ABSTRACT:
A mold assembly for forming a multi-shot molded part includes a mold system defining a mold cavity, and a retracting member disposed in the mold system selectively movable between extended and retracted positions in the mold cavity. A first molding material is injected in the mold cavity when the mold system is in a configuration with the retracting member in the extended position, forming a first portion of a molded part including a thin wall portion. A second molding material is injected in the mold cavity when the mold system is in another configuration with the retracting member in the retracted position, forming a second portion of the molded part and providing open cavity portions adjacent both surfaces of the thin wall portion. The second material penetrates the thin wall portion, filling the open cavity portions and forming a connection between the first and second portions of the molded part.
