Detailed manufacturing process of aluminum alloy die castings

Aluminum die casting is to use pressure to create the mold shape you need. Usually, liquid substances are poured into the mold to produce items that meet your needs. Aluminum die casting is widely used, including valve rocker arm, power accessories, motor end cover and other parts.

The common basic processes of die casting aluminum are annealing, normalizing, quenching and tempering. First of all, the purpose of annealing is heating. According to different materials, choose the appropriate temperature to achieve the desired effect. This method is mainly to ensure that the material can have a faster cutting function. Secondly, quenching is the high-temperature treatment of the material. When the material rises to a certain temperature, it is cooled by water or other inorganic salt liquid, so as to achieve the effect of making the material more solid. However, this method will also make the steel brittle. In order to reduce the brittleness, tempering is derived, that is, put the quenched material into an extremely high temperature environment of 650 degrees and then cool it, so as to achieve the desired hardness.

Stainless steel ball is a kind of device with bright surface, no rust scale, round or cylindrical. It is usually divided into pre polished and unpolished cutting pills. These two cutting pills have different shapes, but they can play the role of polishing treatment. Therefore, they are often used for wire drawing, removing impurities on the surface of objects, polishing and so on. At the same time, this kind of object is often used in non-ferrous metal die casting, mechanical manufacturing and the treatment of surface impurities of hardware devices. This treatment is also a common and easy to use operation method. The stainless steel ball is used to rub the surface of the object, so as to polish the oxide layer and burr. And the uneven and rough surface makes the surface of the instrument smooth and free of dirt.

Aluminum die-casting aluminum and aluminum materials can reduce human resources and meet the requirements of green environmental protection. The important thing is that its flow performance can meet all kinds of requirements and manufacture all kinds of mold products. Therefore, it is also one of the most popular choices in the market.
