Opitmization of Injection Molding Parameters for Plastic Part Using Taguchi-TOPSIS Method

Name of activity：

Advanced Materials Reserch

Keywords：Injection molding, TOPSIS, Taguchi method, Warpage, Shrinkage

Abstract：This paper reports an simulation study to improve the shrinkage of plastic automobile part by optimizing the injection molding parameters using the Taguchi-TOPSIS method. The Reverse Engineering (RE) and rapid prototyping (RP) technique were used to modeling and createing a prototype model of plastic automobile part. Employing the finite element software, MoldFlow Plastic Insight, the effect of injection parameters on the warpage and shrinkage of plastic part were examind carefully. The simulation results show that Taguchi-TOPSIS method provided an outstanding result for the optimization of injection parameters to produce minimum volumetric shrinkage. The injection parameter of melt temperature was the most significant parameter that influnces the warpage and volumetric shrinkage for plastic automobile part in this study.
