyone.
Each plastic product has a plastic t molding, the size and texture of the mold depends on the size and shape of the product. In this article, we take a closer look at manufacturing plastic injection molds.
What is plastic t molding?
Nowadays, the concept of plastic t molding has become quite familiar to people in the mold industry, or even to those who use the product, they understand that all plastic products are molded and pressed from plastic molds.
A plastic injection mold is a component assembly consisting of many parts assembled together, where liquid plastic is injected into it and then cooled, forming the shape of the product and being pushed out of the mold.
Uses of plastic molding.
In the structure of a machine system to produce plastic products, the plastic injection mold is an extremely important device. For the plastic t molding to work effectively; create a plastic product of good quality. It must meet the standards for a standard technical structure.
Plastic t molding design
The plastic injection mold design must be up to the details of the mold including the design of the mold shell, the mold core, the mold core details, the mold components. From these detailed designs, a complete design of the mold will be formed.
The requirements of the design must provide the viewer with full details of the projection angles, sections, dimensions, tolerances, and technical requirements of each item to be manufactured. Moreover, the product (plastic t molding) design must be very beautiful
Details on t molding
The mold details include mold shell plates, mold cores, mold core details, mold components to form a set of molds. Therefore, the fabrication drawing must provide the viewer with full details of the projection angles, sections, dimensions, tolerances, and technical requirements of each item to be processed.
How to make and produce plastic molds?
To manufacture and produce a precise plastic mold according to technical standards with an accuracy of 1/100 mm, the mold must be manufactured according to the required standards. First, it is necessary to pay attention to the material that makes up the mold.
The main material common to make the plastic t molding is different types of steel with high strength. Also has good bearing capacity when put into continuous pressing to mold plastic products. Technical experts will put steel blocks into milling, cutting into standard sized metal parts.
Milling and trimming stage in plastic t molding
This milling and trimming stage is very important because it will process standard mold parts with high precision. Mold manufacturing always consists of 2 halves, one half has many parts and components, people punch holes at precise points on half of the steel mold.
So that, the upper bar fits exactly into the hole, keeping the 2 halves matched. together when pouring plastic. After the steel block is forming the mold, it will be put into roughening surface roughening to perform the processing step to turn the steel block into a plastic t molding.
An insight on CNC; computer-controlled machine
Another type of machine controlled from a computer called CNC will slowly grind the steel block to shape each part. This CNC machine is also responsible for making copper electrodes shaped like the plastic part that we want to produce to make micro-parts with a slide tool.
After the copper electrode has been smoothed, the electrode will be brought down to contact the machine below for electrolysis. The bottom half is the other half of the mold that is shaped and punched as described in the first step. Electric current is passed in electrode and imprinted on the die
Engraving letter on surface of plastic t molding
After the plastic t molding is finished processing, the surface of the print is still rough, it will have to do another step to polish the mold. The gloss of the mold will help to produce smooth plastic products. Currently, plastic products are often printed with labels right on the surface of the product,
So, the mold making process will take one more step, it is necessary to engrave inverted letters in the mold cavity. After the plastic product is molded, the inverted words in the mold will become real words and float on the surface of the product.
Steel type with quality affects plastic injection mold performance
The process of creating a set of plastic t molding from design, assembly, inspection, and repair to entering the plastic injection cycle has many details. That are worked together. Attention should be paid to the selection of steel with appropriate quality.
So as not to adversely affect the performance of the plastic injection mold. Steel type and quality determine the degree of rust and wear during use and storage. Various steels can be common to make individual parts on one die such as SKD11 steel, SKD61 steel.
Considerations for plastic t molding
When choosing tool steel, it is necessary to base on the following points:
- First, choose a steel that is resistant to corrosion and good polishing
- Second, select the most optimal steel based on the price and quality of steel
- Also, nitrogen treatment on steel surfaces contributes to increased hardness and surface life
- Moreover, use electroplating to change the performance of plastic t molding (steel)
- Above all, choose a steel type and a reputable and quality steel material supplier

Scope of Pigments of aluminum soft plastic application
Engineers of our company use technology to manufacture sheets, films, pipes.
