| Abstract: | The method of molding in barrel is a new technology of extruding pure UHMWPE pipes continuously on single screw extruder. Its significant advantage is that the pure LrHMWPE tube is extruded continuously and efficiently without any additives. In order to get UHMW-PE pipe with smooth surface, high dimensional accuracy and excellent performance, the tube should be molded precisely by the molding on internal pressure. This paper introduces a continuous pipe-type embryos of pure UHMWPE single-screw extrusion technology, setting temperature field on the UHMWPE pipe pressure, internal stress, strain the mechanism to analyze the molding on internal pressure. Provide a theoretical basis for the design of the equipment. |
