What does plastic injection moulding involve?

Plastic injection moulding is a simple, highly repeatable process that’s well suited to medium and large production runs. The plastic injection moulding process involves small granules of plastic being melted under pressure. When the molten plastic is soft enough to be moulded, it is injected into the cavity of a bespoke mould and, as it cools, it takes on that exact shape. Once completely cool, the mould is opened, and the plastic component is released.
