Abstract

Flow-3 Dsoftware was carried out to simulate the filling process of casting parts with three type of structures in low pressure die casting（LPDC）process.The influence of the pressurization rate and structure of the castings on the volume of entrained air were investigated.Based on the simulated results

the models with big volume of entrained air and most smoothly filling process were selected and produced in the factory.Tensile samples were prepared and the relationship of the air entrainment and mechanical properties were analyzed.
