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 ship parts factory in Dongying, Shandong, has long been engaged in the production and processing of marine hardware, mooring parts, and structural components, with stable demand in the die forging sector. However, the factory's original forging suppliers struggled to meet its growing order demands in terms of delivery times, product precision, and batch consistency, affecting overall production line efficiency and assembly quality.
The shipyard faces three prominent issues in actual production: First, large dimensional deviations in die forgings lead to unstable machining allowances and a high defect rate; Second, the internal microstructure density of the forgings is insufficient, and multiple flaw detection failures have occurred during ship inspections; Third, supplier capacity fluctuates significantly, with frequent delivery delays during peak seasons, disrupting manufacturers' production schedules.
To address these pain points, Jianing Forging provided this ship assembly plant with a customized die forging solution. First, by adopting fine die design and multi-station continuous forging technology, the dimensional tolerance of the forging part is kept within ±0.3mm, reducing machining allowance. Second, by optimizing heating specifications and forging ratios, the internal grains of the forgings become finer and the structure denser, with the ultrasonic flaw detection pass rate remaining stable above 99%. Finally, Jianing Forging has established a flexible production scheduling mechanism that dynamically adjusts production lines based on ship assembly plant order priorities, helping to shorten regular lead times by 20% and complete mold changes and production within 24 hours for urgent orders. Currently, this solution has been mass-applied to key components such as anchor chain rings, cable guide holes, and deck bases, with customers reporting a comprehensive cost reduction of about 15% and a significant improvement in assembly efficiency.
