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.
This case comes from a wind power bearing factory in Tai'an, Shandong. During the production of key wind power bearing components—shaft forgings—the factory has long faced challenges such as insufficient quality stability and tight delivery times. As a professional forging supplier, Jianing Forging provides customized shaft forging solutions, improving product consistency and operational reliability.
Wind power bearings have extremely high requirements for the mechanical properties, fatigue life, and dimensional accuracy of shaft forgings. The customer's original suppliers had shortcomings in raw material purity control, optimization of forging flow lines, and heat treatment uniformity, resulting in some forgings experiencing early failure during use; At the same time, the multi-variety, small-batch production model makes it difficult for suppliers to balance quality and delivery times, seriously affecting customers' complete machine assembly progress.
Jianing Forging addresses customer pain points by establishing a full-process control system from raw material selection, forging process design, heat treatment parameter adjustment, to finished product inspection. Selecting high-purity alloy steel combined with multi-directional forging technology helps grain refinement and rational distribution of streamlines; Optimizing heating and cooling curves through simulation to eliminate residual stress; Each product is subjected to comprehensive ultrasonic, magnetic particle, and dimensional accuracy inspections. The final delivered shaft forgings consistently meet customer specifications in hardness uniformity, tensile strength, and low-temperature impact toughness, while the batch delivery cycle was shortened by more than 15%, earning full customer recognition.
