Injection Molding
Injection molding is a processing technique for thermoplastics, also known as plastic. Plastic injection molding is an extremely suitable production method for producing larger quantities of plastic products.
The Injection molding process is comparable to high pressure die casting and is suitable for large production series. Often a mold consists of multiple cavities, resulting in a very high production speed. This process is particularly suitable for thermoplastic materials such as PLA, ABS, POM, PE, and PP. In many cases, residual materials can be recycled for new production.
Distinctive appearance
What sets Chinaworks apart is the delivery of plastic molded products that have a surface finish. A surface finish such as chrome plating or painting in a specific color is possible. But also, personalizing your products through screen or pad printing with your company logo or text is possible.

Advantages
- Highly suitable for thermoplastic materials.
- Very high production speed for large production series.
- High shape complexity is possible.
Consequences
- Limited choice in thermosetting plastics, where production costs are often higher.
- Relatively high initial start-up costs due to mold expenses.
Injection molding involves injecting molten plastic under high pressure into an aluminum or steel mold. The plastic solidifies under pressure and is then ejected from the mold. The process is very similar to and is also known as the equivalent of aluminum high pressure die casting. The process is suitable for high complexity shapes, with threads, inserts, and undercuts possible. However, this requires different moving parts to be applied in the mold, which leads to higher mold costs.
The most commonly used injection molding machine is the reciprocating screw machine, in which plastic raw material (granulate) is turned through a heating element with a screw spindle. The plastic reaches a liquid state and is injected into the mold with the screw spindle. Multiple cavities are often used in a mold, allowing multiple products to be made with one injection. The production speed can be very high, making plastic injection molding particularly suitable for large series.
