| Abstract: | The filling pressure curve of a typical thin-wall cylinder casting in exactitude forming was analyzed by numerical simulation, the optimized non-linear differential pressure curve with the change of cross-section was obtained, which realized that the molten metal filled the mold in calm state.The results show that the cylinder casting is high-quality. |
