World’s largest flow-forming machine The St 650 H 9100 allows high-precision flow forming of tubes over 13 metres long

implementation, the economical production and assembly, as well as the transport possibilities of this high-precision machine, weighing more than 120 tons and measuring more than 30 metres, Leifeld proves yet again its traditional lead as innovative and quality- conscious machine builder; a well-earned reputation dating back to the development of basic flow-forming technology implemented today all over the world. Within the scope of an international invitation to tender, Leifeld succeeded against fierce competition with its convincing innovative power and excellent price-performance ratio. Holger Hansen, CEO Leifeld, takes pride in their technical achievement. “Anji Precision Pipe Manufacturer Co is a renowned customer, enabling us to implement our unique machine concept ST 650 H 9100. The logical further development of the ST series is yet another important milestone in our company history.”

The basis for the successful closing was not least the well-rehearsed collaboration with Leifeld’s Chinese sales partner of many years, Ginweila Science & Tech Co Ltd. The close coordination with the headquarters, technological know-how as well as convincing presentations and clever negotiating skills were crucial factors of success. Wuliangye Anji Precision Pipe Manufacturer Co is a subsidiary of the Wuliangye Group being a modern, Chinese major enterprise. Its focus is the production of plastic products, pharmaceuticals, and tubes. In total, the Wuliangye Group employs more than 30,000 people in several locations in China.

LEIFELD Metal Spinning presents the world’s largest flow-forming machine, the ST 650 H 9100, allowing high-precision flow forming of tubes over 13 metres long. The ST series made by Leifeld captivates through its high-precision forming of rotation- symmetric hollows with both non-varying as well as varying wall thicknesses. With the latest ST 650 H 9100, for the first time, it is now possible to flow form a semi-finished product of higher quality up to 9 metres using forward flow forming technique. This length is even excelled with the backward flow forming technique to more than 13 metres tube length. Werner Hütter, CTO Leifeld: “With these dimensions, Leifeld offers a unique and new machine of the ST series. Due to its incomparable size, we are once again one big step ahead of our competitors.” For the realisation of this machine, entirely new territory, concepts, and detail solutions were elaborated by Leifeld’s experienced engineers. With the technical SIGNIFICANTLY more precision, long- life-cycle and efficiency – this is the result of the development of the new X-RAY 6000 generation. Sikora has designed the new device series, because optimised X-ray technology has specific advantages over alternative measuring technologies regarding quality and reliability during hose and tube manufacture. Moreover, they have the highest potential to considerably save material costs in a long term. The new X-RAY 6000-family is based on the predecessor X-RAY 2000 and had been consequently further developed in details. It is equipped with XLL-(eXtra- Long-Life) X-ray tubes for long operation time. Simultaneously the measuring rate

X-RAY 6000 from Sikora

can be chosen from 1 to 10 Hz. In addition, the use of a universal power supply, which covers all prevalent supply voltages and frequencies, rounds off the technological highlights. The X-RAY 6000 measures the wall thickness, eccentricity, the ovality and diameter with precision. Producers of plastic and composite pipes as well as rubber hoses benefit from the use of the X-RAY 6000 in their lines, as the quality standards for these products

are tremendously high. Sikora AG – Germany Fax: +49 421 48900 90 Email: sales@sikora.net Website: www.sikora.net
