Photo Chemical Etched Metal Gaskets & Shims with Burr-free Edges and Fast Lead Time

Product Overview

Xinhaisen Technology's Metal Shims are ultra-thin, precision components manufactured to exacting standards for spacing, adjusting, aligning, and distributing loads within assemblies. Utilizing advanced chemical etching technology, we produce burr-free, stress-free shims from a wide variety of metals. These components are essential for achieving high-precision tolerances in industries ranging from consumer electronics and acoustics to automotive and medical devices. Our expertise allows us to manufacture metal shims with exceptional flatness and intricate geometries that are impossible to achieve with traditional stamping or mechanical cutting methods.

What is Etching?

Etching, also known as chemical etching or photo-chemical machining, is a precision manufacturing process used to create complex metal components. The process begins with cleaning the metal and laminating it with a light-sensitive photoresist. A high-resolution image of the part is then exposed onto the photoresist using UV light. The unexposed areas of the resist are washed away, leaving a protective mask on the metal. The exposed metal is then chemically dissolved in a controlled environment, creating the precise feature. Finally, the remaining protective mask is stripped away, revealing a finished, burr-free shim. This method allows for the creation of intricate designs without altering the physical or magnetic properties of the source material.

Product Features

• Micro-Precision Tolerances: Achieve extremely tight tolerances with our advanced etching lines. We produce features with high uniformity, ensuring a perfect fit for your most sensitive applications.

• Burr-Free & Stress-Free: Unlike stamping, the chemical etching process produces absolutely no burrs and induces no mechanical stress. This preserves the original flatness and material properties of the metal, guaranteeing consistent performance and preventing damage to mating surfaces.

• Ultra-Thin Capabilities: We specialize in manufacturing shims from very thin materials, ranging from ultra-thin foils to thicker plates. This allows for precise adjustments in tight spaces where traditional shims cannot be used.

• Complex Geometries: The etching process is not limited by tooling constraints. We can produce virtually any two-dimensional shape, including those with intricate internal cutouts, micro-holes, and fine lines, offering design freedom that mechanical processes cannot match.

• Material Versatility: We are proficient in etching a wide array of metals, including various grades of stainless steel, copper alloys such as brass and beryllium copper, aluminum, titanium, and high-carbon steel.

• Rapid Prototyping & Scalability: With low tooling costs, we can quickly produce samples for design validation within a short timeframe. Once approved, our production capabilities allow us to seamlessly scale to meet large-volume orders with speed and efficiency.

Frequently Asked Questions

• What is the maximum thickness you can etch for a metal shim?
  Based on our company's capabilities, we can professionally etch metal shims across a wide range of thicknesses, from ultra-thin foils up to thicker plates.
• What is the tightest tolerance you can hold on a metal shim?
  Our standard precision uniformity is held to very tight tolerances. For specific applications and material types, we can often achieve even tighter specifications to meet your exact requirements.
• Can you manufacture shims with very small holes?
  Yes. Our advanced etching process allows us to create micro-holes and fine lines with extremely small dimensions, making us well-suited for components requiring high-density, precision features.
• Are your metal shims flat and free of burrs?
  Absolutely. Because etching is a chemical process, it does not create the mechanical stresses or shear forces that cause warping and burrs. This guarantees a flat, burr-free shim that will not damage your assembly during installation or use.
• What file formats do you accept for a quote?
  We accept standard two-dimensional design files such as DXF and DWG. Our engineers can work directly from your drawings to create the perfect part for your application.
• How quickly can you provide samples?
  We pride ourselves on our rapid turnaround. We can typically produce samples in a very short time frame, allowing you to quickly validate your design. Please contact us directly with your specific requirements to discuss your project timeline.
