Method of making a plural component show face trim part

Method of making a part comprising a plastic substrate material having a show surface with a paint film disposed over a portion of said substrate to reveal an exposed portion of said substrate or said show surface, said method comprising:

• providing a mold cavity having a surface area thereof interrupted by first and second ridge members separated by a space extending along said mold cavity surface area;
• providing a paint film having a pair of edge portions;
• positioning said paint film in said space with each of said edges of said paint film adjacent one of said ridge members;
• and
• injecting molten plastic into said mold cavity and behind said paint film, said molten plastic extending under said paint film along said space and said ridge members, said ridge members, upon contact with said molten plastic and said paint film, forming a pair of channels in said molten plastic with each said edge of said paint film tucked into one of said channels.

Method of making a plural component show face trim part by insert molding of a paint film over a plastic substrate to form a show face side surface of said part wherein a portion of said substrate is exposed on said show surface, said method comprising:

• (a) providing a male mold member including a core portion and a female mold member having a surface defining a concavity therein, said male mold member and said female mold member together defining a mold cavity, said mold cavity including a groove forming member protruding a surface thereof;
• (b) providing a paint film, said film comprising an edge defining an insert portion;
• (c) inserting said film into said mold cavity and positioning said insert portion proximate to said groove forming member;
• and
• (d) injecting molten plastic into said mold cavity and against said film, whereby said film is superposed over said molten plastic such that said insert portion of said film is fixed to said plastic substrate proximate said groove forming member along a boundary between said plastic substrate and said film.

Method of making a plural component show face trim part by insert molding of a paint film over a plastic substrate to form a show face side surface of said part wherein a portion of said substrate is exposed on said show surface, said method comprising:

• (a) providing a male mold member including a core portion and a female mold member having a surface defining a concavity therein;
• said male mold member and said female mold member together defining a mold cavity, said mold cavity including a plurality of groove forming members protruding from said surface of said female mold member;
• (b) providing a paint film, said paint film comprising a plurality of edges with each of said edges defining an insert portion;
• (c) placing said paint film into said mold cavity and positioning each said insert portion individually proximate to one of said groove forming members;
• and
• (d) injecting molten plastic into said mold cavity and against said paint film, whereby said paint film is superposed over said molten plastic such that said insert portions of said paint film are fixed to said plastic substrate proximate said respective groove forming member.
