As technology and system partner we lead you to the limits of feasibility. 

Based on our core competences forming, cutting and welding we have been among the leading developers and manufacturers of production lines for the cost-effective production of metal microstructure plates for more than 15 years. From engineering and prototyping services through small series production up to the customized production lines we support and accompany you on the path to a new and pioneering dimension of the forming technology.

As special machine manufacturer and hydroforming expert we have been developing the hydroforming process since the mid-80ies. Based on this pool of experience we realize your customized solution tailored to your individual market demands.

Today, we are one of the pioneering companies in the fuel cell sector when it comes to the production of separator plates. Based on our long-term development in the business area "New Technologies" we provide the know-how of the entire value-added chain for the production of highly precise and powerful separator plates for LT-PEM, HT-PEM, DMFC and SOFC fuel cells as well as for the LT-PEM electrolysis. Numerous application tests, including a Range Extender project for the Fiat 500, give proof of that.

Microstructures have also become increasingly interesting for other fields of application: Above all for manufacturers of heat exchangers and developers of redox flow batteries.

It is our commitment to make you better and provide you with the decisive competitive edge. So a Graebener® solution is no standard solution. A Graebener® solution is your individual solution tailored and customized to your requirements and needs. Graebener® is your chance to stand out from the standard. 

Machine the difference.
