Shanxi Jianing Forging has gathered real-world cases of wind power flange rings, ring gears, bearing rings, roller rings, and other ring landings, with a complete range of finished forging products for carbon steel, stainless steel, and alloy rings, providing reference for product selection and non-standard solutions.
A transmission machinery factory in Zunyi, Guizhou, needs to procure high-quality annular forgings long-term for key transmission component manufacturing. The factory's products are used under heavy load conditions, requiring high dimensional accuracy, internal structural uniformity, and fatigue life of forgings. As a ring forging supplier, we collaborate with customers to provide customized solutions tailored to their specific process requirements.
The original forging suppliers at this transmission machinery factory often encountered the following issues during bulk supply: First, the ovality of the ring forgings was too large, leading to uneven machining allowances and an increase in defect rates; Second, fine cracks and loose microstructures inside the forging, which can easily trigger early failure during operation; Third, delivery times are unstable, with multiple production bottlenecks affecting customers' production schedules. These pain points directly restrict the reliability and delivery efficiency of customers' products.
We provide comprehensive solutions tailored to customer needs from three dimensions: materials, processes, and inspection. On the material side, select alloy steel billets with higher purity, strictly controlling the content of impurities such as sulfur and phosphorus; On the process side, multi-heat forging + fine rolling expansion technology is used to keep the wall thickness difference of ring forgings within 0.5mm, and internal grain size reaches above grade 6; On the inspection side, ultrasonic flaw detection, magnetic particle inspection, and full dimensional inspection processes are provided, helping each product meet drawing requirements. At the same time, by optimizing production cycles and establishing safety stock mechanisms, delivery cycles have been shortened by 30%, supporting customers in continuous production.
After introducing our ring forgings, the production line scrap rate dropped by about 15%, and the fatigue life of transmission components in bench tests increased by more than 20%. Stable quality and delivery help customers reduce overall costs and gain end-user recognition. This case also demonstrates our full-process control capability in the field of ring forgings, from materials to finished products.
