What is Etching?
Etching is a precise manufacturing process that uses chemical solutions to selectively remove material from metal sheets, creating intricate designs, patterns, or micro-features without affecting the material's inherent properties. It is ideal for producing burr-free, stress-free, and high-precision thin metal parts.
Bipolar Plate Overview
Our etched bipolar plates are key components for fuel cells and flow batteries, designed to facilitate efficient gas/liquid distribution, electrical conductivity, and thermal management. Manufactured using advanced chemical etching technology, these plates feature ultra-fine, complex flow field patterns with exceptional accuracy and consistency, ensuring optimal performance and durability in demanding energy applications.
Bipolar Plate Features
High Precision: Achieves intricate flow field designs with channel/ridge accuracy up to ±0.03mm.
Burr-free & Stress-free: No mechanical deformation or thermal stress, ensuring structural integrity.
Complex Design Flexibility: Easily accommodates custom patterns, micro-channels, and multi-scale features.
Material Versatility: Suitable for various conductive metals including stainless steel, titanium, and copper alloys.
Rapid Prototyping & Production: Quick turnaround for both samples and large-volume orders.
Excellent Consistency: Uniform etching depth and feature geometry across large batches.
