ABSTRACT:
The present invention relates to a two-shot, non-shut-off method of manufacturing a 100% grained trim component for a vehicle. The method includes actuating a tool insert between a mold cavity and a secondary void to form a molded trim component having a groove. A first shot of material is injected to form a first trim element having a grained class-A side. During the first shot, flash enters the secondary void to provide a non-shut-off condition. The tool insert is retracted to define a ditch in the first trim element. A second shot of material is injected to form a second trim element having a grained class-A side, during which time a portion of the second shot enters the ditch to provide a non-shut-off condition. The trim elements are then bonded where a portion the second trim element bonded to the first trim element within the groove.
