Die-casting process

Die-casting process is the process of unifying pressure, speed and time by using the three elements of machine, mould and alloy. The existence of pressure is the main characteristic of the die casting process to distinguish other casting methods. The pressure casting is a kind of special casting method with less cutting and less cutting, which develops rapidly in the modern metal processing technology. It is to fill the mold with molten metal at high pressure and high speed. The main characteristics of the die casting are high pressure and high speed. The commonly used pressure is tens of MPA, the filling speed (internal gate speed) is about 1680 meters / s, and the time of liquid metal filling die cavity is very short. It is about 0.01g / 0.2 seconds.
