Abstract

For the lighting of vehicles structural casting components of aluminum casting alloys are substituted for those of steel or iron. For the manufacturing of large-scale premium quality aluminum castings the developments of a new casting process and a heat treatment process are necessary. The optimum casting design and heat treatment condition for large-scale castings are drawn with the help of Z-Cast software for the casting process analysis in this study. Low pressure sand casting method is applied successfully to produce air bag support components of D357 aluminum casting alloy.
