Abstract
The invention concerns a method of producing a hollow profile with flange. To produce a hollow profile with flange in a simple way and to the requirements of the process, on which profile great enlargements and/or dimensional changes in cross section have to be performed with respect to an initial form to achieve the desired final form, it is proposed first of all to roll-form an initial hollow profile with flange from a sheet bar, which flange is formed by ends of the sheet bar lying parallel against each other, the initial hollow profile having a smaller cross-sectional area and a longer flange than the final form of the hollow profile. After that, the initial hollow profile is shaped into the final form of the hollow profile by exerting a fluidic internal high pressure.
