The Shanxi Jianing Forging Forging Train Wheel, Mine Overhead Wheel, and Heavy-Duty Overhead Wheel Forging Project features mature forging technology for high-strength wheels, excellent load-bearing performance, and suitable for heavy-duty conditions in rail transit and mines.
A mining truck machinery factory in Weihai, Shandong, has long been engaged in the production and assembly of heavy mining dump truck components. Its wheel forgings are a key link in vehicle load-bearing capacity and safety. During the ram-up phase, the plant faced issues such as unstable forging supply and large performance fluctuations between batches, so it sought forging suppliers capable of stable batch delivery. With mature forging techniques and strict process control, Jianing Forging has become a long-term supplier of wheel forgings for the plant.
This mining truck machinery factory originally relied on multiple small-scale forging factories to supply wheel forgings, with pain points focused on three areas: First, products from different suppliers had differences in hardness and metallographic structure, resulting in a low wheel dynamic balance pass rate after assembly; Second, delivery cycles are irregular, with frequent supply interruptions during peak seasons, affecting vehicle rollout plans; Third, some forgings exhibited early fatigue cracks under relatively high strength conditions in mining areas, increasing after-sales maintenance costs. Customers urgently need a wheel forging solution that supplies stable, consistent performance, and reliable lifespan.
To address customer pain points, Jianing Forging's wheel forging solutions are optimized from three dimensions: material, process, and inspection. High-quality alloy structural steel is selected as material, with impact toughness improved through fine-tuning of composition; The process uses closed die forging + fine roller expansion to reduce internal defects; The inspection process introduces online hardness sorting and ultrasonic flaw detection, helping each product meet the drawing requirements. The final delivered forgings achieved a dynamic balance pass rate of over 98%, with on-time delivery rates maintained above 95%. Actual measurements in the mining area show that the average service life of forgings has been extended by about 30% compared to the original plan.
