ABSTRACT:
A method of molding a composite structure of a polymeric preformed skin with tightly radiused features and a polymeric foam body is provided. The method includes providing a mold cavity having a first edge; placing the preformed skin in the mold cavity with a preformed first edge of the preformed skin adjacent to the first edge of the mold cavity; heating the preformed skin adjacent the first edge; exposing the first edge to a vacuum to reform the preformed skin first edge to be adjacent the mold cavity first edge and injecting a foam polymeric material into the mold.
