OEM/ODM Etched Metal Shims & Spacers for Communication, Medical, Optical Industries

What is Etching?
Metal etching is a precise, subtractive manufacturing process that uses chemical solutions to selectively remove material from metal sheets, creating complex and burr-free parts without altering the material's inherent properties. It is ideal for producing thin, flat parts with intricate designs and tight tolerances.

Metal Shims Overview
Our etched metal washers are high-precision, flat sealing or spacing components manufactured through advanced chemical etching technology. They offer exceptional accuracy, consistency, and design flexibility unmatched by traditional stamping or laser cutting, especially for thin gauges and complex geometries.

Manufacturing Process

1. Cleaning: Metal sheets are thoroughly degreased and cleaned.

2. Lamination: Application of a light-sensitive photoresist film.

3. Exposure & Development: UV light transfers the digital tooling pattern onto the resist, which is then developed to reveal the washer design.

4. Etching: The sheet is sprayed with a controlled chemical etchant, precisely removing exposed metal areas.

5. Stripping & Cleaning: The remaining resist is removed, and parts are cleaned.

6. Inspection & Packaging: 100% quality inspection followed by careful packaging.

Metal Shims Features

• Burr-Free & Stress-Free: No mechanical force ensures smooth edges and no internal stress or heat distortion.

• High Precision & Consistency: Extremely tight tolerances and perfect uniformity across high-volume batches.

• Design Flexibility: Easy and cost-free prototyping; complex geometries (fine meshes, multi-hole patterns, intricate outlines) are simple to achieve.

• Material Versatility: Processes a wide range of metals without tooling wear.

• Rapid Lead Times: Digital tooling allows for faster production turnaround, from prototype to mass production.
