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.
In the field of construction machinery, the quality of carbon steel forgings directly affects the stability of equipment operation and service life. This case focuses on a construction machinery factory in Luoyang, Henan. The company has long relied on traditional forging suppliers, facing issues such as insufficient forging precision, long delivery cycles, and performance fluctuations between batches, which severely limit its overall machine assembly efficiency and end-user reputation.
This construction machinery factory faces three major pain points in the application of carbon steel forgings: First, unstable control of forgings dimensional tolerances, which leads to frequent defects during subsequent machining and increases production costs; Second, insufficient internal microstructural density of forgings, with some products having microcracks or looseness, which affect the fatigue life of key stress-bearing components; Third, suppliers have long delivery cycles and cannot respond flexibly to their production schedules, often leading to material shortage risks.
To address these pain points, Caring Forging provided customized carbon steel forging solutions. First, we optimized the mold design and forging process parameters, leveraging advanced multi-process die forging technology to stably control the dimensional tolerances of forgings within ±0.2mm, thereby reducing the machining allowance for subsequent processes. Secondly, by accurately controlling heating temperature, forging ratio, and cooling speed, the grain fineness and density of forgings have been improved, with an ultrasonic flaw detection pass rate exceeding 99.8%. Finally, Jianing Forging has established an agile production scheduling system, shortening the standard parts stocking cycle to 7 days and enabling rapid response to urgent orders within 48 hours, fully supporting customers' production continuity. Through this comprehensive technical and management upgrade, the customer reduced the scrap rate in subsequent production by about 35%, extended forging service life by nearly 20%, and achieved substantial improvements in supply chain stability.
