SMS Meer plant commissioned

The world´s most powerfull clutch-operated screw press with 35,500 t impact force has gone into production three months earlier than planned at the Wuxi plant (Jiangsu Province, China) of Wuxi Turbine Blade Co. Ltd. (WTB). The press was manufactured and supplied by SMS Meer, Germany. With the new screw press, WTB will be able in future to produce forgings of high-strenght alloys for power station plants and the aircraft industry.

The plant combines the benefit of forging hammer and hydraulic press. Only a small number of strokes are required per forging. This means that the machine guarantees high forming forces with short wokpiece contact time. At the same time the material microstrukture remains homogeneous. WTB thus profits from a high productivity and quality. The heart of the plant is the srew with a diameter of 1,320 mm and a weight of 85 t. The press requires a variable-frequency drive power of only 500 kW. That is 87 % less than a conventional screw press, but with a simultaneous increase in the forming energy. The press is therefore very energy-efficient. Another special feature is the variable impact speed of the dies which enables the customer to forge more-sophisticated parts than to date. "For us the plant has the advantage of being able to meet the growing demands of our customers from the aircraft and power plant industries," says Yan Qi, Managing Director of WTB.
