Graebener^® Hydroforming.
The Web Special

Forming with the power of water: We support and accompany you from the first component idea through the protoyping up to your individual Graebener^® press. Holistic, practical, customized: Graebener^® makes the difference.

Your Idea

Optimum and individual solutions are benchmarks of our work. Therefore, your idea always is the starting point of our collaboration. Based on your initial considerations, component designs or existing products we support and accompany you along the entire process chain. Our hydroforming experts conduct quick initial analyses and give recommendations on how to achieve the optimum results.

Simulation Phase

Based on our decades of experience, initial feasibility studies provide us with insight into the special requirements of your components quite quickly. Due to the different characteristics such as yield points, stretching capacity and strength your component is examined on an individual basis. We evaluate the material as well as the wall thickness or the stretching and forming limits. For the subsequent simulation, only the most modern, linear and non-linear calculation programs are used.

The Optimum Tool

Based on the simulation results we calculate all relevant parameters for the optimum design of your tool. By means of FEM calculations we engineer the initial design und dynamic conditions and optimize this design up to the desired result. All prototyping and series tools are tested prior to delivery in the Graebener^® Prototyping Center together with you.

Prototyping and Small Series Production

Think big – start small: Benefit from the Graebener^® Prototyping Center. In our workshops we have available our own press capacities with closing forces of up to 10,000 tons and table surfaces up to a size of 6 x 2.20 meters. This is unique worldwide in the field of hydroforming. As technology and equipment partner we support you drawing back on decades know-how along the entire value-added chain.

FEM for Your Benefit

For your benefit, a major focus when designing the Graebener^® hydroforming presses is the durability of the machines. For this purpose, we conduct detailed FEM calculations for each machine with the emphasis on press durability. This way, we provide you with the decisive technological edge in the long run.

Your Individual Graebener^® Press

As individual as your requirements: We design hydraulic presses ideally customized for your requirements. 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 Graebener^® press from a wide range of various press designs: 4-column presses, C-frame presses and frame presses.

To your solutions

Retrofit Solutions

New power for old technology: benefit from the economic advantages of a retrofit. We update your existing machines or entire production lines according to the latest technological standards. Based on decades of experiences, a holistic machine approach and your individual market requirements we offer extensive and competent advice and realize your personal retrofit solution from one source: fast, reliable, economic and far beyond common standard. We provide you with the decisive competitive edge.
