Die-casting processes are the process of using three major elements such as machines, molds and alloys, and unify the pressure, speed and time. The presence of metal hot processing and pressure is the main feature of the distinguishing process distinguishability.. Pressure casting is a simple-free-cut special casting method in modern metal processing processes. It is filled with molten metal in a high pressure high speed, and crystallizes to form castings under high pressure. High voltage high speed is the main feature of pressure casting. Commonly used pressure is 10 tribute, the filling speed (inner gate velocity) is about 16 ~ 80 m / sec, and the metal solution fill the mold cavity is extremely short, about 0.01 to 0.2 seconds.
The die-casting process is a process of combining the die-casting machine, die-casting mold, and alloy three elements. The process of metal according to the filling cavity during die casting is a uniform process for the process, speed, temperature, and time. At the same time, these process factors are interacting, mutual restrictions, and complement each other. Only correctly select and adjust these factors, the coordination is consistent, and the expected result can be obtained. Therefore, in the die casting process, it is necessary to pay not only the process of the casting structure, the advancement of the die-casting mold, the performance of die casting machine, the adaptability of the die-casting alloy and the normative structure of the smelting process; more attention to the pressure, temperature and time An important role of process parameters on the quality of castings. These parameters should be valid during die casting.
