Injection molding is a process in which plastic is heated to melt at high temperature, then injected into a mold to form it, and then cooled to complete the shape, and the plastic is solidified and released from the mold. Products usually use rubber injection molding and plastic injection molding. Can be divided into model pressing method.

Rubber injection molding is a way of plastic production. It is a production method that directly injects the model from the rubber machine. The advantage of rubber injection molding is that although it is operated intermittently, the molding time is short and the production efficiency is high.
Plastic injection molding is to use pressure to inject molten plastic into the mold of plastic products to cool down and wait for molding to obtain various plastic parts. There are specialized plastic making machines.
