Graebener Maschinentechnik GmbH & Co. KG

Graebener Maschinentechnik GmbH & Co. KG is a German machinery and plant engineering company based in Netphen, Germany. It is known in particular for its Graebener® Bipolar Plate Technologies business, which supplies equipment and complete production lines for manufacturing single and bipolar plates — the core components of fuel cells and electrolysers. The company positions itself as a partner that accompanies customers from initial engineering through to the final production facility, covering forming, cutting, welding and straightening processes as well as the tooling required for them. Graebener's offering spans individual machines and scalable lines for series production, from coil handling through to the finished single or bipolar plate. Beyond the machines themselves, the company provides engineering services and operates a production laboratory, and it also offers a stack press to support customers in stack assembly. This combination of process know-how, tooling and line integration places Graebener in the hydrogen and fuel-cell supply chain rather than in general-purpose machine tools alone. The company is active in industry associations and publicly funded research. Its staff have held positions in the VDMA Fuel Cell Working Group, and Graebener participates as a sub-supplier in the publicly funded BeHyPSy research project on air-cooled fuel cell technology. It also engages in technical forums such as the Fraunhofer IWU specialist forum for tube, profile and hydroforming technologies. Graebener is a privately held German company; its registered office is in Netphen, in the Siegen-Wittgenstein district of North Rhine-Westphalia.
