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.
In the field of transmission component manufacturing, shaft forgings are key components, and their quality directly affects the stability and service life of equipment. A transmission parts factory in Xingtai, Hebei, has long been engaged in processing various shaft products. Recently, it encountered issues of inconsistent material properties and difficulties in controlling machining allowances in the supply of shaft forgings. In response to this situation, Jianing Forging, leveraging its professional experience in forging, has provided customers with customized shaft forging solutions, effectively improving production pace and finished product quality.
During the procurement of shaft forgings, this transmission parts factory has always faced two core challenges: First, the internal microstructure uniformity of different batches of forgings fluctuates greatly, making it difficult for subsequent heat treatment to stably meet strength and toughness standards; Second, the dimensional allowance design of forging blanks is not reasonable enough; excessive allowance in some areas leads to material waste, while insufficient allowance in some areas increases machining risks. In addition, traditional suppliers have longer delivery cycles, making it difficult to meet customers' flexible production needs for multiple varieties and small batches.
Jianing Forging has optimized these pain points from three dimensions: process design, material control, and delivery response. In terms of process design, a multi-pass pre-forging and final forging scheme is adopted, combined with a more accurate mold cavity design, making the flow line distribution of the forgings more reasonable and improving the internal microstructural density. In terms of material control, we strictly select alloy steel raw materials, and each batch undergoes chemical composition and low-magnification microstructure testing to ensure consistency in incoming materials. At the same time, by establishing a flexible scheduling mechanism, the forging cycle for standard products is shortened to under 7 working days, providing reliable support for customers' urgent orders. After mass trials, the transmission parts factory reported that the scrap rate of shaft forgings dropped by about 20%, machining efficiency increased by 15%, and overall costs were effectively controlled.
