A small housing shell serves as the housing for a power device,and the castings are not allowed to have defects such as shrinkages,slag pores,and sand inclusions,and the organization is dense.In order to reduce the quality risks after the trial production,five casting process solutions were designed,and the filling and solidification processes of the housing shell were analyzed using computer numerical simulation technology.The optimal process solution was determined and validated through production.The results showed that scheme 5 was the optimal process solution.The inner wall of the housing shell was increased by 0-7 mm of allowance,and 20 mm thick conformal chill was placed to obtain a shrinkage-free,dense casting.
