| Abstract: | According to the features of high pressure die casting, low pressure die casting and permanent mold casting, a multi-cycle and multi-stage numerical simulation system has been developed successfully. Some key problems, such as simulation of cooling process, accurate filling modeling of multi-cycle process, have been solved properly. The actual application shows that the technology can precisely simulate the process of high pressure die casting, low pressure die casting and permanent mold casting, and can better analyze cooling process, thus can control quality efficiently, improve production efficiency and guide production. |
