Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars.his process is actually an injection moulding process performed twice and therefore has a much smaller margin of error. In the first step, the base color material is moulded into a basic shape, which contains spaces for the second shot.
Plasticising and melting temperature.
