THERMOSETTING
INJECTION

In contrast to the thermoplastic injection moulding process, the thermoset material needs to be heated to cure and thus harden.

The material is preheated to become pasty and deformable.

The material is then conveyed under the effect of temperature by the injection screw towards the front of the screw and barrel assembly and into the tooling.

03.
Injection is carried out under pressure. The temperature of the tooling is higher than that of the screw and barrel assembly. Unlike thermoplastic injection moulding, the part is not cooled but cured in the mould.

04.
The part is pressurised for a certain period and then cured in the tooling. At the end of this curing time, the part can be ejected. A new cycle then takes place.
