The first electronic press brake for heavy-duty work
The e - volution in sheet-metal working reaches a new milestone
Since the very first CNCK servo-hydraulic press brake in 1980,
I-Brake won the Techni-Show Innovation Award (among others).

Turn-key delivery of automated bending solutions In 1988, SAFAN had already installed the first robotic press brake in Europe. Safan is now an experienced specialist in the field of automated bending cells including the standard SAFAN R-Brake. The SAFAN integral solutions for your production process go much further than stand-alone solutions. The integral automation is not restricted to the bending cell alone, this also applies to other parts of the process such as punching and spot-welding, and the entire routing of sheet material around the bending cell.
