Springback is an attempt at material will recovery after bending. Due to all kinds of materials, there is a limitation of Modulus of elasticity.
Control the rebound will rely on the radius of the bend and the thickness of the material. The uniformity of the thickness and the increase of the radius of curvature. Cause to rebound increase. To obtain the desired shape. The workpiece may be bent more than required. Example below shows. The bending over the desired shape
