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 field of mining machinery, the quality of die forgings directly affects the stability of equipment operation and service life. A mining machinery factory in Guigang, Guangxi, has long faced issues such as insufficient strength of die forgings, poor wear resistance, and unstable delivery cycles, resulting in high equipment maintenance costs and constrained production efficiency. Leveraging its technical experience in die forging processing, Jianing Forging provided the plant with targeted forging solutions, effectively improving its production and operational conditions.
In this cooperation case, Jianing Forging custom-produced key part forgings for a mining machinery factory in Guigang, Guangxi. The factory's original suppliers had shortcomings in internal microstructure density, dimensional accuracy, and batch consistency, affecting the normal operation of core equipment such as crushers and conveyors. Jianing Forging optimizes die design, adjusts forging process parameters, and introduces strict inspection procedures, helping the comprehensive performance of die forgings meet mining requirements.
This mining machinery factory faces the following core issues in actual production: First, early fatigue cracks appear in die forgings under long-term high-load impacts, resulting in high replacement frequency; 2. Uneven hardness distribution on the surface of the forging, leading to premature failure of the wear layer; 3. Large dimensional deviations between different batches of products require additional adjustments during assembly, which extends equipment downtime; 4. Significant fluctuations in delivery cycles of original suppliers, affecting production scheduling. These issues directly increase equipment operation and maintenance costs and limit capacity improvement.
To address customer pain points, Jianing Forging offers solutions from three dimensions: materials, craftsmanship, and quality control. In terms of materials, optimized alloy steel grades are selected to balance strength and toughness; In terms of process, multi-directional die forging technology combined with temperature-controlled cooling processes is used to make the internal structure of the forgings more uniform and ensure stable control of grain size; In terms of quality control, implementing dimensional inspection and ultrasonic flaw detection helps ensure consistency across each batch. At the same time, through reasonable production scheduling and inventory management, Caring shortens standard delivery cycles to under 15 working days, supporting customers' continuous production needs. After batch verification, the service life of the Jianing die forgings used by the factory has increased by about 40% compared to before, with a significant reduction in equipment failure rates and effective control of overall costs.
