Die casting process

Because of the advantages of high production efficiency, simple working procedure, high tolerance grade of castings, good surface roughness and high mechanical strength, this method can save a large number of machining processes and equipment, and save raw materials, etc.Therefore, it has become an important part of the foundry industry in China.Die casting process is a process of combining three elements of die casting machine, die casting die and alloy.During die casting, the process of filling the cavity is to unify the process factors such as pressure, speed, temperature and time.At the same time, these technological factors influence each other, restrict each other, and complement each other.Only when these factors are properly selected, adjusted and coordinated, can the desired results be achieved.Therefore, in the process of die casting, attention should not only be paid to the technological properties of the casting structure, the advanced nature of the die casting die, the properties and excellent structure of the die casting machine, the adaptability of the selection of the die casting alloy and the standardization of the melting process, but also to the pressure.Process parameters such as temperature and time play an important role in casting quality.In the process of die casting, we should pay attention to the effective control of these parameters.
