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 shipbuilding, shaft forgings, as key transmission components, have a quality that directly affects the stability and safety of the entire ship's operation. Jianing Forging once provided custom shaft forging solutions for a ship equipment factory in Wuqing, Tianjin, helping customers solve technical challenges in production.
This ship equipment factory has long been engaged in the production of marine supporting equipment and has strict requirements for the material properties, machining precision, and delivery times of shaft forgings. In this collaboration, the customer required a batch of relatively high-strength shaft forgings for ship propulsion systems, requiring uniform material, flawless surfaces, and the ability to withstand long-term operation under complex sea conditions.
Customers encounter multiple challenges during early procurement: first, conventional shaft forgings on the market struggle to meet classification society certification standards in terms of material density and heat treatment uniformity; Second, some suppliers cannot balance the machining precision and surface finish of large-size shaft parts; Third, unstable delivery cycles have led to frequent adjustments to customers' production plans. These pain points directly affect the quality of customers' products and project schedules.
To address these pain points, Jianing Forging has optimized the entire process from material selection to process implementation: selecting high-quality alloy steel billets and enhancing material density through multi-directional forging technology; Uses segmented temperature-controlled heat treatment technology to ensure uniform hardness inside and outside the shaft parts; Combined with fine turning and polishing processes, dimensional tolerances are controlled within 0.05mm, with surface roughness reaching Ra1.6μm. At the same time, relying on a stable production scheduling and quality inspection system, we shorten routine delivery cycles by 15%, supporting customers in continuous production.
The final delivered shaft forgings passed third-party testing, with mechanical properties, non-destructive testing, and dimensional accuracy all meeting marine standards, earning recognition from the client's technical team. Subsequently, both parties have established long-term cooperation.
