The pressure is used for metal hot working, and the pressure is the main characteristic of a die casting process to distinguish other casting methods. Pressure casting is a special casting method which is developed faster in the modern metal processing technology and has less cutting and no cutting. The method is a process of filling a casting mold with molten metal at high pressure and high speed, and crystallizing and solidifying the molten metal at high pressure to form a casting. High pressure and high speed are the main features of die casting.

Therefore, in the die-casting process, the manufacturability of the casting structure, the advancement of a die-casting die, the performance and the structure of the die-casting machine, the adaptability of die-casting alloy selection and the normalization of a smelting process are emphasized; the important effects of the process parameters such as pressure, temperature and time on the quality of the casting are more important. Significant control of these parameters should be emphasized during the die casting process.
