Abstract:
The present invention relates to articles, systems, and methods for injection molding an article. The method includes directing a first shot of molten polymeric material into a mold cavity to form a first part while simultaneously occluding a portion of the gate orifice area with a mold core. Once the first shot is solidified, then the mold core is withdrawn and a second shot is directed into the space previously occupied by the mold core while a portion of the gate orifice area is occluded by the solidified first shot.
