Production: In the flowforming process, a blank is first cast which has a very narrow wheel rim base but with significantly greater wall thickness. This blank is then stretched on a cylinder which tapers slightly towards a cone at the top. The blank and cylinder are rotated while three rolling heads, which are also rotating, are pressed against the blank from the outside in a downward motion and at high pressure - around 120 tons. This forces the metal into the desired shape over the cylinder, hence "flowforming", and at the same time compresses it.
