High-speed end-forming
Our method of flow forming / high-speed end-forming essentially is a modified form of metal spinning. The main difference is, that instead of a single roller, which is spinning a given form, GFU is using a calotte forming die, which is shaping the complete outer form of the work piece. This forming technology can be used for rotationally symmetrical parts only.
Applications
GFU high-speed end-forming is used for applications like:
- Rotor shaft BEV, EV
- Pressure vessels for fire extinguishers
- Airbag pressure vessels
- Accumulators
- Balustrade tubes
- Heating converters
- Designermöbel
- Car and truck shock absorbers
- Gas springs
- Valve tappets
- CO2-vessels
- Gearbox flanges
- Conveyor rollers
- Reducing of single components: A main advantage of the GFU developed and patented high-speed end-forming technology is, that you can form nearly each rotationally symetrical bottom shape without any additional material infeed. Part of this also is the gas-tight closing of tubes without additional material infeed resp. without usage of any additional component. This reduces your stockage cost dramatically.
- Cycle times: The cycle times can be reduced up to 50% verses conventional methods. Using GFU high-speed end-forming technologies combined with a handling system customized for your applications, you can reach enormous increase in productivity.
- Tolerances: Despite of hot treatment we are reaching very tight tolerances, on some parts lenght tolerances with only +/- 0,1 mm. Depending on the kind of product, diameter tolerances below +/- 0,1 mm can be reached.
During the design of your new products you should implement all advantages related to the high-speed end-forming technology. Our R&D departement is at your disposal in case of any question.
