| Abstract: | Gating systems are designed for die casting of magnesium engine cylinder body by its structure characteristics. The filling and solidifying processes are simulated with finite element software. According to simulation results filling time, solidification time and the distribution and size of shrinkage porosity that may exist in the casting are forecasted. The optimization design of gating system is conducted. |
