Analysis and Simulation of the Three-Dimensional Injection Moulding Process of Ultra-High Molecular Weight Polyethylene

摘要

Ultra-high molecular weight polyethylene generally canaot be processed by injection moulding because of its high viscosity.In thispaper,theformabilityofGUR-UHMW-polyethyleneisnumerically investigatedduring the injection moulding in an acetabuldt cup.A number of numerical simulation tests have been performed on different acetabular cups to select the most appropriate process parameters and to optimize the injection moulding process.The numerlcal analysis demonstrates that the GUR-UHMW-polyethylene can be processed by injection moulding.
