Abstract: A hinge is formed having a hinge bolt and a U-shaped hinge support with a hinge base, an upper limb and a lower limb. The method includes placing the hinge support in manufacturing apparatus having a support base, a workpiece holder having a fixed clamping jaw and a movable clamping jaw, a tool die which includes a tubular die support and a press contour, and a press piston. The press piston is movable along a first axis to apply an adjustable pressing force on the hinge support. The support base includes cylindrical guide shafts to movably guide the workpiece holder along a second axis. The hinge support is placed relative the workpiece holder such that upper edges of the upper limb are brought into contact with a first recess in the fixed clamping jaw and a second recess in the movable clamping jaw.
