Shanxi Jianing Forging regularly stocks 20#, A105, 45#, and other standard carbon and high-quality carbon steel raw materials. The station has complete real-world cases of carbon steel flanges, shafts, and ring forgings. Carbon steel forgings offer high cost performance and are suitable for manufacturing general industrial equipment.
A valve parts factory located in Harbin, Heilongjiang, has long been engaged in the production of valve components, and has strict requirements for the quality and stability of carbon steel forgings. During its cooperation efforts, the factory encountered issues such as insufficient forging precision and tight delivery times, urgently needing a reliable carbon steel forging supplier. With mature forging processes and stable supply capabilities, Jianing Forging provided this customer with customized carbon steel forging solutions.
This valve accessories factory faced three major pain points during production: First, large dimensional deviations in existing forgings led to uneven processing allowances and a high defect rate; Second, the internal microstructure density of the material is insufficient, with some batches showing microcracks during pressure testing; Third, supplier delivery times are unstable, often affecting assembly progress. These issues directly increase customers' production costs and restrict the continuous improvement of product quality.
To address customer pain points, Jianing Forging offers a system solution from three dimensions: materials, processes, and delivery:
On the material side, carefully selected high-quality carbon steel round billets come with material certificates for each batch to help stabilize chemical composition; On the process side, multi-directional forging and temperature-controlled cooling technologies are used to ensure uniform microstructure and fine-grain refinement of forgings, improving internal density and mechanical properties; On the delivery side, production scheduling has been optimized, reducing the standard delivery cycle to 15 working days, and a dedicated quality inspection process has been established to achieve factory size and ultrasonic inspection. Through these measures, the customer's forging scrap rate has dropped by about 60%, and assembly efficiency has improved by more than 30%.
Jianing Forging not only provides products but also emphasizes technological collaboration. At the initial stage of the project, the technical team was stationed at the factory to coordinate and assist the client in adjusting mold design and forging allowances; During mass production, regular follow-ups and tracking of samples for each batch help maintain long-term quality stability. This case has been cooperating continuously for over three years, with customer satisfaction consistently at a high level.
