What types of automotive plastic moulds are there? Do you understand them?

There are several major categories of automotive moulds, today I will take you to understand about the two classifications in automotive plastic moulds:

1. Injection moulds

Injection moulds are also called injection moulds, and its moulding process is characterised by adding the plastic raw material to the heated barrel of the injection moulding machine after the high temperature hot melt, after the screw or plug push, through the nozzle and mould pouring system into the cavity of the mould, the plastic raw material in the cavity to keep pressure, cooling and finally curing the process of moulding.

2. Compression moulds

Compression moulding process is characterised by the direct addition of plastic raw materials in the open mould cavity, and then the mould closing step, when the plastic material in the dual role of heating and pressure melt, and then the injection moulding machine to a certain pressure, through the pressure of hot molten plastic raw materials will be filled to the cavity. At this time, the molecular structure of the plastic material will produce a chemical cross-linking reaction, slowly hardening and shaping.
