Ultra-thin etched steel sheets are precision-engineered metal sheets, typically ranging from 0.03 mm to 0.5 mm in thickness, that undergo chemical or laser etching to produce detailed patterns, cutouts, or textures. These sheets are ideal for micro-components and applications that require:

• Lightweight yet strong materials

• Micro-scale patterns or holes

• Tight tolerances and high repeatability

• Non-burred, clean edges

Unlike traditional machining or punching, the etching process removes metal without stress, distortion, or deformation — making it perfect for ultra-thin steel materials.

Our technical team will help you choose the best material for your specific application and thickness requirements.

Etching Capabilities

At TMN Metal Parts Fabrications, we offer both chemical etching and laser etching techniques:

Chemical Etching (Photochemical Machining)

This technique involves applying a photoresist to the sheet, exposing the pattern with UV light, and then immersing it in a chemical etchant. Key benefits include:

• Micron-level precision

• Burr-free, distortion-free edges

• Complex geometries without tooling wear

• Ideal for thin-gauge materials (0.03 mm–0.5 mm)

Laser Etching / Engraving

Laser systems allow us to add logos, labels, part numbers, and traceability features onto thin metal surfaces. Laser marking is permanent and clean, with minimal thermal impact on ultra-thin materials.

Customization Options

Every project at TMN is unique. We offer a wide range of customization options for your ultra-thin etched steel sheet:

• Sheet Thickness: From 0.03 mm to 0.5 mm

• Sheet Size: Standard or custom dimensions based on your application

• Pattern Design: Custom cutouts, grids, perforations, logos, or complex geometries

• Surface Finish: Matte, brushed, polished, or passivated

• Color Fill: For visual branding or identification

• Serialization: Marking for batch tracking or part ID

Simply send us your technical drawings or discuss your design with our team — we’ll bring it to life with unmatched precision.

Advantages of Ultra-Thin Etched Steel Sheets by TMN

1. High Precision, Minimal Tolerance

Etching allows us to achieve extremely tight tolerances (±0.01 mm or better), even on the thinnest sheets.

2. No Mechanical Stress or Warping

Chemical etching is a non-contact process that preserves the mechanical properties of thin steel without causing distortion.

3. Scalability from Prototype to Production

Whether you need a one-off prototype or high-volume runs, our etching process is fast, cost-effective, and repeatable.

4. Environmentally Responsible

Our processes generate minimal waste, and all metals are recycled in compliance with environmental standards.
