Description

Technical field

[0001] The invention relates to an aluminum alloy die-casting process method, in particular to a process method suitable for reducing the precipitated pores of aluminum alloy die-casting parts. Background technique

[0002] During the die-casting production process, when the aluminum alloy solidifies from a liquid to a solid, the hydrogen dissolved in the aluminum alloy will precipitate to form hydrogen gas, and the hydrogen gas will remain inside the casting to form holes. Cut open detection, the inner wall is smooth and has metallic luster, which will exist anywhere in the casting. The existence of precipitated pores in aluminum alloy die castings affects the properties of castings mainly in that it can reduce the density of the casting structure and reduce the mechanical properties. Contents of the invention

[0003] In order to solve the problem of a large number of precipitated pores in aluminum alloy die castings, our company has undergone a large nu...
