Injection molding

PREPARATION

The plastic material (thermoplastic polymer) is received in the form of granules. For some applications, additives such as colourants can be mixed with the base material. The plastic material is dried with a drying process to remove the moisture present.

INJECTION

The plastic material is transferred and then softened in the revolving cylinder using a heated worm. Injected under high pressure, the material fills the mould cavities via the feeders at a temperature below the transformation temperature. In order to limit materials shrinkage during its cooling, a constant pressure is maintained. Once the cooling circuits have allowed the part to cooled, it is ejected from the mould.
