Feature:
(1) The metal liquid is filled cavity under pressure, and under the pressure of higher crystal solidification, common pressure for 15-100 mpa.
(2) Metal mold filling at high speed, usually in 10-50 meters/seconds, some may be more than 80 m/s, (through the gate into cavity of linear velocity - gate velocity), so the liquid metal filling time is very short, about 0.01-0.2 seconds (different) must inspect the size of the casting and can fill the cavity.
Die casting is a precision casting method, made by way of die casting die casting size tolerance is very small, the surface precision is very high, in most cases, the die casting without turning processing again can assembly application, threaded parts can be directly cast out. From the general of the typewriter and camera, electronic computing devices and accessories and other small parts, and automobile, motorcycle, aircraft and other transportation complex parts are mostly made by die casting method.
The essence of pressure casting is under the effect of high pressure, the liquid or semi-liquid metal with high speed filling type die casting die casting mould cavity, and forming and solidification under pressure and get the casting method.
