In the field of heavy machinery manufacturing, the quality of wheel forgings directly affects the forklift's load capacity, service life, and operational safety. Jianing Forging provided a customized wheel forging solution tailored to the actual needs of a forklift heavy factory in Wuwei, Gansu, assisting customers in upgrading production processes and consistently improving product performance.

Case Summary

The client for this cooperation is a heavy industry enterprise in the Wuwei area of Gansu, specializing in the manufacturing of complete forklifts. During mass production, the factory needs to purchase large-tonnage forklift wheel forgings in bulk, placing high demands on strength, fatigue life, and dimensional consistency. Jianing Forging, with its mature forging processes and strict quality control system, has become its core supplier.

Customer pain points

Customers have long faced the following issues under the existing supply system: some forgings have insufficient internal microstructure, causing fine cracks in wheels under heavy load conditions; Large dimensional deviations between different batches of forgings increase subsequent machining and commissioning costs; Additionally, inadequate treatment of oxide scale residue on the surface of forgings affects the final coating adhesion. These issues not only reduce production line efficiency but also increase after-sales quality risks.

Product advantages

To address these pain points, Jianing Forging offers targeted solutions from three dimensions: materials, processes, and inspection:

• Material optimization: Selecting high-quality carbon structural steel and strictly controlling alloy composition ratios help the forging body maintain stable comprehensive mechanical properties.
• Forging process: Using closed-die forging combined with multi-directional forging technology, the grain structure is refined, internal loose defects are eliminated, and the density and flow line distribution of the forging is more reasonable.
• Dimensional accuracy control: Introduces fine molds and process temperature control systems to keep key dimensional tolerances within ±0.5mm, reducing processing allowances in subsequent processes.
• Surface treatment: Before leaving the factory, forgings undergo unified shot blasting and rust removal, achieving a surface cleanliness of Sa2.5 grade, which improves subsequent coating quality.

After batch supply validation, this solution helps customers raise the qualification rate of wheel forgings to a high level. At the same time, improved dimensional stability significantly shortens production line adjustment time, effectively controlling overall production costs. Jianing Forging will continue to help customers build more competitive supply chain systems with stable and reliable products and responsiveness.
