The die-casting process is a process in which the three major elements of a die-casting machine, a die-casting mold, and an alloy are organically combined. The process of filling the cavity by the metal during die casting is a process of unifying the process factors such as pressure, speed, temperature and time. At the same time, these technological factors interact with each other, restrict each other, and complement each other. Only by properly selecting and adjusting these factors and making them consistent can we achieve the desired results. Therefore, in the die casting process, not only the processability of the casting structure, the advancement of the die-casting mold, the performance and structural superiority of the die-casting machine, the adaptability of the die-casting alloy and the standardization of the smelting process, but also the pressure, temperature and time should be emphasized. The importance of process parameters on the quality of castings. Manufacture Sand Casting Gravity Casting Die Casting. Effective control of these parameters should be emphasized during the die casting process.
