The injection moulding machine consists of a heated barrel equipped with a screw that melts the polymer. The polymer is injected by high pressure into a mould that defines the shape of the moulded part. Then the part is cooled to form the solid object. The mould is opened and the object is discharged.

The mould can be uses to manufacture one part in a repeating process or incorporating multi cavities many components can be manufactured on the same tool repeatedly with a single injection.
