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 mining machinery factory in Guiyang, Guizhou, focuses on manufacturing mining equipment, and its key components require high-precision ring forgings. The factory encountered multiple technical challenges during the procurement process, but Jianing Forging, leveraging its solid process capabilities, provided customized solutions that improved equipment operational stability.
This mining machinery factory is located in Guiyang and mainly produces mining equipment such as crushers and conveyors. Ring forgings are used in core areas such as slewing bearings and gear rings, requiring high dimensional accuracy, material strength, and batch consistency. As a professional supplier of ring forgings, Jianing Forging undertook multiple batches of production tasks for the plant.
During the initial cooperation, the client faced the following difficulties:
1. Large dimensional deviations: Some suppliers deliver forgings with tolerances exceeding the drawing requirements, resulting in insufficient machining allowance or assembly difficulties.
2. Uneven internal structure: After ultrasonic testing, issues such as coarse local grains and band-like segregation may occur, affecting fatigue life.
3. Unstable delivery cycles: Due to the impact of raw material supply and production scheduling, order delivery is often delayed, disrupting customers' production plans.
To address these pain points, Jianing Forging has implemented multiple improvement measures:
1. Introduces precision forging dies and CNC ring grinding technology, controlling the inner and outer diameter tolerances of ring forgings within ±1.5mm to meet customers' stringent precision requirements.
2. Select high-quality alloy steels (such as 42CrMo, 35CrMo) and apply normalizing + tempering pretreatment to achieve grain size above grade 6, eliminate banded structures, and improve overall mechanical properties.
3. Establish dedicated fast lanes to optimize forging heating parameters and heat treatment cycles, shortening routine delivery times by 20% and helping customers start production on time.
Ultimately, the mining machinery factory recognized the quality and service of Jianing's ring forgings, and the two parties established a long-term and stable cooperative relationship.
