Based on the casting structure

two casting systems were designed and simulated by ProCAST software. The filling process

solidification process and the reason and location of shrinkage were analyzed

then a optimized gating system was presented and the die casting process was optimized by adding cooling system.The result show that the defect of shrinkage is decreased obviously with optimized casting process. The actual product was produced with absence of cold shut or crack in the casting surface

meeting requirement.
