The 5-ton servo hydraulic press for stack assembly is a high-precision intelligent pressing machine specifically designed for stacks using metal bipolar plates, graphite bipolar plates, as well as products like PEM electrolyzers and all-vanadium flow batteries.
With a nominal pressing force of 50 kN, the machine combines servo hydraulic closed-loop control, pressure and displacement monitoring, programmable pressing recipes, stack alignment, and production data traceability. It enables manufacturers to control stack compression more consistently while reducing the risk of bipolar plate damage, uneven contact pressure, sealing defects, and assembly variation.
This equipment integrates inclined stacking technology, servo closed-loop control, and full-process data traceability. It can simultaneously perform stack assembly, compression, and in-line gas leak testing, effectively ensuring the consistency and reliability of mass production.
PRODUCT DESCRIPTION
1. High-Precision Control with Dual-Mode Interlock
●Dual Control of Pressure and Displacement: Utilizes an efficient servo hydraulic closed-loop control system, featuring high-precision pressure and displacement control to ensure a linear, stable pressing process with no overshoot.
●Multiple Operating Modes: Supports intelligent switching with pressure mode as primary and position mode as secondary. The two modes are interlocked and mutually protective in real time, allowing flexible parameter adjustment based on process requirements, providing comprehensive protection for bipolar plates (especially graphite plates) from damage.
2. Intelligent Production with Full Data Traceability
●Programmable Pressing Process: The pressing sequence is programmable, allowing users to freely set parameters such as pressure gradients, speed, and dwell time. Settings can be activated with one click, enabling quick changeovers.
●Barcode Scanner Integration: Automatically associates a stack ID, records all pressing parameters, and outputs pressure-displacement curves. Historical data is stored locally or in the cloud, enabling forward traceability from raw materials to finished products, meeting the requirements of information-based and intelligent production.
3. Precision Alignment for Improved Stack Uniformity
●Inclined Stacking Technology: Utilizes gravity to assist in the automatic alignment of plates. Coupled with center-of-gravity positioning algorithms that monitor load offset in real time, it achieves high-precision alignment, effectively eliminating cumulative errors and ensuring uniform internal contact within the stack.
●In-Line Leak Testing (Optional): Select models integrate gas leak detection functionality during the stack holding phase, allowing preliminary inspection without secondary handling, thereby improving assembly reliability and sealing performance.
4. Stable and Durable with Safe and Convenient Operation
●Hydraulic System: Employs a stable and durable servo hydraulic unit that is easy to maintain and offers high long-term operational reliability.
●Compact Structure: The top-mounted cylinder design eliminates the need for a pit. The structure is lightweight and space-saving, adapting to various workshop layouts.
●Multi-Level Safety: Equipped with light curtain safety protection. The overall design balances durability, ease of operation, and personnel safety.
Stack Types: Metal bipolar plate stacks, Graphite bipolar plate stacks
Application Areas: Stack assembly and compression for fuel cell stacks, PEM electrolyzers, all-vanadium flow battery stacks, etc.
With its high-precision control, intelligent management, and stable, reliable design, this equipment helps stack manufacturers achieve efficient, high-yield mass production.

A fuel cell stack contains multiple bipolar plates, membrane electrode assemblies (MEAs), seals, and end plates. During assembly, these components must be compressed to a controlled stack height and clamping force.
Insufficient or uneven compression can lead to:
● Poor sealing between stack layers
● Uneven contact pressure
● Increased electrical contact resistance
● Gas leakage
● Bipolar plate deformation or cracking
● Inconsistent stack performance
The Shuntian fuel cell stack assembly press uses servo-controlled pressure and displacement feedback to maintain a stable compression process and improve repeatability between individual stacks.
The 5T Stack Assembly Servo Press can operate as an independent assembly station or become part of a complete automated production system.
Shuntian provides equipment covering fuel cell stack preparation, assembly, compression, testing, and production-line automation, allowing manufacturers to develop solutions from laboratory-scale process verification to mass-production lines.
