Simulation Study on HPDC Process for Automobile Part with Aluminum Alloy

Abstract:

In this research, in order to optimize casting design of an automobile part (Gear Box), Computer Aided Engineering (CAE) was performed by using the simulation software (Z-Cast). The simulation results were analyzed and compared with experimental results. During the filling process, internal porosities caused by air entrap were predicted and reduced remarkably by the modification of the gate system and the configuration of overflow. With the solidification analysis, internal porosities caused by the solidification shrinkage were predicted and reduced by the modification of the gate system. For making better permanent High Pressure Die Casting (HPDC) mold, cooling systems on several thick areas are proposed in order to reduce internal porosities caused by the solidification shrinkage.
