ABSTRACT:
An injection moulding machine has a reciprocable and rotatable screw which is water cooled internally. This enables the temperature of the machine to be precisely controlled. This further enables the required plasticization of the resin granules with limited mixing of the same, so that multi-color effects can be achieved. FIG. 5 shows the waterways in the screw and the rotating supply connections.
