Flow forming

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:

  • 1.4301 / 1.4404 / 1.4841 / …
  • 15-5PH; 17-4PH
  • Sheet steels
  • Heat treatable steels
  • Fine-grained steels
  • Maraging steel
  • Aluminum and aluminum alloys
  • Titanium and titanium alloys
  • Nickel and nickel alloys
  • Tantalum, zircon, niobium


  • Short delivery time
  • Extremly high inside surface
  • Very high accuracy grade
  • Optimum grain structure
  • Possibility for conical offset wall thicknesses
  • Manufacturing of parts with integrated flange
  • Significant revised machanical properties
  • Attractive prices also for small of middle quantities
  • A big range of material even hardened steel and titan
  • Big diameter to length ration

Production possibilities:

  • Round hollows Ø 25 – 650 mm
  • Length up to 6500 mm
  • Wall thickness 0,15 – 20 mm
