The rear axle housing casting was designed by using of three-dimensional modeling software together with gating and risering system and mould. The numerical simulation on solidification process was carried out using Huazhu CAE software. Through the comparison of liquid phase dynamic distribution course during solidification process under different casting technical conditions, various tendencies of shrinkage defects forming can be forecasted. The shrinkage distribution and technical yield of the castings under different casting processes were compared, and the foundry technology was improved and optimized. As thus, defects of castings were eliminated and production period was shortened by putting forward improved technology into production.
