In recent days, aluminum alloys are used for automotive chassis parts construction in order to get weight reduction. Gravity casting among various aluminum casting processes is regarded to have good merit to make complex parts at a lower price and this makes increasing number of car-makers adopt the process for various chassis parts like control arms, knuckles and subframes. In this study, we've tried to develop a hybrid subframe using gravity hollow type sand casting process. FE-calculations for design optimization and casting simulation for process optimization were carried out. Samples cast with A356.0 alloy were tested after T6 heat treatment. Not only mechanical properties of the cast part but actual durability tests were also conducted in a module system to evaluate the acceptance for car application.
