US 5,919,324 A · Method of securing decorative insert to underlying plastic skin for trim panel

Abstract

An improved method of forming a vehicle trim part includes the initial step of securing an insert to a vinyl skin in a vacuum mold. The cloth insert is attached to the outer face of the skin, and the two are then placed into a foam mold as a single preform. In this way, if the cloth is improperly connected to the skin, the part can be identified as scrap before foam is injected to complete the part. Once the preform is moved into the foam mold, foam is injected behind the part. Since the preform is positioned within the mold as a single part, the invention more accurately positions the insert and skin relative to the mold prior to foam injection. Again, this improves the quality and appearance of the vinyl part.
