Transforming technologies for tubes from Germany

air suspension components and stabiliser bars. For applications that require combined processes, GFU engineers find solutions to bring these combined processes in line. Most of the GFU- engineered production plants, eg for airbag vessels, are designed as turnkey solutions including tube separation, a bottom closing unit, a neck-down unit, machining equipment, cleaning station and complete tube handling. Well-known GFU customers around the world include Vallourec, Vallourec Saudi Arabia, PT Citra Tubindo, Hunting Energy Services, Tenaris – Fast, Serco, Tube Products of India, Jindal Saw and EFS.

and drive shafts. The high speed end- forming is also used for automobile applications. This technology, developed and patented by GFU, is used for the gas-tight closing of tube bottom shapes as a single-piece solution, and without any welding. The company states that, based on this forming process, high- pressure airbag vessels in millions of cars worldwide are made on GFU end- forming machines. Shock absorber manufacturers use GFU knowledge for closing the tube bottom of their shock absorbers. Flanged shafts, conveyor rollers, pressure accumulators, extinguishers and gas tanks are other examples of products manufactured using GFU technology. Using GFU forging machines many companies produce components such as axle beams (monobloc axles). These machines also find application in manufacturing

GFU (Gesellschaft für Umformung und Maschinenbau GmbH), founded in 1989, is a specialist in transforming technologies for tubes. The company has become an established producer of chipless forming equipment, mostly used for tubes. GFU’s portfolio includes engineering and manufacturing of upsetting presses, swaging or calibration presses, high speed end-forming units, neck down machines, expanding and reducing machines, and forging machines. The OCTG industry uses upsetting presses and swaging presses made by GFU to manufacture drill pipes and casings. Customers around the world are producing oilfield pipes using machines made by GFU. GFU upsetting technologies are also used in the production of automobile components such as tube camshafts (built camshaft), sway bars, stabilisers
