Magnesium Thin-Wall Structural Casting with High Vacuum
Control Focus:
We precisely control melt quality, high vacuum levels, and intensification pressure to eliminate internal defects. This ensures pressure integrity, allows for T6 heat treatment, and meets strict strength-to-weight and EMI shielding standards for aerospace and high-end electronics.
Process Technology:
Using closed-chamber vacuum technology (cavity pressure <50 mbar), we achieve clean filling of thin walls (down to 1.0mm). A multi-stage injection profile ensures laminar flow, followed by immediate high-pressure intensification (>800 bar) and pulsed mold cooling. This yields dense, fine-grained components with superior mechanical properties and stability.

Our Magnesium Die Casting Parts
Why Choose Magnesium Alloy?
Magnesium die casting offers an excellent balance of strength, precision, and lightweight performance. As one of the lightest structural metals, magnesium alloys allow for complex, thin-walled parts with high dimensional accuracy and outstanding surface quality. They provide excellent heat dissipation, electrical conductivity, and vibration damping—ideal for automotive, electronics, and aerospace applications. Fully recyclable and cost-efficient, magnesium die casting helps manufacturers reduce weight, improve performance, and achieve sustainable production goals.
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.
