Frequently Asked Questions

We achieve 0.7mm for single-sided plates and 1.2mm for double-sided plates with flow channels. Our ultra-thin capability comes from proprietary machining processes developed over 15+ years of bipolar plate production.

Three proprietary coatings: (1) Non-shedding coating for clean environments, (2) High-purity carbon coating achieving 99.9999% purity, (3) Nano-hardening coating for wear-resistant applications. SiC coating via CVD is also available.

Yes. We accept 2D/3D drawings (STEP, IGES, DWG) and manufacture to your specifications. Our CNC capabilities handle tolerances down to ±0.01mm. We work with all graphite grades — isostatic, extruded, molded, and high-purity.

Standard products: 2-4 weeks. Custom components: 4-8 weeks depending on complexity. Rush orders available. We respond to all inquiries within 12 hours and provide production timelines with your quote.

Yes. Every shipment includes material certification (grade, density, grain size, ash content, flexural strength, thermal conductivity) and dimensional inspection report. Third-party testing available on request.

We work with isostatic graphite (Toyo Tanso IG series equivalents, SGL EK series), extruded graphite, molded graphite, and high-purity grades (5ppm ash or below). We can source or recommend the optimal grade for your application.
