Flowforming technique is a cold plastic forming method, and it is a very advantageous and advanced technique used in the shaping of cylindrical or conical rotationally symmetrical parts with very high precision. In the basic principle of the flowforming technique, the initial wall (wall) thickness of the parts is reduced by the pressing force of the forming relays, and the cylindrical parts are lengthened. Thanks to the flowforming technique, pipes of many different diameters and lengths can be produced very precisely. Flowforming technique is a superior cold forming method and provides significant increases in the requested tolerances and material strength values compared to machining.
