摘要:
A method for forming hollow profiles is disclosed. In one exemplary method, a hollow profile is guided through a die in a processing direction and fixed by a mandrel such that at the die, the hollow profile has a material flow velocity in this processing direction (2), in which the method the mandrel has a drawing velocity in the processing direction that is greater than the material flow velocity.
