Precision Instrument Components

Zinc alloy die-cast precision instrument components are designed for applications requiring dimensional stability, high surface accuracy, and mechanical strength. These components are widely used in measurement devices, medical instruments, laboratory equipment, and optical systems. Zinc’s excellent castability and fine-grain structure allow for intricate details, thin walls, and tight tolerances, making it ideal for precision-grade mechanical parts. Application Fields: Measurement instruments, optical devices, medical diagnostic tools, laboratory testing equipment, and control instrumentation.
