We realize your individual single systems for hydroforming, cutting, welding and straightening including all tools. With our stack presses, we also offer you technology for testing your fuel cell and electrolysis stacks.
Our Graebener® cutting system features a cartesian laser system and fiber laser with advanced cutting optics. From thin foils (25 µm) to massive plates for high-pressure electrolysis, it delivers precise, economical, and reliable results. High cutting speeds up to 2 m/s ensure excellent quality with minimal burrs and roughness, for both 2D and 3D cuts.
Our Graebener® welding system combines advanced fiber laser and scanner technology. Its static structure enables welding speeds up to 0.8 m/s for 100 µm stainless steel foils, with the smallest beam spots ensuring precise welding in channel structures.
With our worldwide unique Graebener® straightening technology for metallic bipolar plates, residual stresses can be significantly reduced or nearly eliminated. The contactless process preserves surface coatings and molded geometries.
Graebener® forming presses, like our hydroforming press, form bipolar plates for fuel cell and electrolysis systems. Using hydroforming, extremely thin materials from 25 µm can be formed with extremely filigrate structures in series. Compared to mechanical forming, which at first glance may seem more cost-efficient, especially for series production, hydroforming offers numerous advantages, such as repeatable precision, attention to detail and less tool wear, which pay off in the long term. Using our sandwich tool, multiple plates, such as cathode and anode sides, can be formed per stroke.
For larger and more complex projects we develop tailor-made and scalable lines for series production – from the coil to the welded bipolar plate.
We also realize customized stack presses. These support the technical testing of fuel cell and electrolysis stacks at the end of their production processes.
