Zinc Alloy Die Casting
Zinc alloy die casting delivers superior precision and thin-wall capabilities for small to medium-sized metal components. The process offers excellent dimensional stability and surface quality, with faster production cycles compared to other casting methods. Zinc's natural fluidity allows for intricate designs and tight tolerances from ±0.05mm to ±0.1mm.
