What is Aluminum Die Casting?

Aluminum die casting including high pressure aluminum die casting is a mature metal forming technology. Molten aluminum alloy is injected into precision molds under high pressure and solidified rapidly. It can form complex aluminum parts in one piece with high efficiency and high precision, widely used in electronic enclosures, auto parts, new energy components, communication devices and home appliance hardware.

Advantages: Aluminum die casting delivers lightweight, high-strength, thermally conductive, dimensionally accurate parts with good corrosion resistance and electromagnetic shielding, ideal for mass production of complex components.
 
Disadvantages: It has high initial mold costs, limited suitability for ultra-thin/fully sealed parts, and cannot process certain high-strength aluminum alloys.
