New Generation of Controllers for Hydroforming Presses

Highly Complex Processes
Easily Controlled

We support our customers in their efforts to be the best in their field and always one step ahead of their competitors. Rexroth’s progressive automation solution enables the German manufacturer Gräbener Maschinentechnik to easily and safely manage complex hydroforming processes. Gräbener benefits from additional productivity, profitability and efficiency in the manufacturing of prototypes and offers automotive customers a considerable technological advantage.

 

Today, hydroforming is one of the key technologies in the metal processing industries. An oil/water emulsion is used to reshape tubes and profiles under high pressure, for instance in the manufacturing of very light and robust automobile body parts.

One of the pioneers in this technology is Gräbener Maschinentechnik GmbH & Co. KG, a manufacturer of hydroforming presses and operator of the world’s largest prototyping centre. Because of its industry experience, Rexroth was the partner of choice for Gräbener Maschinentechnik in the development of a new generation of control systems.

Customized solution

At the company headquarters in Lohr am Main, Germany, Rexroth designed an entirely new control and automation system for all hydraulic presses, based

on the motion logic system IndraMotion MLC. Pre-installed controllers accelerate the highly complex hydroforming processes and thus increase the productivity and profitability of Gräbener’s machines. The engineering framework IndraWorks and a software interface conforming to PLCopen standards facilitate easy engineering and the flexible adaptation of processes.

New control system generates added value

The intelligent control system provided by Rexroth improves the energy efficiency of the hydroforming presses. Condition monitoring helps to reduce the wear on components. Customers of Gräbener Maschinentechnik as well as Gräbener’s prototyping centre benefit from added value: higher productivity and reduced life cycle costs.
