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 mechanical parts factory in Quanzhou, Fujian, has long purchased ring forgings for key mining equipment components. The factory has strict standards for forging dimensional accuracy, material performance, and delivery times. Due to poor product consistency from the original supplier, subsequent processing parameters are frequently adjusted, affecting production efficiency and finished product pass rates. Recommended by industry clients, the factory established cooperation with Jianing Forging to solve long-standing production pain points through customized ring forging solutions.
The plant encountered three core issues in the use of ring forgings: First, the deviation between the outer diameter and the roundness of the inner hole exceeded the allowable range, leading to uneven residue in subsequent turning processes and an increase of about 15% in machining time; Second, insufficient internal grain structure uniformity in the material, with significant hardness fluctuations after quenching and tempering in some batches, affecting the service life of the final components; Third, delivery times for forgings of multiple sizes and specifications are unstable. The original supplier often experiences delays of 2 to 3 days due to production scheduling issues, disrupting the plant's assembly plan. These pain points directly lead to decreased production line efficiency, rising defect rates, and risks of customer order delays.
To address these pain points, Jianing Forging offers a systematic solution: First, by adopting a fine ring grinding process combined with online dimensional inspection, the outer diameter tolerance of the ring forgings is controlled within ±0.3mm and roundness deviation ≤0.2mm, helping to ensure uniform and stable subsequent machining allowances; second, the forging ratio and heat treatment process window are optimized to stabilize grain size above grade 6, with hardness fluctuation range ≤HRC 2 after quenching and tempering, improving material consistency; In addition, Jianing Forging has established a graded material preparation mechanism, maintaining safety stock for commonly used ring forgings, shortening lead times for regular orders to 10 working days and reducing urgent orders to 5 working days. Feedback from the factory's actual application shows that after switching to Jianing forged products, subsequent processing efficiency improved by 12%, scrap rate dropped by about 8%, and overall procurement costs decreased by about 7%.
