Die casting is a precision casting method that uses high pressure to force molten metal into a metal mold with complex shapes. In 1964, the Japan Die Casting Association defined die casting as "a casting method that presses molten alloy into a precision casting mold at high temperature, and mass-produces high precision and excellent casting surface in a short time". The United States calls die casting Die Casting, the United Kingdom calls it Pressure Die Casting, and the most familiar domestic industry is the Japanese term, called die casting. Castings made by die casting are called die castings.
