ABSTRACT:
A mold for making a double layer molded product, such as a molded product of sandwich construction or a hollow molded product having a dam within the mold cavity adjacent its gate. The dam projects in a direction transverse to that in which the inner-forming material is injected, and a gap is defined between the dam and the walls of the cavity. With this configuration, the core thickness of the molded product of sandwich construction, or the skin thickness of the hollow molded product, are made uniform.
