Custom Etched Stainless Steel Shim Washers & Spacers with Tight Tolerance for the Canada Market

Product Overview
Stainless steel shims are ultra-thin, precision-engineered metal spacers manufactured through advanced chemical etching technology. Designed for applications requiring exact thickness control, uniformity, and reliability, these shims are ideal for high-precision industries such as aerospace, automotive, medical devices, optical systems, and electronic equipment. They serve as critical components for alignment, spacing, insulation, and wear reduction in assemblies where dimensional accuracy is paramount.

Manufacturing Process
Our stainless steel shims are produced using state-of-the-art photochemical etching (also known as metal etching or chemical milling). This process involves:

• Cleaning & Preparation: Stainless steel sheets are thoroughly cleaned to ensure optimal adhesion of the photoresist.

• Photoresist Coating: A light-sensitive photoresist is applied uniformly to the metal surface.

• Exposure & Development: The coated sheet is exposed to UV light through a high-precision photomask, transferring the shim pattern onto the resist.

• Etching: The exposed areas are etched away using environmentally controlled chemical solutions, achieving fine features without mechanical stress.

• Stripping & Finishing: The remaining resist is removed, and shims undergo cleaning, deburring, and quality inspection before packaging.

Product Features

• High Precision: Consistent thickness tolerance down to ±0.01mm, with fine micro-features possible.

• Burr-Free & Stress-Free: Etching eliminates mechanical deformation, ensuring smooth edges and no thermal or structural stress.

• Wide Material Range: Compatible with various stainless steel grades and other alloys.

• Customizable Designs: No-tooling-cost flexibility for custom shapes, sizes, perforations, or complex geometries.

• Rapid Turnaround: Quick prototyping and mass production capable of handling urgent and high-volume orders.
