In comparison to compression or transfer moulding, rubber injection moulding generates products with a shorter cycle time. Rubber injection moulding allows for the creation of customised shapes with minimal waste or flash. Before being pressed into cavities, the material is heated. This lowers the material's viscosity, making it easier to flow into the cavities.

The uncured rubber is extracted into the machine via a screw feeding mechanism during the rubber injection moulding process. The screw feeder feeds in precisely the right amount of material to make the appropriate number of components. Rubber is fed into a heated barrel from a hopper, then forced into a heated chamber by a screw-type plunger.
