INJECTION MOULDING EXPLAINED

Injection Moulding is a primary process for producing plastic components. It is fast and used to produce large volumes of identical items from high precision engineering components to disposable consumer goods.

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.

 

INJECTION MOULDING PROCESS

Granules of plastic material are introduced into the injection moulding machine via a variety of conveying systems. The melted plastic material is injected under pressure via a runner system into the cavity. The mould tool that provides the cavity defines the shape of the moulded part. The material is then cooled and finally ejected from the mould as a finished part. The whole injection moulding process then repeats, each cycle producing an identical part.
