<p>A structural member (1) with a hollow section (2) and a flange (3) at one end is provided by a method for production of such a structural member, comprising forming a blank (23) in the shape of a plate, heating the blank followed by an extrusion process where the blank is pressed between two tool halves (20, 21) forming a radial gap (27) between them thus forming the hollow section (2), and where the flange (3) of the member being formed by co-operating surfaces (28, 22) arranged in the tool halves. The invention also relates to the use of such a member in automotive applications, and a tool for producing such members.</p> |
