This article takes the shrinkage defect encountered in the development of an impeller die casting used in the vacuum pump as an example to explain how to find a better solution by CAE simulation to eliminate the shrinkage defect of the die casting so that the time and cost of modification of the mold by trial and error can be reduced.
