Photochemical Machined Gaskets & Metal Spacers with High Volume Production & Fast Delivery

Metal Shims Overview

Our metal gaskets are precision-etched parts designed for superior sealing and performance in demanding applications. Manufactured using advanced chemical etching technology, they ensure high accuracy, consistency, and reliability across various industries.

Manufacturing Process
We specialize in precision chemical etching, enabling us to produce complex gasket designs without burrs, stress, or material deformation. This process ensures tight tolerances and clean edges for every part.

What Is Chemical Etching?

Chemical etching is a precision manufacturing process that uses controlled chemical reactions to selectively remove material from metal sheets. Unlike traditional stamping or laser cutting, etching does not introduce mechanical stress or burrs, allowing for extremely fine features, tight tolerances, and consistent quality — even in high-volume or complex designs.

Metal Shims Features

• Extreme Precision & Consistency: Achieve tight tolerances down to ±0.01mm with uniform performance across high-volume production runs.

• Burr-Free & Stress-Free Components: Chemical etching ensures clean, smooth edges without mechanical deformation or thermal stress, maintaining material integrity.

• Wide Material & Thickness Flexibility: Compatible with stainless steel, copper, aluminum, nickel, titanium, and more, supporting thicknesses from 0.02mm to 1.5mm.

• Complex Design Capability: Easily produce intricate geometries, fine holes (as small as 0.03mm), and ultra-narrow lines (down to 0.015mm) without costly tooling.

• Rapid Prototyping & Mass Production: Quick turnaround from design to delivery, ideal for both sample requests and large-scale orders.

FAQ

• Q: What materials can you use for metal shims?
  A: We work with stainless steel (304, 316, 301, etc.), copper, brass, nickel, titanium, and other alloys. Custom materials can be sourced upon request.
• Q: What is the minimum thickness available?
  A: Our etching process supports metal thicknesses as low as 0.02 mm, making it ideal for ultra-thin shim applications.
• Q: Can you produce complex shapes with tight tolerances?
  A: Yes. Chemical etching allows for intricate geometries with tolerances as tight as ±0.01 mm, depending on material and thickness.
• Q: Do you offer prototyping services?
  A: Absolutely. We provide fast prototype services with low tooling costs and can scale to high-volume production seamlessly.
• Q: How do etched shims compare to stamped or laser-cut shims?
  A: Etched shims are burr-free, stress-free, and maintain flatness. They are ideal for applications requiring precision, cleanliness, and consistent mechanical properties.
