Custom Photochemical Nickel Etching with Exceptional Detail and Consistency

Nickel Etching Overview
We specialize in high-precision nickel etching, offering custom fabrication of intricate and durable nickel parts. Our process is ideal for producing complex geometries, fine meshes, and micro-features that are difficult or impossible to achieve with traditional mechanical methods. We handle everything from prototype development to high-volume production runs.

Manufacturing Process
Our nickel etching utilizes advanced photochemical machining (PCM) technology. The process begins with cleaning and preparing the nickel material. A photoresist is then applied and exposed to UV light through a precise phototool of your design. The unexposed areas are developed away, and the exposed nickel is etched away using a controlled chemical solution. Finally, the remaining photoresist is stripped, leaving a burr-free, stress-free part with exact dimensional accuracy.

Nickel Etching Features

• High Precision & Complexity: Capable of producing extremely fine details, including micro-holes (down to 0.03mm), thin lines (down to 0.015mm), and complex 2D shapes without affecting material properties.

• Burr-Free & Stress-Free: The chemical etching process does not introduce mechanical stresses, burrs, or thermal distortion, ensuring part integrity and flatness.

• Excellent Consistency: High uniformity (±0.03mm) across the entire production batch, even for large volumes.

• Fast Turnaround: Rapid prototyping and production lead times due to digital tooling and efficient processing.

• Material Integrity: The process does not alter the inherent corrosion resistance, magnetic properties, or ductility of the nickel alloy.

FAQ
Q: What are the benefits of nickel etching over stamping or laser cutting?
A: Etching is ideal for thin materials (avoiding distortion), complex patterns (no tool wear), and delivers stress-free, burr-free parts much faster for prototypes, eliminating high hard tooling costs.

Q: Can you etch other metals besides pure nickel?
A: Yes. We specialize in various metals, including stainless steel, copper, titanium, and alloys like Inconel and Hastelloy.

Q: How do I submit a design for quotation?
A: Simply send your CAD drawing (DXF, DWG, Gerber preferred) along with material type, thickness, and quantity requirements. We will provide a DFM review and a prompt quote.

Q: What is the minimum order quantity (MOQ) for nickel etching?
A: We support low MOQ for prototyping. For standard parts, MOQ can be as low as one sheet, making it cost-effective for both R&D and production.

Q: What surface finishes can you apply after etching?
A: We offer various post-processing, including electroplating (gold, silver, tin), passivation, annealing, and forming.
