Die casting is a precision casting method that uses high pressure to force molten metal into a complex-shaped metal mold. In 1964, the Japan Die Casting Association defined die casting as "a casting method that uses high-temperature pressure to press molten alloy into a precision mold, producing high-precision parts with excellent surface finishes in a short time." The United States calls it Die Casting, the United Kingdom calls it Pressure Die Casting, while the Japanese term is most familiar to industry professionals in China. Castings produced using this method are called die castings.
The tensile strength of these materials is nearly twice that of ordinary casting alloys, which is particularly significant for components such as aluminum alloy car wheels and frames where higher strength and impact resistance are desired.
