Injection moulding in a nutshell

Injection moulding is capable of producing high volumes of parts in a short amount of time and the injection moulding process involves several steps.

Material is fed into a plastic injection moulding machine where it is heated, mixed, and forced into the mould cavity where it cools and hardens to the configuration of the cavity.


A Plus Plastics is leading the Australian plastics industry in automation, utilising robotics to minimize labour costs in a forever tightening manufacturing market. Our 14 machines utilise either 3 or 6-axis robots to extract parts from the machines, which enables our skilled operators to often work on 2 or 3 machines at one time. Our robots also guarantee consistency of cycle time, ensuring we can give our customers the most competitive price.
