Chemical Etching Micro-Thin Optical Encoder Discs 0.05-0.4mm Thickness

Encoder Discs Overview

Encoder discs are critical components in optical and magnetic encoders, used to convert rotational position and speed into digital signals. Xinhaisen manufactures high-pcision metal encoder discs with exceptionally fine patterns, ensuring accurate and reliable motion control in various demanding applications.

Manufacturing Process

We produce encoder discs using advanced photochemical etching. This subtractive manufacturing process allows for burr-free, stress-free, and highly precise patterns without altering the material's properties, making it ideal for high-tolerance, thin-metal parts.

What Is Etching?

Etching, also known as photochemical machining or chemical milling, is a subtractive manufacturing process that uses chemical solutions to precisely remove material from metal sheets. The process involves:

• Photoresist application: A light-sensitive film is applied to the metal surface.

• Exposure & development: A digital pattern is transferred onto the coated metal using UV light.

• Etching: Chemical solutions dissolve unprotected areas, leaving precise patterns.

• Stripping & finishing: The remaining photoresist is removed, and optional finishing treatments are applied.

This method produces burr-free, stress-free components with exceptional accuracy, making it ideal for encoder discs that require intricate patterns and tight tolerances.
