Your Graebener® Production Lines From the Individual Single System up to Scalable Production Line.

From our experience as special machine builder, we know that there is no such thing as "the one" system – because technologies and processes change with market requirements. At Graebener® Bipolar Plate Technologies, we endeavor to respond as flexible as possible to present and future requirements of our customers.

Regardless of whether you are looking at a single system tailored to your objectives, a complete production line or an extension of an existing line: In all these cases we are your flexible performance partner and realize your individual production line from coil to welded bipolar plate in close cooperation with you.

Our Services

Our individual systems: Patented technology

Our patented Graebener® systems for hydroforming, cutting and welding are ideally suited for manufacturing projects with clearly defined goals. Based on your specifications and with regard to the production parameters determined in our application laboratory, you will receive systems perfectly tailored to your needs including the necessary tools for the production of high-quality bipolar plates.

Turn our innovations into your competitive edge: e.g. with our
patented combination of sandwich tool and Graebener® hydroforming press, which allows you to simultaneously form several plates per stroke.

Growth as standard:
With scalable production lines – from coil to welded bipolar plate

Thanks to our many years of experience in mechanical engineering, we are able to develop line concepts that can grow with time. With a view to your increasing quantities or changing component geometries, we develop production lines for bipolar plates that can be scaled precisely and sustainably. The modular design of our lines guarantees a cost-efficient expansion of your production line. From the very start, our concept accompanies you safely into the future.

We determine all necessary process parameters in advance in our Graebener® application laboratory and thus realize a fast start-up of your production lines on site.

The Technologies for Optimum Performance


Graebener hydroforming press for the manufacturing of metal bipolar plates

We have developed our patented Graebener® hydroforming press especially for the economic production of metallic bipolar plates and have made it ready for series production.

With our sandwich tool, several plates can effortlessly be produced simultaneously per stroke, e.g. the cathode and anode side.

Cutting and Welding
