ABSTRACT:
A molding method for molding a shaped plastic trim panel from a wet moldable composite includes a blade for trimming the molded plastic trim panel while it is still in the molding apparatus. The lower mold member has an annular severing slot and annular clamping shoulders inwardly and outwardly of the severing slot. The upper mold member has an annular slot that is aligned with the severing slot of the lower mold member and annular clamping shoulders on either side of the slot. These shoulders cooperate with the clamping shoulders of the lower mold member to clamp the margin of the molded plastic trim panel that is shaped in the molding members. An annular cutting blade having a serrated cutting edge disposed in the slot of the upper mold member moves down vertically into the severing groove to cut through the clamped margin and trim the molded plastic trim panel.
