Servo-Hydraulic Stack Assembly Pressing Machine D-20T

The Servo-Hydraulic Stack Assembly Machine is a precision stack compression and assembly system designed for electrolyzer and fuel cell manufacturing, R&D, and pilot-scale production.

With 20 tons of maximum pressing force, ±0.01 mm displacement repeatability, programmable multi-stage pressing, real-time force/displacement monitoring, and an integrated 2-channel leak testing system, this D-20T machine provides the precise and repeatable compression control required for advanced electrochemical stack assembly.

Whether you are developing a new electrolyzer stack or scaling up production, the D-20T provides a flexible platform for controlled, traceable, and repeatable stack assembly with one year warranty.

Main features

✓ 20-Ton High-Precision Pressing
Up to 20 Tf of pressing force with 0.01 T pressure-setting resolution, providing controlled compression for stack assembly.

✓ ±0.01 mm Displacement Repeatability
High-precision displacement control helps achieve consistent stack compression and repeatable assembly results.

✓ Programmable Pressing Profiles
Set and control multi-stage pressure, displacement, speed, detection pressure, pressing position, and pressure-holding time for different stack designs and assembly processes.

✓ Real-Time Force & Displacement Monitoring
The industrial touchscreen HMI displays pressing force, displacement, speed, pressure-holding time, and real-time pressure curves.

✓ Built-In Process Data Management
Store 200,000+ groups of pressing-process data, including product number, operator, date, pressing force, position, and result. Data can be exported in Excel format through USB.

✓ Integrated Leak Testing
The integrated leak-testing system provides 2 independently controlled channels, differential-pressure measurement, 0–5 MPa test pressure, dynamic leakage curves, and automatic Pass/Fail evaluation.

✓ Automatic & Manual Operation
Run production automatically or control individual process steps manually for development, troubleshooting, and process optimization.

✓ Flexible Tooling Interface
Screw-hole or T-slot mounting allows customized stack assembly fixtures and tooling to be installed.

✓ Comprehensive Safety Protection
Four-sided safety light curtains, mechanical and electrical limits, emergency stops, emergency braking, overload protection, and audible/visual alarms help provide a safe operating environment.
