Why do manufacturers use injection moulding?
Injection moulding allows manufacturers to produce complex shapes that would prove too difficult and costly to assemble. This forces the liquid plastic into every area of the mould. It is, therefore, possible to create intricate designs, confident in the knowledge that they will be replicated in plastic.

What materials are used for injection moulding?
Thermosets and elastomers can also be used for injection moulding, although they are not as widely used. Whilst the majority of moulds are constructed from steel, other metals including stainless steel, copper alloy and aluminium can also be used for specific procedures.
How are parts made in a metal mould?
Once the part for the product has been designed, the metal mould is precision-machined to create the desired shape, either as a single cavity or multiple cavities. The chosen material for the part, usually taking the form of plastic granules, is fed through a heated chamber and forced through a plunger into a hollow mould.
