Project Background

A hydraulic equipment factory in Mianyang, Sichuan, has long faced issues such as uneven internal organization and large dimensional deviations in the production of ring forgings, resulting in a low product pass rate and affecting overall delivery efficiency. The company urgently needed a ring forging solution that could stably control forging accuracy and improve material density.

Customer pain points

Customers mainly encounter the following difficulties in traditional forging processes: First, poor matching of heating temperature and deformation rate leads to coarse internal grains in the forging; Second, mold wear is fast, resulting in poor dimensional consistency of finished products; Third, there is large machining allowance for subsequent processing, resulting in serious material waste. These issues directly increase production costs and rework cycles.

Product advantages and solutions

To address these pain points, we offer customized ring forging solutions:

• Temperature-Deformation Coordinated Control: By optimizing heating curves and deformation parameters, metal flow becomes more uniform, effectively refines grain structure, and enhances the overall mechanical properties of forgings.
• High-precision mold design and maintenance: Using high-temperature, wear-resistant mold materials, combined with regular online calibration, helps maintain stable dimensional ranges even after multiple forgings.
• Near-net forming process: Reduces allowance design to bring forgings close to the final shape, thereby lowering subsequent processing volume and saving materials and labor time.

These measures helped the customer increase the pass rate of ring forgings to over 98%, reduce the overall cost per piece by about 15%, and shorten delivery cycles by 20%.
