Casting magnesium automotive components in the low pressure permanent mold (LPPM) process offers unique technical challenges due to the low volumetric heat content and the high hot tear tendency of magnesium alloys. Using its experience producing safety-critical aluminum automotive components with the LPPM process, General Aluminum Manufacturing Co., Madison Heights, Mich., developed filling and solidification simulation models for a magnesium control arm to assist the tooling design and casting process. Simulation analysis results obtained with the company's software assisted with the following aspects of the casting process:
