Precision in the 1/100 mm range with the EcoMaster®.


Consistently excellent leveling results, especially with thin metal sheets and parts. This is essential for optimum results during subsequent processes. Our EcoMaster® series of straighteners delivers flat sheets and parts almost entirely free of internal stresses together with extensive time savings – making your production more efficient.

• Specifically designed for thin materials: material thicknesses from 0.1 mm to 5 mm
• Highest efficiency: leveling speed of 3 to 20 m/min
• For a broad range of applications: punched and laser-cut parts, perforated plates, precious metal, aerospace, electrical- and watch-making industry

FlatMaster®: level results in a matter of seconds.


The FlatMaster® produces flat stamped, laser-cut and plasma-cut parts almost entirely free of internal stresses in a matter of seconds. With thicknesses from 0.5 to 60 mm. Even with high-strength parts and sheets with cut-outs We have been building parts levelers for more than 50 years. The FlatMaster® embodies our collective expertise. The straightener is ideal for leveling laser-cut, punched and plasma-cut parts and even AHSS materials.

• From small to large: material thicknesses from 0.5 mm to 60 mm
• Broad range of parts with maximum widths ranging from 800 mm to over 3,000 mm
• Powerful performance: servo-hydraulic leveling gap control, hydraulic overload protection system to prevent damage to the leveler and reproducible leveling results
