Injection Moulding Process

There are several processes of moulding plastic into useable shapes, each method has its own benefits and requires specific expertise and skill to execute. The injection moulding process is one of the most widely used and counts for a significant proportion of all plastic products in the UK. 

There are fundamentally six steps to the injection moulding process; clamping, injection, dwelling, cooling, moulding opening and ejection. We've explained each of these steps in more detail, follow the link, the Injection Moulding Process to read more. 

The injection moulding process in short; Plastic granules are melted at high temperatures until soft enough to be injected under the pressure to fill a mould. After the plastic moulding has cooled and hardened the injection mould opens releasing the part. The whole injection moulding process then repeats.
