Process of plastic injection molding
Use of plastic injection molding
Plastic injection molding is the most common and widely used method for the mass production of plastic products around the world because of its convenience and ease of use. Plastic products made using this method include plastic chairs and tables, electronic product covers, disposable spoons and knives, and other cutlery products.
History of injection molding
Plastic injection molding was started by European and American chemists who were experimenting with plastics. Originally done manually and pushed into the mold using Parkesine, it turned out to be too brittle and flammable. John Wesley Hyatt is the official inventor of plastic injection molding, and this process has a rich history with a brilliant spirit.
Injection molding was originally invented to solve the problems that billiard players face abundantly. The 19th-century billiard balls were made of ivory derived from tusks taken from elephants. Celluloid was one of the first plastics used to make billiard balls.
Plastic Injection Molding
Instructions for the procedure
The scientific procedure used to produce plastic products by applying injection molding is very simple. Your plastic melts and is put into a huge syringe. It is then placed in a suitably shaped mold depending on the product being manufactured and allowed to cool for a sufficient amount of time to reach the desired shape. However, the actual process of actual injection molding is not so simple and can be broadly divided into three subdivisions: injection unit, molding section and finally clamp. The plastic pellets are gradually liquefied and gradually injected into the injection unit through a tunnel that is completely melted until it reaches the front of the barrel. When it reaches the mold, it cools and hardens to the desired fixed shape. The mold will then return to the original machine position.
All injection molded parts start with plastic pellets with a diameter of a few millimeters. They can be mixed with certain limited amounts of pigments called “colorants” or up to 15% recycled material. The mixture is then fed into an injection molding machine. Early molding units used a plunger to push down from above. However, the outer area was hot or cold and the melting process did not work properly. The solution to this was a reciprocating screw. This was often seen as the most important contribution that was none other than a revolution in the plastic product manufacturing industry. The screws cause the shear stress necessary to melt the plastic, and the rest of the heat comes from the traditional heater band that surrounds the machine. When molten plastic is injected into the mold, the air is released through the sideways vents. The honey viscosity plastic is so thick that it cannot be released from these vents, which are only a few microns wide.
Engraving witness marks on plastic products is also an important part of marketing. This is because we need to be able to authenticate and verify the authenticity of the product by looking for a line separate from the witness mark. These are created using removable inserts and can prove very helpful in tracking defects.

Many things go wrong in case of compromise in the purchase process. For example, delayed delivery, frauds, low quality, weakness of communication (both on language and technical), and other problems may be encountered. To avoid such frustrations, the following is a process of how a buyer would purchase plastic injection molding from China. Hope this could help you find your best suitable supplier
Identify a Reliable Plastic Molding Manufacturer
Currently, there are many mold manufacturing companies in China. You need to determine which supplier is reliable. Some of the factors to consider include, mold price, quality, quantity, accessory standard, communication, lead times, and the mold design, among other factors.
Using the World Wide Web, you can easily find a wide range of plastic molding suppliers from the internet, sourcing agents, and trade shows, etc.
It is important to contact several suppliers before making a decision on a suitable supplier.
Evaluate the Various Mold/Molding Manufacturers
Conducting market research on the various plastic molding manufacturers helps to find a suitable fit for the business. So how can one evaluate the Chinese mold makers to identify a reliable source?
Sending inquiries helps the evaluation process. You should focus on asking questions that evaluate the core competence of the plastic molding companies.
A good supplier is one that shows interest in your projects, has effective communication, knowledgeable, detail-minded, and honest. The evaluation should target to identify the salient attributes of the supplier, for example, what is advantages do they have, is it suitable for your project? Have they done any similar projects like yours? All of the information will help to make your project smoothly or not.
Information Verification
Not all manufacturers are who they say they are. The customer should be able to verify the plastic molding manufacturer. Some of the information that can be verified include:
- Type of mold parting line
- The type of ejection modes, whether pins are used and the particular locations,
- Surface requirement on the visible surface
- The location and type of gates
Such information helps to verify the mold designs and product appearance. the most important thing is basing on this discussing with each other you will know their communication and technology ability. A supplier that verifies the information and offers samples is reliable.
Analysis of Production Issues that may Arise
A good plastic molding supplier should communicate the issues in advance and concerns that may arise in the production process, and actions are taken to address the issue. A good injection mold company should analyze the current design and offer rational recommendations, we call this DFM report.
Some of the important questions that help identify some of the issues include;
- Have you produced similar molds/products before?
- What were the challenges encountered?
- Can you send your quality control inspection report?
- How do you address the issues that arise?
- Do you offer compensation for compromises?
With all the information, you should already have identified which Chinese molding company to source from.
Firm/Supplier Site Visit
Depending on the quantity of supply sourced, visiting the supplier may be important. For large quantities of plastic molding service, traveling to China should be a basic step. The objective is to analyze samples and evaluate the reliability of the supplier.
Go to their plastic molding company on site to communicate with them face to face, then you will know how the technical skill, English ability, etc. But mostly not always have time to check their mold factory, so we suggest you may ask for a skype video shows if you have no time to visit them.
At SINCERE TECH will take Skype video meeting to show you around our plastic mold and molding factory if you have no time to visit our factory, our sales and project manager speak good English and have the professional technical skill, you will know this during the video shows. if you are interested in our service, you are welcome to contact us.

