　　1. The effect of the main process parameters of die casting on the quality of the casting

　　The die casting process is the process of organic combination and comprehensive use of the three major elements of die -casting machines, die -casting molds, and die -casting alloys. The process of filling the metal -filled cavity of the die -casting machine is the process of dynamic balance of pressure, speed, temperature, and time. These process factors not only restrict each other, and complement each other. Only by correcting and adjusting these factors to coordinate them can the expected results be obtained. During the firing process, it not only attaches importance to the processing of the casting structure, the advancedness of the casting, the performance and the excellent structure of the die -casting machine, and the adaptability of the die casting alloy and the standardization of the melting process. It should also pay more attention to the key to the comprehensive performance of the casting of pressure, speed and time, and also directly affect production efficiency and mold life.

　　2. Pressure

　　In the whole process of pressure casting, pressure played a dominant role. The melting metal not only enters the pouring system under pressure under pressure, but also solidifies the forming under pressure. During the firing process, with the movement of the punch position, the pressure also changes differently. This change will have a significant impact on the quality of the casting. Therefore, we must have a emotional understanding of the role and change of pressure during the die casting, which is also the theoretical basis of die casting technology.

　　3. Pressing speed

　　The pressure oil in the casting of the casting cylinder pushes the line speed of the forward punch. Depending on the performance of the die -casting machine, the firing speed can be divided into a slow -to -firing speed and fast -fired speed, or even a multi -level firing speed.
