In the field of shipbuilding heavy industry, the quality of forgings in key structural components directly affects the ship's construction cycle and operational reliability. The disc forging project provided by Jianing Forging for a shipbuilding heavy factory in Tongren, Guizhou, successfully validated our technical strength and service capabilities in processing large-scale special-shaped forgings.

Case Summary

This project serves a heavy industry enterprise engaged in shipbuilding and repair in the Tongren area of Guizhou, with its main demand for large shipboard disc forgings. This forging is used at key connection points in ship power systems, meeting multiple stringent requirements such as high load-bearing capacity, corrosion resistance, and long service life, with extremely high requirements for material purity, forging process, and heat treatment precision.

Customer pain points

Customers face the following core issues in collaboration with existing suppliers: First, insufficient dimensional accuracy of forgings, leading to misalignment during assembly and high rework rates; Second, the internal microstructure density of the material is unstable, affecting fatigue strength; Third, the delivery cycle is relatively long, which drags down the overall shipbuilding progress; Fourth, for complex-shaped disc forgings, there is a lack of mature shape control technology, making defects such as cracks and folding prone to occur.

Product advantages

To address these pain points, Jianing Forging offers a complete solution:

• Fine forging process: By combining multi-directional die forging with finite element simulation, we optimize billet design and forging steps, helping to keep the dimensional tolerances of disc forgings within customer requirements and reducing subsequent machining allowances.
• Refined heat treatment: Based on the thickness and material characteristics of disc forgings, segmented temperature control and rapid cooling processes are developed to refine internal grains and uniform microstructure, with comprehensive mechanical properties meeting classification society standards.
• Full-process quality control: From raw material re-inspection upon arrival to non-destructive testing of finished products, traceable data archives are established to effectively prevent hidden defects from entering the next process.
• Customized delivery service: Production schedules can be flexibly adjusted according to customers' shipbuilding milestones, reducing unnecessary waiting times to help forgings be delivered on time or even ahead of schedule.

Ultimately, this batch of disc forgings passed customer acceptance in one go and was assembled with zero rework, significantly helping the customer improve shipbuilding efficiency and laying a solid foundation for long-term cooperation between the two parties.
