Aluminum alloy die casting process

The four basic processes of industrial production of die-casting aluminum are quenching, quenching, quenching and tempering, which are called “four fires” in die-casting. In the whole process of die casting, quenching and tempering are closely related, and both are indispensable.

According to statistics, quenching is to better heat the workpiece to an appropriate temperature. According to the selection of different materials, the die-casting is slow cooling, and the internal structure of the metal material has been closely balanced. Normalization is to heat the workpiece to a suitable temperature and cool it in air. It is mainly used to enhance the cutting effect of raw materials, and can also be used as deep processing die casting for some parts that do not require high temperature. Quenching is the heating and heating of the workpiece, in water, or by other carbonate aqueous quenching substances in rapid cooling, through this whole process, the manufactured stainless steel sheet will be hard, but it will also make the steel brittle. In order to better reduce the ductility of the steel plate, hardened iron castings can be stored for a long time below 650 degrees Celsius, above a certain temperature, and then refrigerated, which is called tempering.

The use of aluminum die-casting aluminum and aluminum profiles has excellent fluidity and ductility, so it can make various shapes complex, die-casting, and difficult to apply aluminum alloy profiles and aluminum alloy castings. The production capacity of the forging machinery is greatly reduced, the labor efficiency is greatly reduced, and the power engineering and metal composite materials are saved.