Also, the technique allows the production of other consumer goods with a minimum investment of resources. There is a scope for aluminum soft plastic molds.
Quality and Polymers.
Products meet high-quality standards; do not require final revision and adjustments after solidification. Furthermore, they come on flexible and rigid PVC, nylon, elastomers.
Pigments of aluminum soft plastic
To give the details a particular shade, coloring pigments are common. It covers stabilizers and modifiers and stabilizers. The pigment common in aluminum soft plastic molds minimizes the risk of product degradation in direct sunlight and increases shock resistance.
Modifiers. For the melt to have the required viscosity and fluidity, modifiers are added in specific proportions.
- Necessary equipment to start up the extrusion line
Choice of the method depends on the thermoplastic or thermosetting type of material, its fluidity. Moreover, in aluminum soft plastic molds, viscosity is also involved. Furthermore, this needs to maintain the configuration and dimensions of the finished products.
The most common equipment for this type of molding is hydraulic presses. The shape that follows the contours of the future product comes with a thermosetting melt under pressure; mold is removed.
The method also uses specially made closed molds, which make it possible to obtain hollow objects weighing up to several kilograms, with walls 1-20 mm thick.
The polymers melted to a state of fluidity fill the molding cavities, and solidify in the same place. Injection molding is common in aluminum soft plastic molds.
The advantage of the method is the possibility of obtaining semi-finished products of unlimited length. It is based on the extrusion of a polymer melt through a forming head with the desired profile.
The second advantage is that virtually all types of modern polymers is easy to process using this method.
- Industrial extruders
Industrial extruders are available in single, twin, multi-screw, disc, and blow molding. The latter plays a major role in extrusion blow molding methods.
But for the production of plastic products, one extruder is not enough. So, under aluminum soft plastic molds, several more pieces of equipment are common, combined into an extrusion line.
- Products obtained by extrusion are very diverse:
Polymer films and sheets, pipes, and profiles are produced using single-screw equipment. Degassing twin-screw extruders have PVC construction products.
The well-known our company in extrusion production of molded products of decent quality and those obtained by casting. Plastic products are manufactured in a factory using modern high-tech equipment.
- Die forming
The required configuration comes with a stamp and cooled to fix it. This is how aluminum, soft plastic molds, glass cabins, fairings, visors, and other products of an open circuit we get.
- Pneumatic molding
Pneumatic molding and vacuum versions produce complex parts of optics, lighting technology from thermoplastics.
They are based on the same principles of heating-shaping-cooling.
Only atmospheric pressure and vacuum act as a stamp. The possibilities of these methods have been expanded to obtain large-sized goods and plastics with fillers - fiberglass and fiberglass.
- 3D printing
3D printing can be called a mass phenomenon, as its applications are constantly expanding. Three-dimensional technologies never cease to improve, thanks to which they have taken a strong position in the market.
Aluminum soft plastic molds use a 3D printer, and you can print a three-dimensional model of a product and obtain a physical object corresponding to the specified parameters.
In what areas is Aluminum soft plastic molds 3D printing common?
3D printing is a layer-by-layer build-up of an object according to a pre-built three-dimensional model from various materials: metal, plastic, paper, plaster, photopolymer, and others.

Hydraulic plastic injection machine
Hydraulic mold clamping machine
The hydraulic mold clamping machine is a plastic injection machine that uses a hydraulic system to open and close the mold and maintain that clamping force.
The hydraulic system also makes the screw rotate, move back and forth and give force to the pushpin. This system includes a pump, valve, motor, pipeline, and oil tank. Etc.
Electric plastic injection machine
It is a plastic injection-based machine that uses a servo motor to adjust the mold opening, closing, and mold pliers, pushing the backing pin.
Some of these machines also come with a servo motor to control the back and forth movement of the screw. This machine does plastic injection molding. As far as I know, the electric plastic injection machine appeared on the market around 2005 in Japan.
The electric injection molding machine
A popular electric plastic injection machine on the market
Should you choose an electric plastic injection machine or a hydraulic plastic injection machine?
To give sincere and accurate advice in choosing an electric plastic injection machine or a hydraulic plastic injection machine is not easy. Each type of machine has its advantages and disadvantages.
