Abstract
Cold forming process for a hollow profile (1) with two internal profile sections (2, 3) in angular alignment separated by an internal shoulder (4), wherein the profile sections (2, 3) are formed successively by pressing a blank (10) over corresponding mandrel profiles (12, 16), a first profile section (2) and/or reference profile (19) being formed in the first operation which is used to align the angular position of the second mandril profile (16) for forming the second profile section (3) in the next operation.
