Abstract

A method for producing a formed component is disclosed. The method includes: preforming a workpiece to a preformed component having a base region, a wall region, and optionally a flange region, wherein a material quantity adaptation is set in the preformed component; and calibrating the preformed component to a finally formed component, at least in regions, having a base region, a wall region, and optionally a flange region, wherein compressing of the preformed component is performed at least in regions during the calibrating. The method provides a formed component wherein the dimensional accuracy is improved and, in particular, any spreading of the walls of U-shaped components or part-portions can be influenced in a targeted manner, so as to further improve the dimensional accuracy of the formed component. The material quantity adaptation is set by way of a base-specific material quantity adaptation, a wall-specific material quantity adaptation, a radii-specific material quantity adaptation, and/or optionally a flange-specific material quantity adaptation. A formed component made by the method is also disclosed.
