Abstract
A method for producing a component made of metal, particularly for a head bearing housing of a spring strut. The component comprises a base part and a flange that extends away therefrom. The flange comprises a substantially tubular portion having a first diameter and a collar-type rim portion that adjoins the tubular portion. The free edge of the tubular portion has a second diameter that is greater than the first diameter of the tubular portion. A raw component is provided comprising a base part and a cylindrically tubular portion having a third diameter that is at least greater than the first diameter. The third diameter of the cylindrically tubular portion is reduced to the first diameter at a distance from an edge of the tubular portion by forming by means of a forming tool that is applied to the outside of the tubular portion and that acts approximately radially toward the longitudinal center axis, in such a way that the collar-type rim portion is constituted.
