High pressure die casting process
In this process, the liquid metal is injected at high speed and high pressure into a metal mold. A schematic view of high pressure die casting is given in Figure.
This equipment consists of two vertical plates on which bolsters are located which hold the die halves. One plate is fixed and the other can move so that the die can be opened and closed. A measured amount of metal is poured into the shot sleeve and then introduced into the mould cavity using a hydraulically-driven piston. Once the metal has solidified, the die is opened and the casting removed. Compared to Gravity die casting, both the machine and its dies are very expensive, and for this reason, high pressure die casting is economical only for high-volume production.
