Hebei Dongan Precision Manufacturing produces wedge-rolled ladder/stepped shaft blanks and rough-turned rotary shafts, delivering high precision with efficient cross-wedge rolling.
Hebei Dongan Precision Manufacturing Co.,Ltd specializes in producing ladder/stepped shaft blanks and rough-turned rotational shafts, including gear shafts, camshafts, oil pump shafts, semi-axle shaft sleeves, hollow shafts, and related rotary axial blanks and forgings.
The company’s core capability is cross-wedge rolling. Heated rods are formed between two synchronized rotating wedge molds to achieve radial compression and axial extension, producing ladder shaft components with high productivity, high precision, and efficient material utilization.
With dedicated wedge rolling lines supported by induction heating, pressing, rolling, and turning processes, the factory supplies shaft blanks for applications such as transmissions, engines, hydraulic systems, electric tools, and engineering machinery. The company also maintains in-house testing and analysis capabilities across chemical analysis, metallography, hardness testing, and ultrasonic inspection, supporting stable quality and process control.
Innovation is supported through a cross-wedge-rolling technology R&D lab and long-term cooperation with an efficient rolling parts research and extension center. The company operates under a management philosophy of good faith and a quality policy focused on market needs, customer satisfaction, continuous improvement, and the pursuit of excellence.
