Case Summary

A certain engineering forklift parts factory in Chongming, Shanghai, has long faced issues such as unstable product performance and long delivery cycles in the supply of wheel forgings. To support the overall safety and reliability of forklift operation, the plant sought partners with suppliers with mature forging processes. Leveraging its technical experience in wheel forgings, Jianing Forging provided customized solutions for this project, helping customers upgrade their production lines.

Customer pain points

The factory's original wheel forging suppliers had the following shortcomings:

• Insufficient internal microstructure density of forgings easily causes fatigue cracks under heavy load conditions;
• Dimensional tolerance control has large deviations, requiring additional adjustments during assembly, which affects production efficiency;
• Single surface treatment processes and uneven wear layer thickness result in wheel lifespans falling short of expectations;
• Bulk supply stability is poor, and supply interruptions often occur during peak order periods, restricting the pace of complete vehicle shipments.

Product advantages

To address these pain points, Jianing Forging optimizes solutions from the following aspects:

• Uses multi-directional die forging technology to improve metal flow distribution, enhancing the overall strength and fatigue resistance of forgings;
• Equipped with high-precision molds and online dimensional inspection equipment, key dimensional tolerances are controlled within ±0.2mm;
• Introducing composite surface strengthening technologies (such as induction hardening + phosphating treatment) to achieve uniform wheel hardness and improve wear resistance by more than 30%;
• Establishing a dedicated stocking mechanism combined with a lean scheduling system helps stabilize the delivery cycle for each batch within 15 days.

Ultimately, the forklift wheel failure rate at the factory dropped by about 40%, and production line assembly efficiency improved by about 25%.
