In the field of mining transportation equipment manufacturing, the quality of wheel forgings directly affects the safety and service life of the entire vehicle. A mining transport vehicle factory in Shangluo, Shaanxi, collaborated with Jianing Forging to solve long-standing technical challenges through customized wheel forging solutions, achieving dual improvements in product performance and production efficiency.

Case Summary

The client for this cooperation is a company specializing in the manufacturing of mining transport vehicles in the Shangluo area of Shaanxi. The factory has long supplied heavy transport vehicles to the mining area, with high requirements for the strength, wear resistance, and load-bearing capacity of wheel forgings. Due to the complex working environment in mining areas, existing forgings frequently experience fatigue cracking, deformation, and other issues during use, affecting overall vehicle reliability and maintenance costs.

Customer pain points

Customers face three core issues when using wheel forgings: First, insufficient material strength, which easily causes early cracks under full load and heavy load conditions; Second, poor dimensional consistency of forgings leads to assembly difficulties and affects production line cycles; Third, fatigue resistance cannot meet the demands of continuous mining operations, and frequent replacement of spare parts increases operating costs. In addition, the client's original suppliers had long delivery cycles and could not respond promptly to urgent orders.

Product advantages

To address these pain points, Jianing Forging offers the following solutions:

• Material optimization: Uses alloy structural steel with strict composition control. Through multi-pass forging processes and precise temperature and cold control, the grains of the forgings are refined and the microstructure uniform, with improved tensile and yield strengths to meet the needs of heavy-duty mining conditions.
• Fine forming: Using good mold design and forging simulation technology helps control the dimensional tolerances of each product within reasonable ranges, enabling efficient assembly and reducing rework and adjustment time.
• Process enhancement: Through waste heat quenching + tempering treatment, a stable tempered sorbitite microstructure is obtained, improving fatigue resistance, extending service life, and reducing customer replacement frequency.
• Supply Support: Optimized production scheduling and inventory management, shortening routine order delivery cycles to 15 working days, and enabling urgent production to support continuous operation of customer production lines.

After batch validation, customers reported reduced wheel forging cracking rates, improved assembly efficiency, and effective control of overall vehicle operating costs. Jianing Forging continues to drive product upgrades through technology, helping customers in the mining transportation industry achieve stable and efficient production operations.
