In Shenyang, Liaoning, a heavy machinery factory has long relied on imported ring forgings for key structural components. Due to long import cycles, high costs, and supply chain instability, the factory often faces production planning delays and cost control challenges. At the same time, some domestic suppliers' products cannot meet the demanding requirements of precision and mechanical performance, leading to higher equipment failure rates. To address these issues, the plant began seeking localization partners with stable supply capabilities and technical strength.

Customer pain points

This heavy machinery factory mainly faces three challenges: First, the delivery cycle for imported ring forgings is as long as 4~6 months, seriously affecting production scheduling; Second, the procurement cost per piece is about 30% higher than similar domestic products, continuously squeezing profit margins; Third, there are significant performance fluctuations between different batches, with some batches exhibiting uneven hardness and loose internal structure, leading to early equipment failure after assembly.

Product advantages

Jianing Forging offers customized ring forging solutions tailored to customer needs, with the following specific advantages:

• Stable delivery cycle: By optimizing forging processes and increasing stock inventory, standard delivery times are shortened to 45 days, and urgent orders can be compressed to 30 days, supporting customer production continuity.
• Cost optimization: Using high-quality domestic alloy steel billets combined with more precise control of cutting and forging allowances, material utilization is increased to over 82%, with unit cost reduced by about 25% compared to imported solutions.
• Quality consistency: Equipped with ultrasonic flaw detection, magnetic particle testing, and mechanical performance testing equipment. Each batch of products undergoes one test according to customer technical agreements, helping to keep key indicators such as hardness, tensile strength, and elongation within ±5%.
• Process adaptability: Based on the load spectrum and installation dimensions provided by the customer, the grain flow direction and fiber microstructure distribution of the forging are adjusted, increasing the fatigue life of the ring forgings to more than 1.2 times that of the original imported parts.

After batch application validation, after adopting Jianing's ring forgings, the equipment failure rate dropped by about 18%, the overall manufacturing cost per heavy machinery was reduced by 12%, and long-term recognition from the customer's technical department was achieved. Currently, this solution has been promoted to other production lines in the same industry and has become one of the typical cases of domestic substitution for import.
