Abstract: Aiming at the shrinkage,grain size inhomogeneity in the casting process of aluminum alloy piston,the professional casting software Procast was used to make numerical simulation research on the piston casting process. Orthogonal experiment method was investigated three process parameters of pouring temperature,casting speed,mold temperature.The numerical simulation results were evaluated from several aspects,such as the grain size,shrinkage porosity distribution and filling rate. The results indicate that the optimal combination of process parameters is 700 ℃ pouring temperature,0.3 kg/s casting speed,and 150 °C mold temperature. The numerical simulation of ZL108 aluminum alloy piston casting process provides theoretical guidance for uneven thickness complex parts casting molding,reduces the cost and time of the part design process optimization.
