Xinhaisen provides specialized metal etching services with over 13 years of expertise in precision encoder disc fabrication. We manufacture custom stainless steel encoder discs according to your exact design specifications with ±0.01mm accuracy for industrial automation, robotics, and motion control applications.

Encoder discs (code wheels) are critical components in optical and magnetic encoders that convert mechanical motion into digital signals through precision-etched patterns.

1. Material Preparation: Clean and degrease metal sheets
2. Photoresist Coating: Apply UV-sensitive resist
3. Exposure: Transfer design patterns via photomask
4. Development: Remove unexposed resist to reveal etching areas
5. Etching: Immerse in etchant to dissolve unprotected metal
6. Strip & Clean: Remove residual resist and polish surfaces
7. Quality Control: Validate dimensions, conductivity, and surface finish
