摘　　要：介绍超高分子量聚乙烯(UHMWPE)的特性及熔体流动特点,分析了大型UHMWPE注塑机的构造原理及应用。阐述了大型UHMWPE制件的注射成型工艺,以及大型UHMWPE注塑机在生产效率和原料利用率上的优势。其生产效率可比传统加工方法提高6～7倍,原料利用率由原来的55%左右提高到80%～90%。The characteristics of ultra-high molecular weight polyethylene (UHMWPE) and its melt flow was introduced. The large injection machine for UHMWPE and its application was analysed. The injection moulding of UHMWPE large parts and the advantages of using large injection machine on improving production efficiency and utilization ratio of raw material was stated. The production efficiency by using large injection machine was 6-7 times high than that by using traditional moulding method, and the utilization ratio could raise from 55% to 80%-90%.
