Abstract

An extrusion die (2) for manufacture of polymeric forms which includes a core section (56) and a cope section (58). The sections define a generally frusto-conical polymer compression chamber (62) uninterrupted by die elements having a single entry port or sprue (50). Means for adjusting the size and volume capacity of the compression chamber (66) are provided to control polymer flow through the orifice outlet (64) of the die. The extrusion die allows the processing of both narrow and broad molecular weight polyethylene materials and other polymerics.
