Laptop Chassis

Magnesium alloy die-cast laptop chassis are precision-engineered frames and covers that provide structural rigidity, lightweight support, heat dissipation, and electromagnetic interference (EMI) shielding. Manufactured using high-precision magnesium alloy die casting, these chassis deliver high dimensional accuracy, mechanical strength, and premium feel while minimizing device weight. They are widely used in ultrabooks, gaming laptops, professional notebooks, convertible laptops, and high-end thin-and-light devices, where durability, heat management, and lightweight design are critical. Application Fields: Ultrabooks and thin-and-light laptops, gaming and high-performance notebooks, convertible 2-in-1 laptops, business and professional laptops, high-end multimedia laptops.
