Title: Method of insert molding auto and truck bumper, rocker panel and chin spoiler parts

Abstract: A paint film laminate is co-molded over a desired plastic substrate to produce an automobile bumper member, chin spoiler or rocker panel part. Along a desired surface of the part, such as, for example, a border between a part surface having one segment covered by paint film and a second segment comprising the exposed substrate, the edge of the paint film is embedded in the plastic substrate along a surface discontinuity such as a recess or ridge so that an aesthetically pleasing sight edge having a desired contour exists along this surface portion. The sight edge is formed during the co-molding process via the provision of an incline or ramp along a desired mold cavity surface. When the co-molded part is installed in its intended application, the paint film edge is substantially hidden from view by the surface discontinuity.
