Optimization of Squeeze Casting Process for Aluminum Alloy Parts

The objective of this project is apply fundamental heat and mass transfer principles to the squeeze casting process to optimize the variables and improve the quality of the castings manufactured by this process. Squeeze casting is a new and developing casting technology suitable for manufacturing light weight structural aluminum castings needed for the production of advanced components in applications such as the automotive industry. Squeeze casting has the advantages of conventional die castings, but also provides weight reduction along with pressure tightness. It achieves mechanical properties with low levels of oxide inclusions and a fine microstructure obtained by rapid solidification. The process also produces the net shape parts that have close final dimensions. This is particularly true for the pressure die casting of aluminum alloys. Because squeeze casting is a relatively new process, much work needs to be done to better understand the fundamentals of the process in order to optimize the variables.
