Abstract：This study focused on d the injection molding of a specific type of mobile phone shell using Moldflow software.It involved the design of the gating system,flow analysis for both cold and hot runner,and warpage analysis to optimize the molding performance and quality of the plastic component.First,by analyzing four schemes of gate placement schemes,the optimal solution was determined,and a CAE model of the gating system was established based on this analysis.Next,a flow analysis was performed on the cold runner gating system,revealing that,aside from a higher shrinkage index,the other flow ability parameters were reasonable.Further optimization was achieved through systematic packing to reduce the warpage deformation in the Y-direction of the plastic component.Finally,flow and warpage deformation analysis were conducted on the hot runner gating system,which improved various flowability parameters and significantly reduced warpage deformation of the plastic component.This study effectively enhances the injection molding quality and performance of the mobile phone shell,providing essential insights for mold design and manufacturing.
