The large-tonnage servo press for flow battery stack assembly is a critical solution designed to address the key challenges in mass production. Featuring a robust closed-frame structure and an all-digital servo drive system, it delivers precise and stable pressure of several hundred tons. This enables uniform micro-level compaction and millimeter-accurate thickness control across the entire stack assembly, which consists of hundreds of bipolar plates, electrodes, and seals.
Integrated with smart pressing modes—including constant pressure, displacement, and curve following—the press provides full-process force-displacement monitoring and traceability. This ensures reliable sealing of flow channels and consistent interfacial contact resistance, ultimately improving the stack’s power density, energy efficiency, and cycle life. As a core enabler of high-performance, consistent, and scalable flow battery manufacturing, this press is essential to intelligent production.
PRODUCT DESCRIPTION
The stack assembly servo press is integrated with intelligent assembly modules, enabling seamless connection to automated production lines for automatic positioning, stacking, and pressing of the stack. Its core advantage lies in the precise closed-loop control and real-time feedback, which effectively eliminates human errors and traditional hydraulic fluctuations, elevating assembly accuracy to the micrometer level. Additionally, equipped with an expert database and adaptive process algorithms, the press can flexibly adapt to the process requirements of stacks with different specifications, significantly improving production cycle time and product yield. Thanks to its high reliability, digitalization, and intelligent features, this servo press serves not only as the cornerstone for enhancing the capacity and quality of flow batteries but also provides robust equipment support for the industry's transition toward high-efficiency, low-cost manufacturing.
