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 manufacturing company in Hengshui, Hebei Province, has long produced various specifications of valve die forgings, with high requirements for internal product tissue density, dimensional consistency, and overall mechanical properties. Previously, this customer used the traditional open-die forging process, which suffered from high material loss, large machining allowances, and low production efficiency, urgently needing a more reliable die forging solution.
The yield of die forgings produced by the original process is unstable, and some batches have internal looseness and uneven distribution of flow lines, leading to frequent parameter adjustments in subsequent machining processes, affecting the overall delivery cycle. At the same time, the raw material utilization rate is about 65%, causing significant cost pressure. The client wanted a supplier who could provide high-precision, highly consistent die forgings while controlling overall costs.
To address the pain points of this valve factory, Jianing Forging uses a multi-directional die forging process combined with fine mold design, allowing metal streamlines to be reasonably distributed along the part contours, thereby improving the density and mechanical properties of the forgings. By optimizing billet volume distribution, material utilization is increased to over 85%, reducing subsequent cutting allowance. Introducing online dimensional inspection during production helps control key dimensional tolerances within ±0.3mm per batch, effectively reducing the number of adjustments required during customer processing. The overall solution helped the client shorten delivery times by about 20% and reduce the overall cost per item.
