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 wind power equipment factory in Shaoxing, Zhejiang, focuses on the production of core components of wind turbine turbines, and its key drive shaft forgings have long depended on external suppliers. During mass production, the factory places high demands on the mechanical properties, dimensional accuracy, and delivery consistency of shaft forgings. As the forging supplier for this project, Jianing Forging provided customized shaft forging solutions.
Wind power equipment has extremely strict requirements for shaft forgings: first, shaft forgings must remain stable under long-term high load and alternating stress conditions. Traditional forging processes are prone to internal uneven microstructure and low fatigue life; Second, customers face multi-variety, small-batch orders, and traditional production line switchovers take a long time and have low efficiency; In addition, some imported forgings have delivery times exceeding six months, seriously affecting project progress. Customers urgently need a solution that balances performance, cost, and delivery cycle.
Jianing Forging addresses customer pain points by providing systematic solutions from three dimensions: materials, craftsmanship, and quality control:
On the material side, selecting high-quality alloy steel and optimizing chemical composition helps ensure the material's hardenability and impact toughness meet wind power standards;
On the process side, multi-directional forging and temperature-controlled forging technologies are used to refine grains and eliminate looseness, resulting in a dense internal structure and rational distribution of flowlines, thereby improving fatigue strength;
On the quality control side, full-process dimensional inspection and non-destructive testing help ensure that each batch of product dimensions is kept within the customer's required ±0.5mm, while lean production scheduling compresses delivery cycles to four to six weeks.
This solution helped the client reduce overall procurement costs by about 15% and resolved the long-standing issue of batch consistency. It has now been supplied continuously for over two years with stable order repurchase rates.