Importing products from China and Asian nations can be risky and complicated. Contracts are antidotes against the common mistakes and issues that may arise. It is essential for buyers to get into a contract for the following reasons;
- To maintain clarity on product specifications and avoid misunderstandings. The specifications of the product can be easily lost in Skype or mail communication.
- Compensation terms help suppliers to think twice about compromise.
- Contracts help to communicate on how severe your business is
- It helps to avoid delays
The first time you work with a China plastic injection molding company (same to work with your local supplier), you should always make agreements on contracts to avoid scams and fraud. Suppliers who default the negotiations should be responsible for making refunds and necessary compensations.
7.Payment and Delivery
Based on the set agreement, the amount can be paid by one time or two times ( maybe more times). The payment method depends on the agreed strategy. Some companies make payments via Paypal, Skrill, Payoneer, Western Union, Cheque, or other policies. Our standard payment term is T/T wire transfer. If the small amount.

What is a plastic injection mold?
A Plastic injection mold is metal steel that has been made the hollow base apart sharp you want and later filled with a liquid or any other material that can use to your idea plastic products which will last millions of cycles. Some of the material that can be poured into the hollow space of the steel include plastic, metal, glass and even ceramic materials. The liquid is allowed to solidify and the block is broken to retrieve the mold that has acquired the shape of the block. Plastic mold is a custom mold that is using for making custom injection molding parts.
Plastic mold technology
Plastic mold technology is by far the most popular method to manufacture plastic parts in the world today. This process is used for everything from inexpensive commercial plastic products, like disposable eating utensils, toys to the severe environment, highly stressed technical components, like critical parts for automotive and aerospace industries.
You’ll find extensive use of injection molded plastic parts in the electronics world for things like enclosures for cell phones, computers, televisions, and the like, as well as in the medical world where things like syringe bodies, breathing apparatus and a wide range of other life-saving devices are employed. No other process has come to dominate modern manufacturing as plastic molding, and its use increases every year.
Recently, critical steering components for General Motors cars and trucks were changed from stamped and machined steel parts to a plastic molded assembly resulting in a lighter part, at a lower cost, quieter, and more reliable.
What is Plastic Injection Molding
Plastic injection molding is the process of the heating thermoplastic resin to a liquid then shooting it under high pressure into a mold cavity that is the negative image of the desired part, allowing it to get cooling, then opening the mold to allow the completed part to be ejected out from the mold.
In most cases, features can be built into the plastic mold cavity to give the part everything it will need when finished so that no other operations are needed once the part comes out of the mold. Textures, or high polishes, markings, screw holes, lens shapes, and any other features needed in the finished part can be built into the mold so the finished part automatically has these features incorporated.
The advantages of plastic molding
The beauty of plastic moulding is that many parts, even millions, can be made in exactly the same way and will come out the same no matter what. Each piece will have identical features, same dimensions, and physical properties. It is the ideal way to make high volumes because of this consistency. Properly maintained, injection mold can last decades making millions of parts per year. Properly set-up and controlled, the 20 millionth part will be identical to the first part in every measurable way. No other manufacturing process has the potential to operate at this consistency.
Multiple cavities of each part can be built to the plastic injection mould tool, so that each time the mold opens, you make 16 or 32 or 48 or some other multiple of parts for each cycle of the injection moulding machine to really increase the production rate and greatly decrease the cost of making a part.
In some cases several different parts, for instance, a right and left-hand version of an enclosure can be made in a single mold as well to reduce the number of machine cycles required to make multiple parts of an assembly, increasing production and lowering the cost. Injection moulding also offers flexibility not possible with any of the other manufacturing processes.
Injection molding also offers one of the lowest scrap rates of any other manufacturing processes as well. Since no second operations are generally required, no material is cut off and thrown away. It is possible to use a special technique to completely eliminate even the small pathways the plastic flows through to cut the material scrap rate to virtually zero, or often, any plastic removed in the process can be reused by pelletizing it and mixing it back into the fresh plastic resin in closely controlled proportions. These capabilities mean a higher percentage of the raw material becomes part of the finished part than in any other process. Plastic injection molding is highly efficient.

