OEM/ODM Chemical Nickel Etching Custom Services with High Precision 

 Nickel Etching Overview

Xinhaisen specializes in high-precision nickel etching, delivering exceptional accuracy and consistency for complex components. Our advanced etching technology ensures fine details, tight tolerances, and burr-free results, making us a trusted partner for industries requiring critical metal parts.

Manufacturing Process

Our nickel etching follows a state-of-the-art photochemical etching (PCE) process:

• Material Selection & Preparation: Sourcing high-quality nickel or nickel alloy sheets (e.g., Nickel 200/201, Inconel, Monel). The sheet is thoroughly cleaned.

• Photoresist Lamination: A uniform layer of UV-sensitive photoresist is applied to both sides.

• Exposure: The sheet is exposed to UV light through a phototool (film mask) containing the precise part design.

• Development: The unexposed resist is dissolved, revealing the nickel surface in the areas to be etched.

• Chemical Etching: The sheet is sprayed with a specialized etchant, which precisely removes exposed metal to form the desired features.

• Resist Stripping & Cleaning: The remaining photoresist is removed, and parts are thoroughly cleaned.

• Finishing & QC: Parts may receive additional finishing (e.g., plating, passivation) and undergo rigorous dimensional and visual inspection.

Nickel Etching Features

• Exceptional Precision: Achieve micro-features such as holes as small as 0.03mm and line widths down to 0.015mm.

• Burr-Free & Stress-Free: The chemical process produces clean, smooth edges with no mechanical burrs or internal stresses that can affect performance.

• Material Integrity: Maintains the inherent properties of nickel—corrosion resistance, high-temperature strength, and magnetic permeability.

• Complex Geometries: Easily produce intricate designs, fine meshes, and complex forms that are difficult or costly with stamping or laser cutting.

• Fast Turnaround & Low Tooling Cost: Digital phototools allow for rapid design changes and quick production start-up without expensive hard tooling.

FAQ

Q1: What are the main benefits of etching nickel vs. other methods like stamping?
Etching is ideal for thin, delicate nickel parts, produces no burrs, introduces no stress, and allows for more complex, fine-featured designs at a lower cost for prototypes and medium volumes.

Q2: Can you etch high-temperature nickel alloys like Inconel?
Yes. We have specialized processes for etching challenging alloys such as Inconel and Monel, commonly used in extreme environments.

Q3: How do you prevent corrosion or oxidation on nickel parts after etching?
We offer post-etch treatments like passivation to enhance the natural oxide layer or apply protective electroplating (tin, gold) as specified.

Q4: What file format do you need for production?
We accept standard design files including Gerber, DXF, DWG, and PDF. Our engineering team can assist with file preparation.

Q5: Is there a minimum order quantity (MOQ)?
No. We support projects from single-piece prototypes to mass production runs, offering unmatched flexibility.

Q6: Can you provide additional finishing like plating?
Yes. We offer various electroplating services (gold, silver, tin, nickel over nickel) to improve solderability, conductivity, or appearance.
