Chemical Etched Optical Encoder Modulator Coded Disc for Positioning Systems

Chemical Etched Optical Encoder Modulator Coded Disc for Positioning Systems

Product Overview

Xinhaisen specializes in the precision manufacturing of metal encoder discs using advanced chemical etching technology. Our encoder discs are critical parts used in motion control systems to convert rotational position or speed into digital signals.Leveraging our expertise in precision metal etching, we produce high-resolution metal discs that offer superior durability compared to traditional glass or plastic alternatives. From prototypes to mass production, Xinhaisen delivers precision, speed, and consistency for every order.

What is Etching?

Etching, also known as photochemical machining, is a precision manufacturing process that uses chemical solutions to create complex metal parts. Unlike stamping or laser cutting, etching produces no burrs, no heat stress, and perfectly flat parts.Our process uses high-resolution phototools to transfer precise patterns onto metal sheets. The chemical etchant removes only the exposed areas, creating accurate slots and holes. This method is ideal for producing the micro-fine patterns required for high-performance encoder discs.

Product Features

• High Precision – Capable of producing micro slots as small as 0.03mm with uniformity of ±0.03mm for accurate signal transmission.

• Burr-Free & Flat – Chemical etching ensures smooth edges and stress-free flatness, essential for consistent rotation.

• Durable Material – Typically made from stainless steel, our discs resist shock, vibration, and temperature changes better than glass or plastic.

• Thickness Range – Available from ultra-thin 0.02mm up to 1.5mm depending on application needs.

• Fully Customizable – Any pattern, any size, any material. We manufacture according to your CAD drawings.

FAQ

Q: What makes metal encoder discs better than glass discs?
A: Metal discs are much more durable. They resist breaking from shock or vibration, making them ideal for industrial and automotive environments where reliability is critical.

Q: Can you make custom patterns?
A: Yes. We produce encoder discs based on your specific CAD drawings. Send us your design and we will manufacture it precisely.

Q: What is the smallest feature you can etch?
A: We can etch line widths down to 0.015mm and holes as small as 0.03mm, allowing for high-resolution encoder applications.

Q: Do you handle large production orders?
A: Yes. We are equipped for both small prototype runs and ultra-large volume production with fast turnaround times.

Q: How do I request a quote?
A: Simply send your CAD drawing (DXF, DWG, or IGES format) with material and quantity requirements to our sales team.
