Introduction of wind turbine forgings

Rich Manufacturing Experiences in the Industry

Wind turbine ring forging is an important part of the wind turbine system. We provide products such as tower connecting flanges, the bottom flanges, the transition piece (TP flanges), MP flanges(monopiles), jackets flange, tower doorframes, forgings for yaw and pitch systems; forgings of gear boxes, wind power generator stator rings and rotor rings and offshore platform forgings and other products. We are a certified supplier of Vestas, Siemens Gamesa and GE, and have sold our products globally. With respect to large megawatt wind turbines, we have successively provided customers with multiple sets of 10MW+ tower flanges such as DEC 10MW, Mingyang 10MW, CSSC 10MW, GE12MW, Siemens Gamesa 11/14MW, Vestas 10MW and so on. And we also have participated in compiling the "Ring Type Forgings of Wind Turbine Generator System" standards developed by National Energy Administration, and the "Precision Forming Technology and Equipment for Wind Turbine Ring Forgings" is listed in China's Torch Plan.
