Precision Etched Aluminum Bipolar Plates for Fuel Cells with Superior Conductivity & Lightweight

Aluminum Etching Overview

Xinhaisen specializes in precision chemical etching of aluminum and aluminum alloys, delivering burr-free, stress-free components with exceptional accuracy. Our proprietary etching process enables complex geometries in aluminum that are difficult or impossible to achieve with mechanical machining, making it ideal for lightweight, high-strength applications across industries.

Aluminum Etching Key Advantages

• Complex, Burr-Free Geometry: Creates intricate, multi-level flow fields with absolute zero burrs, preventing damage to delicate Membrane Electrode Assemblies (MEAs).

• Superior Precision & Uniformity: Achieves highly consistent channel dimensions and depths across the entire plate surface, ensuring predictable and reliable performance.

• No Stress or Hardness Change: The etching process is non-contact and thermal-free, preserving the aluminum's original metallurgical properties and preventing part deformation.

• Rapid Prototyping & Lead Time: Go from design to functional prototype in days, not weeks, accelerating your R&D cycle.

• Cost-Effective for Complex Designs: No hard tooling required, making it ideal for custom, low to medium-volume production runs without significant upfront investment.
