Application of die-casting molds in the automobile industry , magnesium and aluminum alloys are widely used in automobile bodies and different parts. As early as the 1920s and 1930s in Germany, people could see people using magnesium alloys to make different parts. With the development of high-strength magnesium and aluminum alloy materials, they are gradually incorporated into structural parts. Die casting is the main method of producing such parts.

In the past, only small parts were die-cast, including wheels, engine blocks, gearboxes, and pillars. They did not cause significant weight loss. With the development of various die-casting technologies, such as clamping force and injection speed and pressure, it is now possible to die-cast larger parts such as doors and chassis. In short, the introduction of this material has brought significant weight reduction and subsequent fuel consumption reduction.

Automobile lightweighting has been a hot topic for many years. With the increasingly stringent emission standards and fuel-saving measures, people are paying more and more attention. In response to this trend, the automotive industry has gradually replaced steel parts with aluminum parts, thereby stimulating demand.
