| Abstract: | Based on the MAGMA numerical simulation and 3D printing technology, the gating system of cylinder block was analyzed and optimized. The traditional sand mould and cores were replaced by 3D printing cores, and the key sand cores were printed in one-piece sand core. Therefore, the dimensional accuracy was effectively controlled, and the production efficiency was improved. |
