ABSTRACT:
A method of manufacturing a foamed plastic article includes disposing a release film on a mold surface of a mold cavity. At least a portion of a bushing is inserted through the release film to form an aperture in the release film. The bushing defines an inlet for foamable material. The mold cavity is then sealed. The foamable material is then injected into the mold cavity through the inlet, wherein the foamable material is conformed to the shape of the mold cavity.
