Hydroforming Presses for external and internal high-pressure forming – smart forming of components with complex geometries for lightweight design and fuel cell technology
As one of the few hydroforming pioneers we have been developing our hydroforming lines since the mid 1980ies. Based on this long-term experience we realize your customized solution from a wide range of various press designs. Each machine is matched and tailored for the respective type of application.
Alternatively, we can modernize your existing system and future-proof it for the decades ahead.
Customized production lines for the series production of metal bipolar plates – for fuel cells and electrolyzers
Based on our core competences forming, cutting, welding and straightening we have been involved in research and development of production processes for metal bipolar plates for more than 20 years. From engineering through prototyping and small series production up to production lines – we implement solutions tailored to individual demands.
Our stack presses complement the Graebener® portfolio and support you in the technical testing of your fuel cell and electrolysis stacks.
2-Side Crimping Presses – for wall thicknesses above 85 mm (incl. Clad)
Our Graebener® crimping press for a two-side crimping in a step-by-step process provides you with the perfect crimped edge without any plate waviness, material roll out or squashing. Since there is no plate waviness, a zero gap with no edge offset can be achieved for a perfect weld seam preparation. In addition to this, our press can be used irrespective of the material, especially for the production of Clad pipes. Get unrivaled results for wall thicknesses above 85 mm.
Pipe Bending Presses – for pipes with a wide range of dimensions
Highly flexible, reliable and economic: Graebener® pipe bending presses provide you with the decisive competitive edge in the production of LSAW pipe between 16 and 64" resp. half-shells up to 100". Benefit from our experience and the special characteristics of the Graebener® technology – especially when it comes to increased wall thickness up to 75 mm and special requirements. Be different than the standard.
