The casting simulation software was used to simulate the mold filling and solidification process of the balance shaft support. Figure 1 shows the solidification process. The casting solidification can achieve sequential solidification. The simulation found that shrinkage porosity may occur at the position indicated in Figure 2. After solidification, the casting was cut and verified (Figure 3). It was found that there was only slight shrinkage porosity in the casting, which met the casting defect control standard. Therefore, it is determined that the internal quality of the casting is qualified.
