Jiangsu Rongfa specializes in manufacturing drive shaft and gear drive shaft forgings, widely used in automotive transmission systems, construction machinery, wind turbine gearboxes, industrial reducers, mining machinery, and special vehicles. As key components for power transmission, drive shafts require high strength, high toughness, and excellent fatigue resistance; gear drive shafts must simultaneously meet stringent requirements for torsional strength, fatigue resistance, and dimensional stability. With an integrated production line covering forging, heat treatment, machining, and inspection, the company ensures dimensional accuracy and internal quality. All products undergo rigorous NDT and mechanical property testing, with complete material traceability. Products are widely applied in heavy truck transmission systems, construction machinery drive axles, wind turbine gearboxes, rolling mill equipment, cement mills, tunnel boring machines, agricultural machinery, and large cranes, meeting various power transmission needs with reliable quality.
