Ji'an Automotive Heavy Closed-Die Forging Case, Jiangxi

Case Overview

Jianing Forging successfully delivered a heavy closed-die forging solution for an automotive component used in commercial vehicles. The project focused on producing a high-strength, complex-shaped steel part with stringent dimensional tolerances and fatigue life requirements. This case demonstrates the company's expertise in handling large-scale forging challenges.

Customer Pain Points

The customer faced several critical issues: conventional open-die forging could not achieve the required near-net shape, leading to excessive material waste and lengthy machining cycles. The part's complex geometry and high load demands also caused inconsistent mechanical properties in previous suppliers' products. Additionally, the lead time for tooling development and process validation was too long, delaying the vehicle launch schedule.

Solution Advantages

Jianing Forging deployed its advanced heavy closed-die forging process, which utilizes precision-designed dies and controlled thermal cycles to produce parts with superior grain flow and minimal porosity. The solution reduced raw material usage by 18% compared to alternative methods, while the finished component passed all fatigue tests with a safety margin above the specification. The company also shortened the tooling development phase by 25% through simulation-driven die design and iterative prototyping.
