Custom Medium-to-Large Open-Die Forgings for Heavy-Duty Applications
At Jiangyin Liaoyuan New Energy Co., Ltd., our open-die forging capability focuses on custom medium-to-large forgings for shafts, blocks, and preforms used in demanding industrial applications. Open-die forging allows us to produce sound, high-strength forged blanks with controlled grain flow and structural integrity, providing a reliable foundation for subsequent machining and long-term service performance.
This process is particularly suited for low- to medium-volume, high-value components, where dimensional flexibility, metallurgical quality, and load-bearing capability are critical.
Open-Die Forging Capabilities
Our typical open-die forging capability includes:
-
Finished forging weight: approximately 100 kg to 8 tons
-
Component types: shafts, solid bars, blocks, and custom preforms
-
Typical shaft diameters: Ø100 mm – Ø600 mm
-
Maximum forging length: up to 8 meters
-
Materials:
-
Alloy steels
-
Medium- and high-carbon steels
-
Forgings are produced using hydraulic forging presses, enabling controlled deformation and flexible shaping for both simple and complex geometries. The process ensures favorable grain flow orientation, improved internal soundness, and reduced risk of internal defects compared to cast or fabricated alternatives.
Process Control & Quality Assurance
To ensure consistent quality and reliable performance, open-die forgings are manufactured under a controlled and traceable process, including:
-
Controlled forging reduction ratios to refine grain structure and enhance mechanical properties
-
Process planning tailored to component geometry and load requirements
-
Integrated heat treatment (normalizing, quenching & tempering, annealing, or solution treatment as required) to achieve specified mechanical performance
-
Ultrasonic testing (UT / PAUT) for internal integrity verification
-
Dimensional inspection using CMM and conventional measuring tools
All open-die forgings are produced under a heat number–based full traceability system, ensuring complete documentation from raw material through forging, heat treatment, machining, inspection, and delivery.
Typical Products
Our open-die forging capability supports a wide range of heavy-duty components, including:
Shafts & Rotating Components
-
Generator shafts and industrial motor shafts
-
Planet shafts and transmission shafts for industrial gearboxes
Forged shafts benefit from longitudinal grain flow, improving torsional strength and fatigue resistance.
Solid Forged Blanks & Preforms
-
Solid forged cylindrical blanks for heavy-duty industrial equipment -
Forged blocks and billets for structural and load-bearing components
-
Custom solid preforms designed for subsequent machining
Custom Preforms
-
Near-net-shape preforms designed for subsequent rough and precision machining
Custom preforms help reduce machining allowance, material waste, and overall manufacturing lead time.
Integrated Machining Capability
Open-die forged components can be supplied as forged blanks, semi-machined parts, or fully machined components. The seamless transition from forging to machining reduces dimensional deviation, minimizes handling risks, and improves overall consistency.
Finished examples of forged-and-machined components are available in our Machined Shafts and Machined Blocks product categories.
