China OEM Brass Machined Parts Pricelist - Die casting process – Mestech

Metal die casting process is a process of unifying the pressure, speed and time by using the three elements of machine, mould and alloy. For metal hot working, the existence of pressure is the main characteristic of die casting process which is different from other casting methods. Pressure casting is a special casting method with less and no cutting, which has developed rapidly in modern metal processing technology. It is a process of filling the mold with molten metal under high pressure and high speed, and forming the casting by crystallization and solidification under high pressure. High pressure and high speed are the main characteristics of die casting. The commonly used pressure is tens of megapascals, filling speed (inner gate speed) is about 16-80m / s, and the filling time of metal liquid in mold cavity is very short, about 0.01-0.2s. Metal die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity and core is made using harden steel dies which have been machined into shape and work similarly to an injection mold during the process. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.
