Case Summary

A building materials equipment factory in Tongzhou, Beijing, needs to purchase annular forgings as key structural components long-term when producing large building materials machinery. The factory's original forging suppliers repeatedly fluctuated in batch consistency, dimensional accuracy, and delivery cycles, affecting the assembly progress of the entire machine and the stability of equipment operation. To support the continuous and efficient operation of the production line, the factory proactively sought more reliable ring forging partners and, after extensive investigation, reached a cooperation agreement with Jianing Forging.

Customer pain points

The main pain points faced by this building materials equipment factory are focused on three aspects: First, the coaxiality deviation between the outer diameter and inner hole of the ring forgings is significant, leading to uneven machining allowances and an increase in scrap rates later on; Second, differences in the mechanical properties of materials between batches affect the safety redundancy of equipment during long-term use; Third, the original supplier's delivery cycle is unstable. Delays during peak seasons often disrupt production schedules, causing capacity losses.

Product advantages

To address these pain points, Jianing Forging focuses on customized services and offers targeted solutions:

• Relatively accurate dimensional control: Using CNC ring grinding technology combined with full-process dimensional inspection helps keep the coaxiality of ring forgings within the customer's drawing ±0.5mm, reducing subsequent machining allowances.
• Stable material properties: Select high-quality alloy steel grades according to customer operating conditions, and optimize heat treatment processes to keep key indicators such as hardness and impact toughness fluctuation within ±5% per batch, meeting long-term load-bearing needs.
• Agile delivery capability: Established dedicated production scheduling channels, shortened the delivery cycle for standard ring forgings from the industry-common 30 days to under 20 days, and reserved equipment capacity for this customer to meet temporary additional order demands.

Ultimately, after switching suppliers, the first-pass pass rate for forgings increased from 86% to over 96%, the equipment assembly cycle was shortened by 15%, and the number of production line shutdowns caused by forging issues was reduced to zero, improving overall operational efficiency.
