　　Small tricks for aluminum alloy die-casting factories to improve product precision

　　We all know that the formability of aluminum alloy die-casting parts is poor, and it is difficult to ensure the precision of die-casting parts. However, current products have certain requirements for precision. So, as a die-casting part producer, how do aluminum alloy die-casting factories produce high-precision aluminum alloy die-casting parts?

　　Aluminum alloy die-casting parts are currently a popular type of die-casting part, with advantages such as light weight, corrosion resistance, high strength, and high hardness. Especially in the automotive industry, which aims for lightweight, they have gradually replaced products made of other materials. As one of the aluminum alloy die-casting factories, they will answer the above questions next.

　　It is said that because the molten aluminum alloy liquid contains a large amount of hydrogen gas, it is difficult to eliminate it completely during the filling process, and the produced die castings are prone to defects such as porosity. In addition, the metal liquid of aluminum alloy will have a large volume shrinkage during cooling and molding, and it is easy to stick to the mold. Therefore, it is difficult to directly produce high-precision aluminum alloy die castings through die casting.
