0.15mm etched steel sheets are ultra-thin stainless steel sheets that have been selectively etched using chemical processes to create intricate patterns, micro holes, or fine features.

Unlike traditional machining methods, chemical etching:

• Removes material without mechanical force or heat

• Maintains the original mechanical and chemical properties

• Produces clean, burr-free, and distortion-free parts

At TMN, we take 0.15mm stainless steel and transform it into highly accurate components that can meet the tightest tolerances required by modern industries.

Benefits of TMN’s 0.15mm Etched Steel Sheets

Choosing TMN Metal Parts Fabrications means gaining access to significant technical and manufacturing advantages:

1. Ultra-High Precision

• Tolerances as tight as ±0.01mm

• Clean, detailed cuts without sharp burrs

• Micro holes, slots, and intricate geometries

Our precision capabilities allow us to create parts that many traditional manufacturing methods simply cannot achieve.

2. Stress-Free Manufacturing

Unlike laser cutting, stamping, or punching, chemical etching introduces no heat-affected zones, no deformation, and no residual stresses. Your 0.15mm sheets retain perfect flatness and full material properties.

3. Freedom of Design

Photo chemical etching offers incredible flexibility in design:

• Fine meshes and perforations

• Complex patterns

• Custom logos, text, or serial numbers

• Multi-depth etching for added functionality

TMN’s team will work with you to bring your most intricate designs to life — quickly, affordably, and with flawless results.

4. Cost-Effective Production

Because photo tools (not hard tooling) are used, the setup costs are low, and design modifications are easy. TMN supports cost-effective prototyping, short production runs, and high-volume manufacturing with minimal lead times.

5. Consistent Quality at Scale

From one-off prototypes to mass production, TMN ensures every etched steel sheet meets the same high standards. Our quality control systems ensure excellent repeatability and zero-defect manufacturing.

TMN’s Etching Process for 0.15mm Steel Sheets

Here’s how TMN ensures consistent excellence:

1. Design and Photo Tooling:
   Your CAD designs are converted into high-resolution photo masks. This defines the precise areas to be etched on the 0.15mm sheet.

2. Surface Preparation:
   The stainless steel sheets are meticulously cleaned to ensure perfect adhesion of the photoresist layer.

3. Photoresist Application and Exposure:
   A light-sensitive resist is applied to the sheet. UV light exposes the resist through the photo mask, creating the pattern.

4. Development and Etching:
   The unexposed resist is removed, exposing the metal beneath. Controlled chemical solutions then etch away the unprotected metal, creating the desired pattern.

5. Resist Removal and Finishing:
   Once etching is complete, the remaining photoresist is stripped away, leaving clean, ready-to-use etched sheets.

6. Quality Inspection:
   Every etched sheet undergoes strict dimensional and visual inspection to meet TMN’s high-quality standards.
