Advantages
The electronics industry is a high-tech sector that integrates precision manufacturing, materials science, and functional design. As electronic devices evolve towards miniaturization, lightweighting, high performance, and efficient heat dissipation, extremely high demands are placed on the precision, strength, and thermal conductivity of metal components.
Casting plays a vital role in the electronics industry, enabling the one-step molding of complex structures with high dimensional accuracy and excellent surface quality. Its applications range from electronic component brackets to device housings, providing critical support components for 5G communications equipment, industrial control systems, smart terminals, and electronic modules in new energy vehicles.
