ABSTRACT:
In order to injection mould smooth walled parts from plastics material containing a filler or cellular material a liquid coating material of low viscosity is introduced into the mould by means of the injected plastics material. Under the pushing action of the injected material, the coating material is deposited in the form of a thin film on the walls of the mould. The injection of the plastics material is effected from the lower part of the mould, so that the coating material rises progressively in the mould with the injected material.
