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 transmission equipment factory in Suining, Sichuan, has long been engaged in the production and manufacturing of core components of transmission systems, with strict technical requirements in the field of die forgings. When upgrading the production line, the plant needed to find a partner who could provide high-performance die forgings. After extensive evaluation, they finally reached a cooperation agreement with Jianing Forging, adopting a customized die forging solution that improved the limitations of the original process.
The factory encountered the following issues during the use of die forgings: First, traditional forging processes struggled to meet the dimensional consistency requirements for high-precision transmission components, resulting in large machining allowances and serious material waste in later production; Second, some die forgings develop fatigue cracks under long-term high-load operation, affecting the overall lifespan of the equipment; Third, suppliers have long delivery cycles that cannot keep pace with factories' rapid model changeovers. These pain points directly restrict capacity expansion and cost control.
To meet customer needs, Jianing Forging offers the following solutions:
1. Uses fine die forging technology, optimizing die design and forging temperature curves to keep forging blank dimensional tolerances within ±0.3mm, reducing machining volume and improving material utilization by about 15%.
2. Selected high-quality alloy steel and strict post-forging heat treatment processes make the internal structure of the die forgings dense, with grain sizes above grade 7, improving fatigue resistance and meeting the reliability requirements for long-term operation of transmission equipment.
3. Establish a flexible production scheduling mechanism to reduce the delivery cycle for standard die forgings to under 15 working days, and for urgent orders, further shorten it to 7 working days, ensuring customers' production cycles are not affected.
