Flow forming is a modern forming technology of seamless tubular components. The tooling is being brought to rotation with a work piece and is being loaded with three rollers so that the material can flow in axial direction. Thus a long thin-walled tube, which is being characterized by an improved surface and a very high precision, is being produced of a short thick-walled tube.
In general nearly all metallic materials can be formed by flow forming as, for example:
