Etched Micro Parts

At TMN Metal Parts Fabrications, precision is not just a goal — it's our promise. Our specialized etched micro parts are engineered with meticulous care to meet the highest standards of accuracy, complexity, and quality. Through advanced chemical etching technology, TMN manufactures ultra-fine components that play a critical role across a wide range of industries, from electronics to aerospace.

In today's fast-evolving technological landscape, the demand for miniaturized components with complex geometries is growing faster than ever. TMN is proud to stand at the forefront of this evolution, providing micro parts that deliver outstanding performance without compromising material strength or design integrity.

What Are Etched Micro Parts?

Etched micro parts are tiny, intricate metal components created through a controlled chemical process called photo chemical etching or chemical milling. Unlike traditional machining methods, chemical etching allows for the production of highly detailed patterns and complex shapes without inducing mechanical stress or altering the material’s properties.

This method is ideal for producing thin, lightweight, and highly accurate parts that would be impossible or too costly to fabricate using conventional cutting or stamping techniques.

At TMN, our photo chemical etching process ensures:

• High repeatability and precision

• Minimal material distortion

• Smooth, burr-free edges

• Complex designs with ultra-fine features

Why Choose TMN for Etched Micro Parts?

At TMN Metal Parts Fabrications, we offer more than just etching services — we deliver end-to-end solutions tailored to your project's unique requirements. Here’s why leading companies trust TMN:

1. Exceptional Precision and Detail

Our advanced etching systems can achieve tolerances as tight as ±0.01 mm. Whether your design calls for micro-holes, intricate mesh patterns, or ultra-thin structures, TMN ensures flawless execution every time.

2. Wide Range of Materials

We etch on a diverse range of metals, including:

• Stainless Steel

• Copper

• Brass

• Nickel

• Aluminum

• Specialty alloys (e.g., Inconel, Kovar)

Our team provides expert guidance to help you select the right material for your application, ensuring optimal performance and durability.

3. Stress-Free, Burr-Free Fabrication

Unlike laser cutting or stamping, chemical etching does not introduce heat, pressure, or mechanical stress to the metal. This means the material’s original properties — like conductivity, magnetic permeability, or mechanical strength — remain intact.

The result? Perfectly flat, smooth parts with no burrs, deformation, or heat-affected zones.

4. Cost-Effective for Prototypes and Mass Production

Whether you need a few prototypes or high-volume production runs, TMN offers scalable manufacturing solutions. Our photo tool-based process means rapid design changes are simple and affordable — perfect for industries where innovation never stops.

5. Fast Turnaround Times

TMN is committed to delivering high-quality etched micro parts on time, every time. Our streamlined workflow and in-house capabilities enable us to meet even the most demanding production schedules.

TMN's Etching Process: A Step-by-Step Overview

To guarantee consistent quality and high precision, TMN follows a meticulous etching process:

1. Design and Tooling:
   Your CAD design is transferred onto a high-resolution photoresist film.

2. Metal Preparation:
   The metal sheet is cleaned and prepared to ensure perfect adhesion of the photoresist.

3. Photoresist Application:
   A light-sensitive coating is applied to the metal, then exposed to UV light through the photo tool.

4. Development:
   The unexposed areas of the photoresist are washed away, revealing the metal to be etched.

5. Etching:
   The exposed metal areas are dissolved using a carefully controlled chemical solution.

6. Resist Removal and Finishing:
   The remaining photoresist is stripped away, and the etched parts are cleaned, inspected, and packaged.

At every step, TMN maintains strict quality control to ensure that every etched micro part meets your specifications precisely.

TMN's Commitment to Quality

Quality isn't just a department at TMN — it's built into everything we do. We are ISO-certified and adhere to the strictest international standards for manufacturing and inspection.

Every batch of etched micro parts undergoes comprehensive testing, including:
