What is die casting?
Die casting is a casting liquid die forging method. Die casting die forging process is a kind of special casting forging machine to accomplish the process. Its basic technological process is: first metal liquid in low or high-speed casting filling into the mold cavity, die with a moveable type cavity surface, it with the liquid metal cooling process pressure forging blank, both the elimination of shrinkage defects, also make the rough internal Aluminum Die Casting organization to forge the broken crystal. Rough comprehensive mechanical properties are improved significantly.
Aluminum die casting is a method of using high pressure forced the molten metal into complex shapes of hydraulic die within a precision casting method. In 1964, Japan Die Casting Association for die casting is defined as” in the high temperature melting alloy pressing precision molds, in a short time a large number of production of high precision and excellent casting surface”.
The United States said casting for Aluminum die Casting, the UK Pressure Die Casting is called die casting, and the most common domestic industry are familiar with is the Japanese version, called die casting. Through the method of die casting produced in the casting, is called die casting ( Die-castings ).
This material tensile strength, compared to ordinary casting alloy high nearly doubled, for aluminum alloy automobile wheels, frame and hope to use more high strength and impact resistant material production parts, have more positive significance.
