Huai'an Agricultural Heavy Closed-Die Forging Case, Jiangsu

In the agricultural machinery sector, heavy closed-die forging components must withstand extreme loads while maintaining dimensional accuracy. The following case study illustrates how Jianing Forging addressed a critical manufacturing challenge for a client in Huai'an, Jiangsu.

Case Overview

A leading agricultural equipment manufacturer approached Jianing Forging with a requirement for heavy closed-die forged parts used in high-stress transmission systems. The client needed a reliable supplier capable of producing large, complex geometries with consistent metallurgical properties.

Client Challenges

The client faced several difficulties with their existing forging supplier: inconsistent dimensional tolerances leading to high rejection rates, insufficient mechanical strength in the final parts causing premature field failures, and long lead times that disrupted assembly schedules. Additionally, the parts required strict adherence to material standards and surface quality for corrosion resistance in agricultural environments.

Our Solution

Jianing Forging provided a comprehensive solution through optimized closed-die forging processes. Key improvements included precision die design with multi-stage preforming to ensure uniform metal flow, controlled cooling rates to achieve the required grain structure and hardness, and rigorous non-destructive testing for every batch. The result was a forging with enhanced fatigue life, tighter tolerances (within ±0.5 mm on critical dimensions), and reduced secondary machining requirements.
