Abstract
A method and assembly for forming a multi-shot panel for a vehicle including the steps of providing a mold and forming therein a main body of the panel from a first rigid material, the step of forming the main body further including forming a multi-sided recess. The rigid material is transferred to a second reconfiguration of the mold for forming thereupon at least one second softer material. The panel is then transferred to a third reconfiguration of the mold for forming the heat deflecting shield. Alternative, a two shot injection molded panel can be removed from the mold and a previously formed heat deflecting shield can be attached along edges of the main body defining the multi-sided recess. In either variant, locking features are designed into the interface geometry between the heat deflecting shield and rigid main body.
