Squeeze Casting for Disc Brake Calipers

This paper deals with the newly developed technique of the squeeze casting process by using a horizontal die casting machine. Mechanical properties of squeeze castings are superior to those of gravity die casting. The productivity is attainable as high as the pressure die casting by employing the horizontal type of die casting machine for the squeeze casting process. We found also that 0.4∼0.6% Mg addition to A356 alloy improved the squeeze casting performance and that it led to higher tensile strength.

The process has been put into practical use to fabricate disc brake calipers, gear pump casings, brake pedals and so on commercially.
