Sand casting is the most traditional casting method, in which sand is used to make a cavity for pouring to obtain castings
However, the pressure of the molten metal in sand casting is often insufficient, resulting in defects such as dissatisfaction and cold isolation;
As a result, a new casting method was produced: pressure casting, which is die casting.
Artificially provide pressure to enhance the fluidity and filling capacity of molten metal to obtain better quality castings
It is a casting method in which molten alloy liquid is poured into a press chamber, the cavity of a steel mold is filled at high speed, and the alloy liquid is solidified under pressure to form a casting. The main characteristics of die casting that distinguish it from other casting methods are high pressure and high speed.
