Method of insert molding auto and truck bumper, rocker panel and chin spoiler parts, and parts made thereby

摘要

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 (8), such as, for example, a border between a part surface having one segment covered by paint film (9), and a second segment comprising the exposed substrate (14), the edge (12) of the paint film is embedded in the plastic substrate along a surface discontinuity such as a recess or groove (51) 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 (12) is substantially hidden from view by the surface discontinuity (51).
