Plastic Injection Molding China-FAQ
People think of China as a low-quality supplier. However, China is undergoing a transformation and Go4 Custom Injection Moulding supplier is leading the way in terms of high quality products and efficient production. the GO4mould factory works 24 hours a day, three shifts a day and our staff are happy to accept overtime, which enables us to complete projects quickly. With a closed-loop production system and proven technology, GO4mould’s prices are more competitive than other global injection moulding manufacturers as well as other Chinese injection moulding companies.
We employ competent sales people who speak fluent English and specialise in both aspects of the business: sales and knowledge of the field. It is well known that understanding the technical part of the business is equally important for injection mould manufacturing projects. Most of our sales people are good at CAD drawing, material selection and mould making processes; therefore, they can communicate their ideas to the engineers without any problems.
While there are thousands of plastic materials available, some are better than others. Choosing the right plastic can affect both the moulding operation and the performance of the final product. GO4 China Mould Makers lists some of the best plastic injection moulding materials for you and where they can be used.
Acrylic: Used to create transparent parts. Examples of this include transparent walls, windows and lighting fixtures. As an alternative to glass, it can be used. Acrylic has high tensile strength, is scratch-resistant and weather-resistant.
Nylon (polyamide): used in the production of mechanical parts such as bearings, gears and bushings. Nylon is a very strong material that only melts at very high temperatures. It is resistant to chemicals and wears well.
Polycarbonate: this is a very durable material, much stronger than acrylic. It can be used for optical discs.
Paraformaldehyde (POM): This is used in the manufacture of automotive and mechanical parts, which are usually made of metal. The material is hard, tough and strong. It is used in the manufacture of products such as ball bearings, tool handles, fasteners and gears. Additionally, it is highly resistant to solvents.
Polystyrene (PS): Both General Purpose Polystyrene (GPPS) and High Impact Polystyrene (HIPS) can be used in the plastic injection moulding process. GPPS is transparent, while HIPS is opaque. Tool boxes and hard cases for power tool bodies are some of the products that can be made from this material.
Polyethylene (PE): This lightweight material is one of the most common materials used in plastic injection moulding processes and is known for its high elasticity, electrical insulation properties and resilience. Although not particularly strong, it is ideal for making a wide range of bottles, waste bins and plastic bags.
Polypropylene (PP): In the food and packaging industries, this material is commonly used. It will not degrade even when washed in hot water. It is tough, flexible and very durable.
Acrylonitrile butadiene styrene (ABS): This opaque material is very tough and resistant to scratches, breaks and tears. It is inexpensive and is often used for keyboards, telephone adapters and plastic shields for wall sockets.
Thermoplastic polyurethane (TPU): This material is soft and pliable, but also very strong. It is used in the manufacture of products that require rubber-like elasticity, such as mobile phone covers, power tools and sports equipment.
Thermoplastic rubber (TPR): This material is a mixture of plastic and rubber, and therefore has the properties of both materials. It is used in products such as headphone cables and medical catheters.
The injection moulding process goes through six stages. These stages must be completed in sequence and determine the quality of the final product.
Stage 1: Closing the mould
This process begins with the placement of the final mould in the plastic injection moulding machine.
The mould is divided into two halves and attached to the platen (steel clamps). A hydraulically driven closing unit pushes the two halves of the mould together. As the molten plastic is injected into the mould, it applies sufficient force to ensure that the mould closes tightly.
Stage 2: Feeding
Once the machine is started, selected plastic pellets or polymer pellets are fed into the hopper, which is a large container with an open bottom. The pellets or granules are moved from the hopper into the drum containing the heating mechanism. The pellets or granules can be fed into the hopper automatically or manually.
The reciprocating screw moves the plastic pellets slowly forward by a sliding and rotating motion. The reciprocating screw is usually hydraulically operated. As the material enters the grooves of the screw, it is heated by friction and using a large amount (10,000 to 30,000) of pressure and heat.
Once the pellets have melted, the melted plastic is quickly injected through the nozzle and fed into the cavity.
Stage 3: Holding pressure
The build-up of pressure encapsulates and holds the molten plastic material within the mould. The holding pressure is always maintained to compensate for any material shrinkage.
Stage 4: Cooling and curing
The plastic is allowed to cool and harden at this point. The molten plastic inside the mould begins to cool as soon as it comes into contact with the inner surface of the mould. As it cools, the plastic solidifies into the shape of the mould.
Stage 5: Mould opening
During the cooling period, the mould remains closed and cannot be opened. Plastics have different thermodynamic properties, which determines the cooling time. Once it has hardened, the platen opens.
Stage 6: Demoulding
The product is removed from the mould by pushing it out of the ejector mechanism of the mould. Sometimes a release agent is sprayed onto the inner surface of the cavity of the mould to aid easy release before the plastic is injected. Once the product has been removed, the mould can be clamped again for the next injection.
The whole cycle may take anywhere between 2 seconds and 2 minutes. This process can be repeated as many times as required to ensure a consistently high quality mould.
When considering the production of a part or product through the plastic injection moulding process, keep the following points in mind.
- Financial considerations
Entry cost: While plastic injection moulding is a cost-effective process, remember that it requires a significant initial investment.
Production quantities: Determine the number of pieces that plastic injection moulding will be most cost effective for you to produce. In addition, determine the number of parts that can be produced for you in order to break even on your investment. Consider all costs – including those associated with design, testing, production, assembly, marketing, distribution and expected sales price. Ensure you make a good profit.
- Design considerations
Part design: Ensure that your final design takes into account the injection moulding process. By simplifying the shape, geometry and number of parts, you can be more successful in creating a high quality product.
Mould design: Ensure that the design of the mould does not lead to a defective product.
- Production considerations
Cycle times: Reduce process/cycle times as much as possible. Carefully designed tools and excellent hot runner technology can reduce times considerably. Even small changes that may seem unnecessary at first can reduce your cycle times and save you a lot of money when producing thousands of parts.
Assembly: Minimise assembly through well thought out design.

GO4 Mould, as a mould manufacturer in China, the first step in manufacturing a product through the injection moulding process is to design the mould. It takes time, skill, and precision to accomplish this.GO4’s design engineers undertake the process of creating the mould. Various computerised versions of the mould design are created. Each version includes patterns, logos, finishes, graphics and layered textures.
Once the final design has been determined, the moulds are made to the exact dimensions of the final product. Moulds are made from steel to ensure they can withstand the heat and pressure associated with mass production.
Moulds can consist of a single cavity or they can have multiple cavities. In multi-cavity moulds, each cavity can be identical or unique to form multiple shapes or parts in a single cycle.
Moulds are made from strong, durable and heat resistant materials such as stainless steel and aluminium. Although aluminium moulds are cost effective, they are not usually suitable for producing large quantities of products or parts with narrow dimensional tolerances.
Yes, we do. Before mass production of products by the plastic injection moulding method, we test the machines used for this process. This is to ensure that all the individual components are in working order and functioning properly. Moulds and polymer compounds are also tested to ensure they are suitable.
A pre-production mould is used to ensure that it is perfect. When it is not, adjustments are made. Testing cannot be skipped since the quality of the final product depends on it.
