Methods – Reverse FlowformingReverse Flowforming is utilized to produce a component with two open (unrestricted) ends such as a tube. Once the preform is placed on the mandrel, it is pushed all the way to the left side against the drive ring at the end of the mandrel. Like Forward Flowforming, the carriage also moves in a right to left direction. As the axial thrust of the rollers applies force to the right of the preform, the metal is pushed into and entrapped by a series of serrations on the face of the drive ring. This assures the necessary rotational drive of the preform during the process cycle. With the carriage traveling left, the flowformed metal moves to the right, under and in the opposite direction of the rollers.
