In the field of wind power equipment manufacturing, the quality of forgings in bearing discs directly affects the safety and service life of the equipment. A wind power bearing factory in Fengjie, Chongqing, has long faced issues such as insufficient dimensional accuracy, low material utilization, and unstable delivery cycles during the procurement and processing of disc forgings, affecting overall production rhythm and cost control.

Customer pain points

This wind power bearing factory faces the following challenges with traditional forging suppliers:

• Large dimensional deviations: Some forgings have significant tolerance fluctuations in outer diameter, inner diameter, and height, leading to increased machining allowances and increased material waste and processing time.
• Uneven material properties: Insufficient internal grain density of forgings, local areas with looseness and microcracks, making it difficult to meet the high fatigue life requirements of wind power bearings.
• Long delivery cycles: Suppliers have low scheduling flexibility and slow responses to urgent orders, affecting the overall progress of customer projects.

Product advantages

To address these pain points, Jianing Forging offers customized disc forging solutions, achieving value enhancement through the following measures:

• Fine forging process: Using multi-directional die forging and fine temperature control technology, the dimensional tolerance of forgings is kept within 0.5mm, reducing subsequent processing volume and increasing material utilization by over 10%.
• Quality consistency support: Through full-process heat treatment process optimization and ultrasonic flaw detection, the internal structure of forgings is uniform and defect-free, meeting the requirements of the EN 10204 3.1 standard for wind power bearings.
• Flexible production scheduling and fast delivery: Equipped with multiple large forging hydraulic presses and automated production lines, standard order delivery times shortened by 30%, and urgent orders can deliver samples within 7 days.

This solution has been successfully applied to multiple batches of disc forgings at Chongqing Fengjie Wind Power Bearing Factory. Customers have reported improved forging processing efficiency, reduced overall costs by about 8%, and maintained good consistency in batch products.
