The seminar featured keynote presentations, technical insights, live demonstrations, and in depth industry exchanges, offering a comprehensive view of the latest achievements and future directions in precision forming of metal bipolar plates.Highlights included:

• Liu Mingxing, from Metal Forming Intelligent Manufacturing (MFC), sharing insights into China’s hydrogen energy market trends and current development status.
• Du Yongxiang, Vice President of Zhizhen Co., Ltd., presenting technological breakthroughs in high power fuel cell metal bipolar plates.
• Jilu Jun, Vice President of DIJET Japan, introducing significant advancements in tooling materials and efficiency, developed in collaboration with TOWA.
• Professor Liu Yuqi, from Huazhong University of Science and Technology, showcasing simulation driven optimization of precision forming for metal bipolar plates and heat sinks, enabling efficient mass production of ultra thin sheets.
• Dr. Yang Cheng Yu, from National Kaohsiung University of Science and Technology, sharing expertise on precision forming processes for bipolar plates, integrating CAE simulation with SEYI servo presses to optimize die structures, control thinning rates in critical areas, and ensure stable forming of complex flow channels.
  

Mr. Lin Ming Yang, Director of SEYI Machinery, introduced the SDK1 Series high rigidity, high precision servo press, purpose built for plate forging and precision forming applications—making it an ideal solution for hydrogen fuel cell metal bipolar plate production. Building upon the strengths of conventional servo presses, the SDK1 series delivers comprehensive upgrades: 

• Exceptional Structural Rigidity: With rigidity up to 1/36,000 and deformation ≤ 0.03 mm, the frame’s tensile deformation is reduced by over 40% compared to conventional straight side presses. This ensures stable support for ultra thin metal forming in the 0.075–0.1 mm range.
• Ultra High Precision Control: Equipped with zero clearance slide guides, the press achieves JIS Special Grade accuracy, ensuring smooth slide motion and reliable control of critical requirements—flow channel depth ±0.02 mm and warpage ≤ 2 mm.
• Energy Efficient, High Performance: Featuring a press dedicated “high torque low speed” servo motor, supports power leveling and regenerative energy recovery, and significantly reduces energy consumption—ideal for long hour continuous mass production.
  
  

Live Demonstration of Metallic Bipolar Plate Stamping

Attendees were invited to witness a live demonstration using the SDK1 160 servo press, processing 0.1 mm stainless steel metal bipolar plates. The demonstration showcased the press’s outstanding performance in micro channel stamping, forming depth control, and ultra thin sheet processing, allowing participants to experience the advantages of SEYI servo press technology firsthand.

Partnering with Industry to Accelerate Hydrogen Manufacturing Upgrades

In his closing remarks, Mr. Steven Lee, President of SEYI Machinery, emphasized that global growth in the hydrogen fuel cell vehicle market is driving strong and sustained demand for metal bipolar plates—a demand conventional manufacturing approaches can no longer satisfy.Thanks to their energy efficiency, precision, and operational flexibility, SEYI servo presses offer customers a powerful tool to enhance productivity and competitiveness.

Looking ahead, SEYI will continue to deepen its technical expertise and strategic investment in hydrogen energy equipment and precision stamping technologies, supporting the industry’s transition toward large scale, cost efficient manufacturing.
