Core Analysis of Servo Presses for Cell Assembly

Three Core Challenges in Stack Assembly: Why Traditional Equipment Struggles to Break Through?

In the production of fuel cells and hydrogen energy storage equipment, the stack assembly process has long been plagued by three major bottlenecks that severely impact product yield and production efficiency:

● Precision Control Issues: Pressure fluctuations in traditional presses often exceed ±5% FS, leading to poor sealing and uneven current conduction during the stacking of multiple electrode plates and membrane electrode assemblies (MEAs). This results in a scrap rate exceeding 8% for finished products.

● Efficiency bottlenecks: Manual parameter adjustments require 1–2 hours per model changeover, failing to meet flexible production demands for multiple stack variants;

● Data gaps: Lack of real-time monitoring and recording for critical parameters like pressure and displacement makes assembly processes untraceable and troubleshooting inefficient.

These pain points represent the precise areas where servo presses for stack assembly are focused on achieving breakthroughs.

Three Core Values of Servo Presses: Precision, Efficiency, and Intelligence

Servo presses deliver high-precision, high-efficiency, and highly intelligent system solutions for fuel cell stack assembly through advanced technological configurations:

● Micron-level precision control effectively eliminates assembly defects

Utilizing imported servo motors and high-precision ball screws achieves pressure control accuracy of ±0.1% FS and displacement accuracy of ±0.001mm;

Real-time pressure sensor feedback triggers automatic shutdown during pressure anomalies, reducing stack scrap rates to under 0.5%.

● Flexible production efficiently adapts to diverse scenarios

Supports storage of hundreds of process parameter sets, reducing changeover time to under 10 minutes and boosting production efficiency by 40%;

Flexible single/dual-station design accommodates diverse needs from R&D prototyping to mass production (500–2000 units/day).

● Full-process data traceability for compliance and maintenance

Integrated PLC and touchscreen systems record real-time pressure-displacement curves for each stack, with exportable data or MES integration;

Remote diagnostics enable technical support teams to resolve issues online, reducing downtime by over 60%.

Servo Press Selection Guide: Four Key Dimensions and Two Major Pitfalls to Avoid

1. Recommendations for Matching Four Critical Parameters

2. Key Considerations for Avoiding Pitfalls in Equipment Selection

● Make rational choices—avoid blindly pursuing high specifications. For R&D scenarios, a 100kN model suffices to prevent resource wastage.

● Prioritize after-sales service: Select manufacturers offering 72-hour on-site support to ensure continuous, stable production line operation.

 Core Application Scenarios: Servo Presses Deliver Performance Across Multiple Sectors

● New Energy Vehicle Fuel Cells: After adoption by a leading automaker, stack qualification rates rose from 85% to 99.2%, with annual production capacity increasing by 30,000 units;

● Hydrogen Energy Storage Fuel Cells: Suitable for assembling 100kW-class energy storage fuel cell stacks, with sealing performance meeting extreme operating conditions from -40°C to 80°C;

● Specialized Fuel Cell R&D: Customized micro-press models (0.1–10kN) for aerospace and other sectors, supporting small-batch lab prototyping.

Technological Trends: Future Outlook for Fuel Cell Assembly Presses

● AI Process Optimization: Automatically adjusts pressure curves based on performance data, enabling iterative refinement of process parameters;

● Multi-Process Integration: Combines vision-based positioning (accuracy ≤0.01mm) and automated feeding to minimize manual intervention;

● Green Energy-Efficient Design: Utilizes permanent magnet synchronous servo motors, achieving over 30% energy savings compared to traditional hydraulic equipment, aligning with low-carbon manufacturing requirements.
