Description
Scratch Prevention

The key advantage of the Rolla-V Die is its incorporation of rotating rollers (mandrels) at the V-die shoulders. This design fundamentally transforms the material-tool interaction from abrasive sliding friction to smooth rolling friction during the bend. This is essential for achieving scratch-free bending on highly sensitive materials like polished stainless steel, pre-painted aluminum, and chrome-plated parts. The rollers significantly reduce surface marring and indentations, minimizing rework costs and ensuring the highest aesthetic quality directly off the press brake.

Reducing Tonnage

Another major advantage of the Rolla-V Die is the substantial reduction in the required bending tonnage. By converting sliding friction to rolling friction, the overall force needed to form the bend is lowered, reducing stress on the press brake and tooling. Furthermore, the smooth rolling action helps guide the material, leading to a more consistent and predictable degree of springback. This simplification of angle compensation means faster setup times and higher geometric accuracy in production runs, enhancing overall tooling efficiency.
