From metal strip to fuel cell or electrolyzer stack
From metal strip to fuel cell or electrolyzer stack
Together with our partners VON ARDENNE (Dresden) and Zeltwanger (Tübingen), we present our highly efficient interface-tuned complete line for the production of metallic bipolar plates. With an annual production capacity of several million bipolar plates per year, it covers the current needs of the industry and has a pioneering role in the market. The machinery processes pre-stamped half-plates made of stainless steel or titanium. In the first step they are welded into bipolar plates, then leak-tested and given a PVD coating to functionalize the surface.
Full expertise from prototype production to turnkey large-scale production systems for laser welding and cutting of metallic bipolar plates
Our patented welding module for the production of metallic bipolar plates achieves very high absolute welding speeds of 1 m/s with process reliability and a large available working area. This makes
it possible to realize annual production volumes of several million units. The intelligent „butterfly weld“ welding sequence enables optimum symmetrical heat input. The static structure between the optics and clamping technology guarantees maximum contour accuracy and reproducibility.
Based on the series modules, we also offer prototype production from contour cutting of individual plates using lasers, laser welding of the bipolar plates, and the design and manufacture of the clamping device. This ensures guaranteed process reliability for you as a customer.
