From our experience as custom machine builder, we know that there is no such thing as "the one" machine – 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 machine tailored to your objectives, a complete production line or an extension of an existing line, and regardless of whether you want to manufacture fuel cell or electrolysis components: In all these cases we are your flexible performance partner and realize your individual solution in close cooperation with you.
Our patented Graebener® machines for hydroforming, cutting, welding and straightening are ideally suited for manufacturing projects with clearly defined goals. Based on your specifications and with regard to the production parameters determined in our production laboratory, you will receive machines 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.
In addition, we support you with our stack press in the technical testing of your fuel cell and electrolyzer stacks.
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® production laboratory and thus realize a fast start-up of your production lines on site.
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.
With laser fusion cutting, we use a process that achieves a very high level of accuracy and quality.
And this is achieved without significant maintenance costs or tolerance problems due to tool wear.
This ensures fitting accuracy even for complex structures.
Not only do we form your bipolar plate for fuel cells and electrolyzers precisely. As an experienced technology and equipment partner, we are also at your side for the subsequent welding process.
As with cutting, we also use the advantages of laser technology here. Benefit from our many years of practical experience.
Our specially developed and worldwide unique straightening machine offers for the first time the possibility to produce flat bipolar plates.
A necessary requirement for both economical stack production as well as high performance and durability of the stacks.
With our technology we support the technical testing of your fuel cell or electrolysis stacks.
