Case Summary

A mining machinery factory in Puyang, Henan, has set strict processing requirements for key transmission components—disc forgings—when producing large mining equipment. This batch of disc forgings must have excellent comprehensive mechanical properties and high dimensional accuracy to support normal operation of the equipment under heavy load and high-speed conditions. Caring Forging was commissioned by them to undertake the custom production task for this batch of disc forgings.

Customer pain points

This mining machinery factory faces the following difficulties in pan disc forging processing:

• Insufficient internal microstructure density of the raw material leads to cracks during subsequent heat treatment of forgings;
• Under traditional forging processes, it is difficult to control the dimensional tolerances of the inner and outer circumference of disc pieces, resulting in a low pass rate for finished products; li>
• Long batch delivery cycles cannot meet the assembly schedule of mining equipment production lines;
• Suppliers respond slowly to process solutions for complex cross-section disc pieces, resulting in high trial production costs.

Product advantages

To address these pain points, Jianing Forging offers a systematic solution:

• It uses a forging process combining multi-directional elongation and upsetting to refine grains, eliminate internal looseness, and improve forging density;
• Introducing CNC grinding ring equipment and fine molds to control dimensional tolerances of the outer diameter, inner hole, and thickness of disc parts within 0.2mm, reducing subsequent machining allowances;
• Optimized heating specifications and forming passes, shortening forging time for single parts by 18% and shortening batch delivery cycles by over 20%;
• We offer full-process technical services from blank drawings and process simulation to first-piece validation, helping customers reduce trial production risks.

After mass production verification, this batch of disc forgings has stable mechanical properties, with a first-pass pass rate of 98%, earning high recognition from customers.
