Abstract：In order to improve the production efficiency and quality of turbocharger housing,the casting process of 1 box and 1 piece was designed by adding risers and subsidies,and the casting process of 1 box and 4 pieces was designed on this basis.The results show that the final casting process of 1 box 4 pieces basically eliminates the shrinkage porosity of the castings,achieves the maximum shrinkage porosity of the castings less than 0.58%,and successfully controls the residual shrinkage porosity in the non-important plane.For the complex thin-walled aluminum alloy parts such as turbocharger housing,the rising can effectively eliminate the shrinkage porosity defect by reasonable setting subsidy and adjustment.
