Case Summary

A transmission machinery factory in Foshan, Guangdong, has long faced challenges in the performance and lifespan of core components in the application of ring forgings. This factory mainly produces high-load transmission equipment, with high requirements for the strength, precision, and consistency of ring forgings. After multiple evaluations, the plant ultimately adopted our annular forging solution, which improved the stability and reliability of equipment operation.

Customer pain points

The transmission machinery factory encountered the following key issues in actual production:

• Traditional forging processes produce ring-shaped parts with internal uneven microstructure and coarse grains, which easily cause early fatigue cracking under high-frequency alternating loads;
• Large machining allowances, long subsequent machining cycles, and severe material waste, increasing overall manufacturing costs;
• Supplier delivery cycles are unstable, with significant quality fluctuations between batches, affecting the assembly progress and finished product rate.

Product advantages

To address the above pain points for customers, Jianing Forging provided customized ring forging solutions:

• By adopting multi-directional forging and temperature-controlled forging processes, the internal structure of the forgings is dense and the flow lines are reasonably distributed, thereby improving fatigue resistance and service life;
• Optimize blank design to keep machining allowances within reasonable ranges, reduce subsequent cutting volume, and improve material utilization;
• A full-process quality traceability system has been established from raw material entry to finished product shipment, supported by stable production schedules, which helps ensure batch consistency and on-time delivery rates.

Through this solution, customers can extend the service life of annular forgings under the same operating conditions, effectively control overall costs, and improve production cycle time and overall machine reliability.
