Abstract

By using the software Flow-3D

the filling process for aluminum alloy valve cover in die casting and oxides inclusion in ones were simulated. Based on the simulated results

the gating system was optimized to effectively eliminate oxides inclusion in aluminum alloy valve cover. Ingate position has greatly affected the filling morphology and oxides inclusion. Optimization of gating system can reduce inclusion and be favorable for improving castings quality. Computer simulation can provide a reference for evaluation and optimization of gating system.
