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.
In the operation of mining equipment, the performance of die forgings directly affects equipment stability and operational efficiency. A certain mining parts factory has long faced the problem of rapid wear and frequent maintenance of forgings, which not only increases maintenance costs but also affects overall production efficiency. To this end, Jianing Forging conducted in-depth on-site research and, based on the actual working conditions of the plant, customized a set of suitable die forging solutions.
A certain mining parts factory mainly produces key components of crushers, conveyors, and other equipment, with its die forgings operating long-term in high-impact and high-dust environments. The forgings provided by the original supplier had issues such as uneven hardness and susceptibility to fatigue fracture, leading to frequent equipment shutdowns and replacements, which severely restricted the continuity of mining operations.
The prominent issues faced by the plant's die forgings include: first, insufficient material toughness, which easily causes cracks under high stress; Second, poor dimensional accuracy, requiring additional machining during assembly, which extends downtime; Third, the wear layer thickness is uneven, the service life is short, requiring bulk replacement every three months on average, and spare parts costs remain high.
To address these pain points, Jianing Forging has provided the following solutions from material formulation, forging processes, and heat treatment stages: using low-carbon alloy steel and optimizing microalloying ratios to improve the material's impact toughness and fatigue resistance; Multi-directional die forging technology makes metal flow distribution more reasonable, reducing internal defects; Combined with more precise isothermal normalizing treatment, it helps uniform hardness distribution while keeping key dimensional tolerances within 0.2mm. After loading, the delivered forgings have a service life more than twice that of the original parts, effectively reducing the customer's replacement frequency and overall maintenance costs.
