Abstract
An automotive trim product is made as follows. A single or multiple layer sheet is extruded so as to include at least one color pigmented and/or metallized layer therein. The sheet is then thermoformed into a three-dimensionally shaped preform via vacuum forming or the like. The preform is placed into a cavity of an injection molding apparatus and heated semi-molten material is injected thereinto. The semi-molten material bonds to the preform in the cavity. After cycling, the molding apparatus ejects a final automotive trim part. Optionally, some processing (e.g. trimming) may be performed following ejection.
