Shanxi Jianing Forging finishing gears, valve bodies, and automotive parts fine die forging live case study, intuitively presenting high-precision die forging processing and finished product dimensional accuracy, suitable for automotive, petrochemical, and hydraulic equipment support.
A valve machinery factory in Baoshan, Yunnan, has long purchased various die forgings for the production of core valve components. The factory has many years of experience in valve manufacturing and has strict requirements for dimensional stability, material uniformity, and service life of die forgings.
The previously used die forgings had the following issues:
1. Insufficient dimensional consistency of forgings, resulting in large fluctuations in subsequent machining allowance and a high defect rate;
2. Some forgings have internal structural defects such as looseness and segregation, affecting the pressure resistance of the valve sealing surface;
3. Suppliers have long delivery cycles and insufficient quality stability between batches, affecting the overall continuity of production planning.
To address these pain points, Jianing Forging offers customized die forging services. By optimizing mold flow line design, strictly controlling temperature-controlled forging processes, and multi-pass nondestructive testing, it helps control the dimensional tolerances of each batch of forgings within technical agreements, resulting in dense internal structures and uniform grain sizes. At the same time, Jianing Forging has established a rapid response and production scheduling mechanism, shortening the conventional delivery cycle by about 30%, and cooperating with customers to implement full-process traceability through sampling inspections upon arrival. After switching suppliers, the die forging pass rate improved to a stable level, and the post-assembly processing efficiency of the valve body assembly was significantly improved.
