Injection Moulding

Injection moulding: Plastic granules of the thermoplastic materials are fed into the hopper (2).

A plunger forces the plastic along the machinebarrel (2) where they are melted by the heaters and compacted by the torpedo (3).

The softened polymer is then forced into the mould where it solidifies.
