Curved shapes: conventional arc, U, S, circular, parabola, and asymmetrical circular arcs with straight lines.

Bending quality: cavity profiles, cross section of complex profiles can be formed in one time. The surface treated materials such as spray, electrophoresis, electroplating, polishing and wire drawing can be directly drawn and bent without damage to the material surface when the elongation is small, because the tensile bending is cold processing, and the overall strength of the material can be improved after bending.

Materials such as spraying, electrophoretic, electroplating, polishing, drawing, etc. can be flexed directly, without damage to the surface of the material.

The profile of the cavity and complex section can be formed at one time. When the relative bending radius is allowed, the inner wall will not wrinkle and the cross section will not be distorted.

The tensile bending can effectively eliminate the residual stress inside the material, and the stability of the product size is good.

The mechanical properties of the material can be improved because of the cold hardening of metal materials.

The essence of strip shape defects is due to the different internal stresses in the width direction of the strip, resulting in a very small length difference between the longitudinal fibers along the width side and the adjacent longitudinal fibers. Strip shape to be flat, only by stress exceeding the yield strength of the strip length direction, then the length of fiber and plastic deformation, the stress relaxation after the extension of variable length fiber is still retained, which tends to be the same strip internal longitudinal fiber length and internal stress, and the same direction, to achieve purpose of leveling.
