Dingxi Drive Machinery Closed-Die Forging Case, Gansu

Case Overview

In the Gansu region, a leading manufacturer of drive machinery faced challenges in producing high-strength components with tight tolerances. A specialized closed-die forging solution was implemented at a facility in Dingxi, delivering consistent results for critical driveline parts. The project demonstrated how precision forging can address demanding industrial requirements while maintaining cost efficiency.

Client Challenges

The client encountered several obstacles with conventional forging methods: dimensional inconsistencies leading to costly secondary machining, material waste from flash generation, and extended lead times due to multiple heating cycles. Additionally, the mechanical properties of finished parts often fell short of specifications for heavy-duty drive applications, resulting in reduced service life and higher warranty claims.

Solution Advantages

Our closed-die forging process was tailored to overcome these issues. By utilizing controlled grain flow and near-net-shape forming, the solution reduced material consumption by over 15% compared to open-die alternatives. Precision dies ensured repeatable accuracy within ±0.2 mm, eliminating most post-forging machining. The single-heat operation shortened production cycles by 30%, and optimized cooling schedules improved tensile strength and fatigue resistance. Furthermore, the closed-die design minimized oxidation scale, enhancing surface quality and reducing cleaning steps.
