Warpage and Structural Analysis of Automotive Trim Based on FFD and CAE in Plastic Injection Molding

Abstract:

In this study, the automotive glove-box-cover was decided as a model, which was assembled on the instrument panel. The material of the cover was Kingfa Sci & Tech Co Ltd, PP+EPDM+20%Talc co-polymer. Firstly, the effects of the process parameters on warpage were examined using FFD. To look for the warpage values, the CAE software Moldflow was used. The significant parameters were found out. Secondly, to determine the distortions of the special points over the top surface of the glove-box-cover, the software Ansys10.0 was used. The structural analyses of the glove-box-cover with different thickness were done in order to determine the performance, and the suggested thickness of the cover was pointed out. At the same time, the strongest and weakest points were found out.
