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 bearing factory in Bengbu, Anhui, has long faced issues of insufficient internal microstructural density and dimensional consistency fluctuations when producing high-precision bearing shaft forgings. The factory's original process was prone to microcracks during forging, resulting in unstable product lifespan and a high rework rate. Based on years of experience in shaft forging manufacturing, Caring Forging provided a customized precision forging solution.
The core pain point of this bearing factory is that the shaft forgings undergo significant deformation during subsequent turning and heat treatment stages, with some batches showing micro-surface cracks, directly affecting the bearing rotational accuracy and service life. At the same time, traditional die forging processes have low raw material utilization rates, increasing cost burdens. The plant urgently needed a supplier capable of balancing material flow, grain refinement, and dimensional tolerances.
To address these pain points, Jianing Forging has optimized forging ratios and heating curves, introducing multi-directional controllable forging technology to distribute metal flow lines evenly along the axis, effectively eliminating internal looseness. Through fine mold design and cooling process adjustments, roundness tolerances are controlled within 0.05mm, reducing surface roughness to Ra3.2. Additionally, using analytical simulation software for pre-study of each batch of forgings helps ensure consistency during mass production, reduces rework rates to below 1%, and saves customers about 12% in material consumption.
