What is magnesium die casting?
Magnesium die casting is a precision manufacturing process used to produce high-quality parts from magnesium alloys. In this process, molten magnesium is injected into a steel mold under high pressure, forming complex shapes with excellent dimensional accuracy and surface finish.
The process begins by melting the selected magnesium alloy in a controlled furnace. The molten metal is then forced into the mold cavity, where it rapidly cools and solidifies. This high-pressure casting method enables the creation of intricate geometries and thin-walled components that are lightweight yet strong, making magnesium die casting ideal for automotive, aerospace, electronics, and industrial applications.
