Chemical Etched Gaskets and Shims From prototyping to Mass Production for US Market

Metal Shims Overview
Our metal shims are precision-engineered thin washers or spacers manufactured through advanced chemical etching technology. They are designed to provide exacting fit, reliable performance, and consistent thickness in assemblies requiring critical tolerances and flatness.

What is Chemical Etching?
Chemical etching is a precision manufacturing process that uses chemical solutions to selectively remove material from metal sheets, creating complex and burr-free parts with high accuracy and consistency. It is ideal for producing thin, delicate parts without altering the material properties.

Metal Shims Features

• High Precision: Tight tolerances with uniform thickness across the entire batch.

• Burr-Free & Stress-Free: No mechanical force or heat, ensuring flat, undistorted parts.

• Wide Material Choice: Available in various metals including stainless steel, brass, copper, and titanium.

• Fast Turnaround: Quick prototyping and production, suitable for both small and high-volume orders.

• Complex Designs: Ability to produce intricate shapes and fine features without tooling wear.
