Precision Aluminum Etching Service for Micro-Perf Sheets - Rapid Prototyping & Large Volume Production

Aluminum Etching Overview
Xinhaisen Technology provides high-precision chemical etching services for aluminum alloy parts, offering superior manufacturing solutions for industries requiring lightweight, corrosion-resistant metal parts. Our etching process delivers exceptional dimensional accuracy and complex geometries while maintaining the material's inherent properties.

Manufacturing Process
Our aluminum etching process follows a strict, controlled workflow:

• Material Preparation: Selection of optimal aluminum alloy (e.g., 1000, 3000, 5000, 6000 series) based on client specs. Sheet cleaning and surface preparation.

• Photoresist Lamination: Application of a uniform, light-sensitive photoresist film onto the aluminum sheet.

• Exposure & Development: The desired pattern from a digital phototool is transferred onto the resist via UV exposure. The unexposed resist is then developed away.

• Chemical Etching: The exposed aluminum areas are precisely etched away using a controlled chemical spray (e.g., alkaline etchant), forming the final part shape.

• Stripping & Cleaning: Removal of the remaining photoresist and thorough cleaning of the etched parts.

• Final Inspection & Packaging: 100% quality check for dimensions and tolerance using optical measurement tools, followed by protective packaging.

Aluminum Etching Features 

• High Precision & Complexity: Achieves fine details, sharp edges, and complex designs without tooling wear.

• No Mechanical Stress: The chemical process introduces no burrs, stresses, or heat-affected zones, preserving material properties.

• Excellent Surface Finish: Provides clean, smooth edges and surfaces.

• Rapid Prototyping & Production: No hard tooling required, enabling fast turnaround from design to sample and volume production.

• Cost-Effective for Complex Parts: Lower setup costs compared to stamping or laser cutting for intricate designs, especially in low to medium volumes.

• Material Flexibility: We etch various aluminum grades and tempers to meet specific strength, conductivity, or corrosion resistance needs.

FAQ

• Q: What file format do you need for production?
  A: We prefer AI, DWG, DXF, or Gerber files. Please ensure all critical dimensions are clearly specified.

• Q: Can you etch other metals besides aluminum?
  A: Yes. We also expertly etch stainless steel, copper, brass, titanium, and nickel alloys.

• Q: How does etching compare to laser cutting for thin aluminum?
  A: Etching produces no heat-affected zone, preserves metallurgy, and allows for more complex, multi-feature designs in a single step. It is often more economical for high-complexity parts.

• Q: Do you provide material certifications?
  A: Yes. We provide Material Certificates (Mill Certs) upon request and can source materials from certified suppliers.

• Q: What is your minimum order quantity (MOQ)?
  A: We are flexible. MOQ can be as low as 1 piece for prototyping, with no MOQ for production runs for standard projects.
