Product Specification

Product Description

Stainless steel etched shim washers are precision metal components manufactured through chemical etching technology to achieve extremely accurate thickness and dimensions. Compared with traditional stamping or machining, chemical etching allows burr-free edges, complex shapes, and tight tolerances without mechanical stress.

Our stainless steel etched shims are typically produced using high-quality stainless steel materials such as SUS304, SUS301, or SUS316, providing excellent corrosion resistance, strength, and dimensional stability. Thickness can be precisely controlled, making them ideal for fine adjustment, spacing, and alignment in mechanical assemblies.

These precision shims are widely used in automotive systems, electronic devices, aerospace components, precision machinery, and industrial equipment where accurate gap control and reliable performance are required.

Custom sizes, shapes, thicknesses, and surface treatments are available based on drawings or samples. With advanced etching equipment and strict quality control, we ensure consistent quality and stable batch production for global OEM customers.

Technical Features

1. High Precision Thickness Control

Chemical etching technology allows extremely accurate thickness control, ensuring reliable spacing and alignment in critical mechanical assemblies.

2. Burr-Free Smooth Edges

Unlike stamping processes, etched shims are produced without mechanical deformation, resulting in clean edges and consistent dimensions.

3. Complex Shape Capability

Etching technology allows the production of intricate shapes, small holes, and fine patterns that traditional machining processes cannot easily achieve.

4. Excellent Corrosion Resistance

Using high-grade stainless steel materials provides strong resistance to corrosion, oxidation, and environmental wear.

5. Ideal for Thin Metal Components

Etching is especially suitable for ultra-thin metal shims where stamping may cause deformation or burrs.

6. Cost-Effective for Precision Parts

Chemical etching is efficient for medium and large production runs while maintaining high dimensional consistency.
