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
Advantages:
- 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
