Case Background

A construction machinery parts factory in Longyan, Fujian, has long purchased die forging products for assembly of key components such as loaders and excavators. The factory's original suppliers are increasingly unable to meet the capacity expansion needs in terms of delivery times, product consistency, and overall costs, urgently needing to bring in more reliable forging partners.

Customer pain points

This parts factory faces three prominent issues during the use of die forgings:
- Production schedules are tight, with the original supplier's on-time delivery rate below 85%, frequently causing production line shutdowns and waiting for materials;
- Different batches of forgings fluctuate in dimensional accuracy and mechanical properties, requiring additional quality inspection and screening, increasing hidden costs;
- Low material utilization (about 72%) and low recycling value of scrap, with overall manufacturing costs remaining high over time.

Solutions and product advantages

To address these pain points, Jianing Forging customized a precision die forging solution for this construction machinery parts factory:
1. Optimized mold runner and flash groove design, increasing material utilization to over 91% and reducing waste by about 26%.
2. Introducing closed-loop temperature control and multi-station linkage forging systems helps balance internal stress in forgings of the same batch, keeping hardness differences within ±2 HRC, eliminating the need for secondary sorting.
3. Adopted mature segmented production scheduling and rapid die change processes, compressing the delivery cycle of standard forgings to 70% of the industry's usual cycle, achieving a 12-month on-time delivery rate of 99.2%.
4. Full-size inspection reports and fatigue test data are provided, allowing customers to assemble directly without separate on-site inspection.
