Shanxi Jianing Forging has collected real-world engineering cases of long shafts, short shafts, drive shafts, and marine nuclear power shaft forgings, fully showcasing the forging process of shaft forgings, finished product precision, and practical application scenarios for heavy equipment.
A transmission equipment factory in Changzhi, Shanxi, needed a batch of reliable and high-precision shaft forgings for the construction of heavy machinery transmission systems. The plant sets high requirements for the internal density, dimensional consistency, and long-term service performance of forgings to support the normal operation of its equipment under complex working conditions.
In past production, the factory has repeatedly encountered internal defects such as looseness and shrinkage cavities in traditional forgings, which have led to early fatigue fracture of the drive shaft under continuous load. In addition, ordinary forgings have larger dimensional tolerances, requiring additional machining during assembly, which extends the production cycle. More seriously, some forgings have uneven hardness after heat treatment, causing increased vibration and noise during operation, and frequent downtime for maintenance directly raises operating costs.
Jianing Forging addresses these pain points by providing a complete shaft forging solution. By optimizing the forging ratio and temperature control, the internal microstructure density problem is solved, resulting in forgings without pores or slag inclusions; Combined with fine molds and mature processing technology, dimensional tolerances are controlled within ±0.05mm, enabling direct assembly without secondary processing. At the same time, the use of customized heat treatment curves helps ensure uniform overall hardness, improves fatigue resistance, extends continuous operation cycles for customers' equipment, and significantly shortens maintenance intervals.
