Metal Shims Overview

Xinhaisen Technology specializes in high-precision chemical etching of metal shims and spacers for industries requiring exact thickness control, complex geometries, and burr-free performance. Our etched shims ensure perfect flatness, tight tolerances, and material integrity, making them ideal for aerospace, automotive, electronics, and industrial applications.

Metal Shims Features

• Absolute Flatness & No Burrs: No tool contact or heat means no mechanical stress, warping, or burrs, ensuring perfect fit and consistent performance.

• Extreme Precision & Complexity: Achieve complex outer contours and internal features (slots, tabs) with tolerances impossible for stamping, especially in thin gauges.

• Rapid Prototyping & Revisions: Digital tooling allows for prototype delivery in days and design changes without costly hard tool modifications.

• Material Flexibility: We etch a wide range of alloys, including spring steels (SK, 301), stainless steels (304, 316), copper alloys (C110, C172), and aluminum.

• Cost-Effective for Low/Medium Volumes: Eliminates the high cost and lead time of precision stamping dies, making it ideal for prototyping and production batches.
