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 heavy agricultural machinery factory in Huai'an, Jiangsu, has long faced challenges of insufficient forming precision and low material utilization during the production of large die forgings. In response, Jianing Forging, leveraging years of die forging experience, provided the factory with customized die forging solutions to help enhance product competitiveness and production efficiency.
This heavy agricultural machinery factory mainly produces casting and forging parts for agricultural equipment, with key components such as crankshafts and connecting rods bearing complex alternating loads, requiring high internal microstructural density and dimensional consistency. Jianing Forging undertook its die forging outsourcing project, achieving stable mass supply through process optimization and mold design.
The factory's original forging suppliers had the following issues: First, the mold lifespan was short and frequent changes caused by production cycle fluctuations; Second, large burrs after forging, severe material waste, and persistently high overall costs; Third, deformation after heat treatment exceeds the standard, resulting in large machining allowance and low efficiency. In addition, there are significant fluctuations in mechanical properties between different batches, affecting overall machine reliability.
Jianing Forging has introduced multiple improvement measures to address these pain points: adopting a multi-directional die forging process design to reduce the number of preform preforms and raise material utilization to a reasonable level; Optimizing mold cooling and lubrication solutions extends mold lifespan by about 30%; Controlled cooling technology is introduced during the post-forging heat treatment stage, keeping deformation within 0.5mm and reducing the machining allowance for subsequent processes. At the same time, through process-based quality control, it helps stabilize the performance data of each batch near the core value of customer technical requirements.
