Plastic forming method for bending metal plates, pipes and profiles into a certain angle, curvature and shape. Bending is one of the main processes widely used in stamping parts production.
The bending of metal materials is essentially an elastoplastic deformation process. After unloading, the workpiece will produce elastic recovery in the direction of deformation, called rebound. Springback affects the accuracy of the workpiece and is a technical key that must be considered in the bending process.
