Abstract

See full text

An apparatus and method for producing defect-critical articles from a molding resin comprising at least 98% clear polymer and additives including a heat stabilizer and a UV blocker in an injection molding machine. According to the apparatus, there is provided an injection molding machine in combination with a molding resin. The injection molding machine's resin delivery assembly is made from a powder metallurgy formed into solid non-coated parts having a Chromium-Vanadium (Cr/V) blend. As the molding resin interacts with the resin delivery assembly, the resin only contacts the solid non-coated parts whereby the resin experiences less degradation and provides improved quality for the defect-critical articles. The method includes the steps of plasticizing, injecting, and cooling. During the plasticizing and injecting steps, the molding resin only contacts solid non-coated parts made from a powder metallurgy material containing a Chromium-Vanadium (Cr/V) blend thereby producing reduced defect articles.
