Abstract

The filling and solidifying processes of die casting magnesium alloy seat framework were visualized by a finite element method to predict the potential defect position in the seat framework. Based on simulated results

the design of gating system was optimized. The results show that the entrapped-gas and shrinkage porosity （hole） can be obviously decreased in magnesium alloy seat framework during die casting with optimized gating system

greatly improving the quality of die casting seat framework. Furthermore

the shortcomings of conventional die casting process and die design can be effectively relieved and the product period can be shortened greatly.
