ABSTRACT:
A molded article is produced by a method of compression molding employing a specially shaped billet of thermoplastic material which is positioned at a predetermined location in a predetermined orientation with respect to the mold cavity surfaces of a mold part. In a preferred embodiment, the billet has a generally egg shape and is located adjacent a mold surface defining a small mold cavity region between two larger cavity regions.
