What is Die Casting?

Oct,08 2022

Pressure casting, referred to as die casting, is a casting method in which molten alloy liquid is poured into the pressure chamber, the cavity of the steel mold is filled at high speed, and the alloy liquid is solidified under pressure to form a casting. Die casting is distinguished from other casting methods by high pressure and high speed.

① The liquid metal is filled with the cavity under pressure, and crystallizes and solidifies at higher pressure, the common pressure is 15-100mpa.
② Liquid metal filling cavity at high speed, usually in 10-50 m/s, some can be more than 80 m/s, (through the gate into the cavity linear velocity – gate speed), so the filling time of liquid metal is very short, about 0.01-0.2 seconds (depending on the size of the casting and different) can be filled cavity.

 

Die casting is a precision casting method. The size tolerance of the die cast is very small, and the surface accuracy is very high. In most cases, the die cast can be assembled without turning, and threaded parts can also be cast directly. From the general camera parts, typewriter parts, electronic computing devices and ornaments and other small parts, as well as cars, locomotives, airplanes and other vehicles of complex parts are mostly made by the use of die casting.
