The die surface of aluminum alloy die castings and the adhesion of liquid metal can lead to insufficient surface material. The main cause of defects in aluminum alloy die castings is that the surface of the mold cavity is damaged, or the inclination angle of the mold is too small when the mold is in the correct direction, the balance occurs during the ejection process, or the mold is loose. The treatment method of aluminum alloy die castings is to repair the surface damage of the mold in time, trim the mold slope to improve the surface finish of the mold, and balance the ejection force when the ejector rod is adjusted.

When using aluminum alloy die-casting parts, it is necessary to control the casting mold well, so that the mold temperature can reach more than 200 degrees. In the control, it is necessary to precisely control its temperature, so a special mold temperature machine for aluminum alloy die-casting is used. After a period of time, it is necessary to replace the aluminum alloy die-casting release agent in time, adjust the iron content and cooling time of the aluminum alloy reasonably, and modify the inner gate of the finished product in time.
