Jinshan Construction Machinery Closed-Die Forging Case, Shanghai

Case Overview

Jinshan Construction Machinery, a heavy equipment manufacturer based in Shanghai, required high-quality closed-die forged components for its structural and mechanical assemblies. A specialized forging company was engaged to deliver precision components that meet rigorous operational demands.

Client Challenges

The client faced several critical issues with existing supply sources: inconsistent material properties led to premature part failure; dimensional tolerances were not maintained across production batches; long lead times disrupted project schedules; and high material waste increased overall costs. These pain points directly affected equipment reliability and profitability.

Our Solution

To address these challenges, the forging team implemented a closed-die forging process with customized die design, optimized material selection, and strict process control. The solution ensured uniform grain flow, improved mechanical strength, and repeatable dimensional accuracy. By refining the production workflow, lead times were reduced by 30% while scrap rates dropped to below 2%. The resulting components met all load-bearing and fatigue requirements, enabling Jinshan to enhance machine performance and reduce maintenance intervals.
