Our photo chemically milled metallic encoder disks are precision-engineered components designed for optical and rotary encoders, converting rotational or linear motion into accurate electrical signals for position, speed, and direction detection.

Our advanced photo chemical milling (photochemical etching) process utilizes photolithography and specialized chemical etchants to remove selected metal areas with micron-level precision. This method eliminates mechanical stress and produces no burrs, ensuring sharp edges, consistent aperture sizes, and perfect pattern alignment for encoder applications requiring absolute accuracy.

• Burr-free processing - maintains optical accuracy without deformation
• High repeatability - consistent quality for mass production
• Fine detail capability - micro features down to 0.05mm
• Stress-free manufacturing - no tool wear or mechanical stress unlike stamping or laser cutting
• Rapid prototyping - cost-effective for both small and large production runs

We support complete customization of metallic encoder disks based on your CAD drawings or design files (DWG, DXF, AI, PDF). Our engineering team provides design optimization support for etching efficiency and precision performance.
