Langfang Hydraulic Heavy Closed-Die Forging Case, Hebei

Case Overview

In the Langfang hydraulic heavy closed-die forging project, our company, a specialized forging manufacturer, successfully delivered a set of large-scale closed-die forgings for a hydraulic system application. This case exemplifies the capability to handle complex, high-strength components with tight tolerances, serving industries such as heavy machinery and energy.

Customer Pain Points

The client faced several critical challenges: their existing forging process could not achieve the required dimensional accuracy for the closed-die design, leading to excessive material waste and post-processing costs. The high weight and complex geometry of the part also caused uneven material flow, resulting in internal defects and reduced fatigue life. Additionally, the long lead time from traditional open-die forging methods failed to meet the project schedule.

Product Solutions

To address these pain points, our team implemented a customized closed-die forging process using advanced hydraulic presses with precise temperature control and multi-stage deformation. The solution provided near-net shape components with a dimensional tolerance within ±0.5 mm, eliminating secondary machining needs. Optimized die design ensured uniform material flow, reducing internal porosity and improving mechanical properties. The production cycle was shortened by 30% compared to conventional methods, allowing the client to meet their delivery deadline without compromising quality.
