Mark-free bending with winged surfaces
The bending die with winged surfaces allows mark-free bending because the sheet is not drawn through the die. The pivoting wing-surfaces can be used to bend short legs without deformation that may occur at penetrations near the edge line. Wing bending dies are available for sheet thicknesses of 0.5 to 6.0 mm and tool lengths of 50, 100 and 200 mm.
