HGTECH Showcased at Hydrogen Technology Expo Europe
2025-10-23520
Hamburg, Germany — October 21–23, 2025 — HGTECH presented a comprehensive range of laser intelligent manufacturing solutions for the hydrogen energy industry at the Hydrogen Technology Expo Europe in Hamburg, attracting wide attention from global industry professionals.
As the global energy transition accelerates, the hydrogen industry is experiencing rapid growth. Grasping this historic opportunity, HGTECH has developed comprehensive “Laser + Intelligent Manufacturing” solutions that cover the entire hydrogen production chain — empowering the industry to achieve higher efficiency, precision, and sustainability.
At this year’s exhibition, HGTECH focused on intelligent manufacturing solutions for alkaline electrolyzers and metal bipolar plates, drawing numerous visitors to its booth to discuss future innovations in hydrogen manufacturing.
Intelligent Manufacturing Solutions for Alkaline Electrolyzers
HGTECH’s solution for alkaline electrolyzers covers automatic assembly and laser welding of electrode frames and plates, as well as automatic weld grinding, 3D weld-seam inspection, airtightness testing, stress-relief treatment, and flatness measurement — enabling full-process automation and quality assurance.
1.Modular Laser Welding System for Electrolyzer Plates
Supports flexible plate sizes ranging from 0.5 m to 2.6 m;
Equipped with an innovative magnetic-clamping fixture for smooth and stable positioning;
Compatible with both dimpled and flat plate structures, with changeover time of less than 2 hours.
02.Dual-Sided Intelligent Robotic Laser-Welding System
Ensures post-welding deformation ≤ 1 mm for 1000 Nm³/h electrolyzers, eliminating the need for rolling or flattening;
Utilizes beam-shaping technology for smooth, full weld seams without undercut;
China’s first system with a real-time weld-tracking function that guides robotic welding in the XYZ axes, guaranteeing consistent weld quality.
03.Intelligent Factory for Alkaline Electrolyzers
Enables real-time weld-quality monitoring and automatic fault alerts;
Achieves 100 % automation, 100 % self-inspection, 100 % digital traceability, and 100 % information sharing.
Intelligent Manufacturing Solutions for Metal Bipolar Plates
1. Metal Bipolar Plate Automatic Welding Production Line
This fully automated production line is designed for mass production of metal bipolar plates, integrating automatic loading/unloading, welding, inspection, code assignment, and real-time data upload for remote monitoring and traceability.
Industry’s first fully automated production line with a first-pass yield exceeding 98 %；
Dual-line configuration for simultaneous loading, welding, visual inspection, airtightness testing, coding, and sorting;
Incorporates a flying-weld system and integrated fixture, precisely controlling weld penetration depth within ± 0.01 mm;
Each product carries a unique digital ID for complete quality traceability；
Automated sorting system integrated with MES management to prevent material mix-ups.
2.Metal Bipolar Plates Smart Factory
HGTECH offers a one-stop solution covering the full manufacturing process — from raw-material preparation, stamping, cleaning, welding, coating, adhesive application, inspection, to finished-product shipment.
Supports annual production capacities of 0.5–5 million plates;
Compatible with stainless steel and titanium plates, both pre-coated and uncoated process routes;
Features a smart workshop management system for real-time production visibility.
Toward a Smarter, Greener Hydrogen Future
Looking ahead, HGTECH will continue to align with global carbon-neutrality goals, deepening the integration of laser technology and hydrogen manufacturing. Together with its international partners, the company is committed to pioneering new paths in hydrogen intelligent manufacturing and driving high-quality, sustainable growth of the global hydrogen industry.
