The characteristics of magnesium alloy die casting

Magnesium alloy die casting is carried out in an automatic machine suitable for high pressure. Molten metal is pushed into a two-piece steel die containing one or more cavities, each cavity precisely reversing one or more parts. The mechanical properties of magnesium die castings are generally superior to other casting processes because of the rapid cooling and rapid solidification that occurs when the molten metal comes into contact with a relatively cold steel surface.

In terms of production time, other casting processes can not be compared with magnesium alloy die casting. There are a variety of casting processes that can be used to economically manufacture castings of the required size and quantity. However, magnesium alloy die castings are produced much faster than aluminum or magnesium die castings. In addition, magnesium die castings can be cast to tighter tolerances than any other metal or molded plastic. Net forming or zero machining is the main advantage of magnesium alloy die casting. The repeatability of magnesium alloy die casting is lower than that of smaller parts. 0.001. Only a few other processes, such as aluminum die casting, can achieve the same net shape characteristics and eliminate machining.

Another great advantage of using magnesium die castings is that zinc's excellent casting fluidity, strength and stiffness allows thin-walled profiles to be designed, thereby reducing weight and saving material costs. Magnesium die castings have excellent bearing and wear resistance, providing greater design flexibility and reduced manufacturing costs.
