What is squeeze casting?
A. Squeeze casting is a recently introduced high-pressure casting process which, through the use of very large gates and high hydraulic pressure, can cast liquid metal with a minimum of trubulence or gas entrapment. The result is a porosity-free, heat-treatable component with thick walls capable of surviving the critical functional testing essential for structural automotive parts. Production costs will be higher than conventional high-pressure die casting, but squeeze-cast parts have qualified for replacing permanent mold and iron castings in high strength applications. Most production to date has been made with aluminum alloys. The number of casters utilizing squeeze casting machines is relatively limited.
