Improved methods of superposing a film laminate over a plastic substrate and fused film-plastic parts made thereby. Improvement in traditional techniques is provided by preforming the film laminate proportionately relative to the size and shape of the underlying plastic substrate whereby improved gloss consistency of the fused film-plastic part is observed. The film laminate is preformed by shaping it over a pattern block wherein the film laminate is provided with an inner height and inner face width. The inner height of the film laminate is less than the height of the plastic substrate while the inner face width of the film laminate is greater than the face width of the plastic substrate. The film laminate is next positioned in a mold cavity wherein a molten resin is injected thereby forming the plastic substrate and fusing the film laminate thereover.

[ What is claimed is:] [1.] An method of making a plastic part by insert molding a film laminate over a plastic substrate, said method comprising:providing a mold including a mold cavity defined by a male mold member including a core portion thereof and a female mold member having a concavity therein, said concavity having a concavity width and a concavity depth, said concavity width and said concavity depth, together, defining a cavity surface;preforming a film laminate to provide said film laminate with opposed re-entrant flaps and an outer film face width that is greater than said concavity width and a depth that is less than said concavity depth;positioning said film laminate in said concavity so that said film laminate is frictionally fit within said concavity at a depth which is less than said concavity depth;closing said mold to position said film laminate including said opposed re-entrant flaps within said mold cavity; andinjecting a prepolymer into said mold cavity to form a plastic substrate whereby said film laminate is deformed in said mold to conform to said cavity surface in superposition to said plastic substrate.
