SQUEEZE CASTING:
It was first developed in Russia. It is a combination of casting and forging process. First the punch and die are separated. The furnace holds the liquid metal at a requisite temperature. Then the metal is put into the die cavity and the punch is lowered to its place forming a tight seal. The metal is under a pressure of 50 to 140 mpa and looses heat rapidly because of the contact with the metallic die. Once the casting is solidified, the punch is retracted.
Adv: very low gas entrapment.
Lower shrinkage cavity.
Lower die costs.
High quality surface.
Application: Mg, Al, Cu alloy
