Housing Die-Casting and its Process Based on Numerical Simulation

Mould filling and solidification of aluminum alloy housing in die casting were simulated by the casting simulation software. Distribution and change of velocity field and temperature field were visualized. The optimized processing parameters were obtained with pouring temperature at 600°C and pre-heated temperature of mould at 180°C as well as injected velocity at 2.5m/s. The qualified aluminum alloy housing and the dense microstructure were successfully produced by adopting the optimized processing parameters, which is proved by the actual production.