Therefore, depending on the specific job, you can buy the appropriate plastic injection machine to bring the highest economic efficiency. Below I will compare these two lines of plastic injection molding machines according to the essential criteria so that readers can make the best decision.
About power consumption:
Electric plastic injection machines save you 20-40% of electricity consumption compared to hydraulic plastic injection machines. This is understandable because the hydraulic plastic injection machine uses a hydraulic system.
Construction of plastic injection molding
It includes pumps and motors to recycle hydraulic oil to supply the whole system even when there is no requirement. As for the plastic injection machine controlled by Servo motor, plastic injection molding only works and generates power loss when it is necessary to close, open the mold, and move the screw.
The hydraulic plastic injection molding machine has a faster opening and closing speed than the electric plastic injection machine because the efficiency of this type of motor at present has a lower rate.
How does plastic injection molding increase productivity?
Depending on the specific jobs is a disadvantage of the electric motor because if the opening and closing take too long, it will affect the injection molding cycle. However, if the products need a lot of time to cool, using an electric plastic injection machine is not a disadvantage. On the contrary, plastic injection molding will increase your productivity.
Electric plastic injection machines are not suitable for products that need considerable injection pressure and large mold clamping force. It is effortless to get bogged down with the parting surface.
A considerable advantage of the electric plastic injection machine is that there are no hydraulic pumps, pump motors, valves, pipes. Hence, it is much lighter and neater than the hydraulic plastic injection machine.
A typical plastic injection molding machine needs about 300 liters of hydraulic oil to operate, also a small cost. In addition, during operation, I found that the electric plastic injection machine operates more quietly than the hydraulic plastic injection machine.
About the price.
Electric plastic injection molding machine is a relatively new technology. Therefore, the cost for you to own this type of machine is also much higher than that of a hydraulic plastic injection machine.
Besides, if you need to buy an old machine, it is not easy to find a cheap electric plastic injection machine because the life of this machine is very high.
Injection molding machines China
In the market of plastic injection machines in China today, a hydraulic plastic injection machine priced from 1 million-1.3 million tons can run smoothly.
You have to spend 1.8 million-2 million tons to have the opportunity to own one—electric plastic injection machine. Making cheap plastic molds is often associated with poor quality – it is a thought ingrained in us.
Products and Services
When buying a cheap product or embroidering an affordable service, people often think of the quality of the product. Plastic injection molding service is cost-effective.
Making cheap plastic molds
However, when making cheap plastic molds, designers and builders know how to optimize improvements and optimize unnecessary costs. We can ultimately make a plastic mold at a low price but still ensure quality. Ensure the requirements that the customer wants.
Factors affecting the price of plastic mold making
One factor that customers are often interested in is how much it costs to make a plastic mold. In this regard, our Plastic Mold Factory would like to advise customers on the factors that determine the cost of a plastic injection product.
Accuracy: This is perhaps the most important factor driving up the price of mold making. A plastic product made with plastic injection molding with a size that requires accuracy of 0.01mm - 0.1mm will cost much more than a product that requires accuracy of 1mm or more.
Products requiring precise mold components
It can be understood as follows; “Products that need to be precise require more precise mold components. To be accurate, mold components require higher precision machining machines.
The more precise the machine, the higher the purchase value… all of these factors drives up the cost of the mold.” Product shape: The simpler the product, the easier it is to make and achieve its intended use.
Products with complex profiles in plastic injection molding
In contrast, for products with complex profiles such as undercuts, threaded products, products that need slides, products that require high gloss, etc.,
The mold structure will be complicated, and it will take a long time to design the mold and process mold. And we have tested many times. This process requires some not small expenses.
Injection molding Product volume:
The larger the product, the larger the mold it is simple rule. Therefore, as the mold material increases, the cost of the mold will also increase.
Above are the two main factors that determine the mold cost. However, if you make a mold, you can rest assured because you don't have to spend a lot of money to make a mold.
Final thoughts on plastic injection molding
In this article, I just mentioned some criteria for evaluation that are within the scope of my understanding.
Currently on the market, several hybrid machines combine the advantages of both of these plastic injection machines.
