Abstract (en)
[origin: EP1702695A2] Shaping of hollow profiled component (1) in a shaping region (U) by heat- and or warm shaping a wall thickening (V) is produced in successive steps and in the shaping region a transition region (W) is formed so that a first section (1a) is produced in the component with an increased diameter (sic) and a second section (1b) of smaller diameter (D2), and the shaping region (U) lies at least partially between these two sections and partially includes the transition (W).
