Customized Chemical Etching Metal Shims from Prototype to Mass Production

Customized Chemical Etching Metal Shims from Prototype to Mass Production

Metal Shims Overview

Our metal gaskets are precision-etched sealing components designed to provide reliable performance in various industrial applications. Manufactured with tight tolerances and consistent quality, they ensure effective sealing and long-term durability.

Manufacturing Process
Utilizing advanced chemical etching technology, we produce gaskets with high precision and complex geometries without introducing mechanical stresses or burrs, ensuring perfect flatness and dimensional stability.

Metal Shims Features

• Precision Engineering: Manufactured with tight tolerances (as precise as ±0.01mm), ensuring a perfect fit and reliable seal every time.

• Burr-Free & Smooth Edges: Our chemical etching process guarantees clean, smooth edges without burrs or stress, which is critical for effective sealing and preventing leakage.

• Complex Design Capability: We can easily produce intricate geometries, multi-hole patterns, and custom shapes without the high cost or lead times of hard tooling.

• Material Versatility: We etch a wide range of metals, including Stainless Steel (304, 316), Copper, Aluminum, and Nickel Alloys, allowing you to select the ideal material for corrosion resistance, conductivity, or temperature tolerance.

• Excellent Flatness & Consistency: The etching process ensures uniform material thickness and exceptional flatness across the entire part, crucial for even pressure distribution and sealing.

Metal Shims Applications

• Automotive Systems: Used in engines (head gaskets, seal plates), transmissions, fuel systems, and sensors, providing resistance to high temperatures, pressure, and automotive fluids.

• Electronics & Telecommunications: Acting as EMI/RFI shielding gaskets, insulating spacers, and seals in housings for smartphones, base stations, and communication devices.

• Medical Devices: Found in diagnostic equipment, pumps, and surgical tools where biocompatibility, precision, and reliability are non-negotiable.

• Aerospace & Defense: Employed in avionics, navigation systems, and other critical components that demand lightweight, high-strength, and failure-proof seals in extreme environments.

• Industrial Machinery: Used as seals and spacers in pumps, compressors, control valves, and various mechanical assemblies to prevent fluid and gas leakage.