Plastic Injection Molding Technology
What is Plastic Injection Molding
Plastic Injection Molding Technology involves the use of thermoplastic materials to create a range of custom-designed parts for manufacturing. The plastic injection molding technology process entails heating plastic until molten and then press it into a metal cavity mold to obtain the shape. The plastic is quickly cooled, removed, de-spewed and ready for assembly. The material is then cooled, a ready result that depends on the physical properties of the cavity of the mold cavity.
The plastic Injection Moulding process is applied to any plastic product you meet daily. Everything from the bottle cap of non-alcoholic beverages to the dashboard was created in the injection molding process. Even the plastic components that make up the computer you are currently using have been formed by injection.
There are many materials compatible with injection molding – from plastic to metal. Almost anything can be art. Machine types vary in size, shape, and operating costs, allowing for a wide range of customization. As with most products produced in large quantities, plastic or metal products can be made the same way over and over again, which means that the cost of molding is distributed over the total number of parts produced.
This allows you to produce products such as clothes hangers, games and DVD covers at more than the cost of materials, while products with a limited number of products, such as vinyl games or custom artwork, cost much more per piece.
Why use Plastic injection molding Technology
Here are the other benefits of plastic injection molding

- Material Selection: Deep drawing is typically performed on sheet metal, commonly aluminum, stainless steel, or other alloys. The choice of material depends on the specific properties required for the final product.
- Blanking: The process begins with a flat sheet metal blank, which is usually circular or rectangular. The blank is cut from a larger sheet in a process called blanking.
- Placing the Blank: The blank is placed over a die, which is a specially designed tool that defines the shape of the final product.
- Drawing: A punch is used to force the sheet metal into the die, creating a deep-drawn shape. The metal is stretched and formed to take on the contours of the die, resulting in a hollow part with a depth greater than its original diameter.
- Redrawing (if necessary): For more complex shapes or deeper parts, the drawn component may undergo additional drawing operations to achieve the desired final form.
- Trimming: Excess metal, known as the “flash,” is trimmed away from the deep-drawn part, leaving the final product.
The deep drawing process is suitable for producing a variety of shapes, from simple cylinders to more complex forms with irregular geometries. It offers several advantages, including:
- High Production Speed: Deep drawing is a rapid and efficient process suitable for high-volume production.

Injection Molded Parts
Injection molded parts
What is injection molded parts for?
Injection Molded Parts is plastic parts that are produced through plastic injection molding. It is known that plastic is known to be a very versatile and economical material that is used in many applications. Your computer monitor, mouse and keyboard are the examples of Injection Molded Parts.
Injection molded Parts is created by using an injection molding machine, which works by melting plastic pellets, and injecting them into a mold. Related to the case, designing plastic parts is a complex process, and the manufacturing end of it must be taken into account during the design phase. There are three elements of an injection molded plastic part; the nominal wall, projections, and holes and recesses.
The nominal wall as the first element of injection molded plastics refers to the wall thickness. The wall thickness throughout the part should not vary by more than 10 percent. Varying wall thicknesses in the injection molded plastic parts is one of the main causes of flawed product.
How to design injection molded parts
In designing injection molded parts, people usually avoid excessively thick walls, simply because thick walls use more plastic, and are more expensive to produce. However, there is a limit as to how thin the part can be as well. The strength of the part is a function of the thickness, and the final use of the product will determine the desired strength. Some specialized injection molded plastic parts require reinforcement with glass or carbon fibers.
A projection is another element of injection molded parts that projects out of the nominal wall, such as reinforcement ribs. The ribs must not be thicker than the nominal wall, or else sink marks may result.
Recesses and holes are also a major design element of plastic molding parts. The location of any holes or recesses may significantly affect the part’s overall strength. Trying to create a hole in the side of a part is especially challenging, and the need for side holes should be minimized in the initial design.
plastic molding parts
If you need plastic molding parts design or plastic mold making, welcome to contact us, we are mold manufacturer China that offer one top service for plastic injection mold molding service
Besides the three elements of injection molded parts mentioned above, another design factor is the corners of the part. How the plastic enters and fills the mold is of great concern. Because melted plastic is a fluid, fluid dynamics will dictate the design as well, to a large extent.
In this case, the plastic molding parts will flow better during injection if corners are rounded. In the other hand, the plastics will pull against a sharp corner during the cooling process, and a flawed part may result. To result in a stronger part that is less likely to crack or break, creating a low stress design with smooth transitions is a must.
There are two types of materials used in injection molded parts: thermoplastics and thermoset plastics. No matter what type of material is used, it is generally supplied in a granular or powdered format. Leftover and scrap materials from thermoplastics can be recycled, while those from thermoset plastics cannot, due to their chemical transformation during the mixing and curing process.
Types of thermoplastic materials used for plastic molding parts include: polystyrene, acrylonitrile butadiene styrene (ABS), polyimide, polypropylene, polyeththylene, and polyvinyl Chloride (PVC). Meanwhile, thermoset plastics consist of two or more base materials that are mixed together and then the mixture undergoes a chemical reaction to create a new material. Types of thermoset plastics used in injection molding include epoxy and phenolic.
