Magnesium Die Casting of Engine Parts

The principle of magnesium die-casting for engine parts‌ mainly involves using high pressure to inject molten magnesium alloy into a precision mold and forming it through rapid solidification. This manufacturing method allows magnesium die castings to offer a range of significant advantages, including the ability to produce complex shapes, high precision and high quality metal parts. Magnesium alloy die-casting technology is widely used, including but not limited to engine parts, gearboxes, body structures, wheel hubs and other key parts. The application of magnesium alloy die-cast parts not only promotes the lightweight process of automobiles, but also brings higher energy efficiency and lower emissions to the automobile industry.

The choice of magnesium alloy is critical to the die casting process. Different magnesium alloy series have their own characteristics and scope of application. For example, the Mg-Al-Si (AS) series has good creep resistance, high strength, good plasticity and toughness, but poor mold filling performance, and is often used to manufacture engine parts with higher operating temperatures. The Mg-Al-Zn (AZ) series has balanced mechanical properties and casting properties, and is suitable for manufacturing thin-walled die-casting parts with complex shapes.

The advantages of the die-casting process include the ability to produce components with complex shapes while maintaining high precision and quality. This process involves injecting molten or semi-molten metal into a metal mold at high speed and crystallizing under pressure to form the desired part. The commonly used injection pressure is 30~70MPa, the filling speed is about 0.5~50 m/s, and the filling time is 0.01~0.2 s‌.

The principle of magnesium die-casting for engine parts is to inject molten magnesium alloy into a precision mold through high pressure, use the inner cavity of the mold to apply high pressure to the molten metal, and produce complex-shaped, high-precision and high-quality metal parts through rapid solidification molding. This will allow the vehicle to be lightweight, improve energy efficiency and reduce emissions.
