Title: Positive displacement molding of plastic parts

Abstract

The present invention is a method and apparatus for molding plastic parts and placing and orienting reinforcing fibers within structurally thin sections. More specifically, the method of the present invention is a molding technique wherein positive displacement is applied to incremental sections of a charge (plastic mixed with reinforcing fibers), thereby sequentially forming the desired part and placing reinforcing fibers within structurally thin sections. The apparatus of the invention is a moveable ram that may be tapered and that is in contact with the charge during forming.
