Open Die Forging: Customized High-Quality Forging Solutions
Open die forging is a crucial metalworking process where metal is shaped by applying compressive forces through open dies, allowing for free deformation into various complex shapes. Unlike closed die forging, open die forging is not constrained by die shape, offering high flexibility and adaptability for producing single pieces, small batches, or large forgings.
Advantages of Open Die Forging
- High Material Utilization: Open die forging minimizes material waste, reducing production costs.
- Superior Mechanical Properties: By controlling the forging ratio and deformation, open die forging can refine metal grain structure, enhancing mechanical properties such as strength, toughness, and fatigue resistance.
- High Flexibility: The process accommodates complex shapes and special size requirements, making it suitable for industries like aerospace, petrochemicals, and shipbuilding.
- Custom Production: We offer customized forging solutions tailored to client specifications, ensuring high precision and quality for every product.
Applications
Open die forging is widely used for manufacturing critical components requiring high reliability and performance, such as aerospace engine blades, ship propeller shafts, and oil drilling equipment. Its versatile process characteristics make open die forging indispensable for many high-end manufacturing sectors.
Our Services
With advanced open die forging equipment and a skilled technical team, we are dedicated to providing top-quality open die forging solutions. From material selection and process design to final product inspection, we meticulously control every stage to ensure each forging meets the highest quality standards.

Forged blanks refer to parts blanks made by hot forging process. The forging force can change the shape, size and mechanical properties of the steel blanks. After hot forging, the forged blanks can achieve fine grains and dense structure, and can withstand various heat treatment strengthening processes. Thus, forged blanks are suitable for manufacturing important mechanical parts that need to withstand large tensile stress and bending stress, and have impact loads or large pulsating stress. Usually, the forged steel blanks are made up of carbon steel or alloy steel. We would get the final mechanical parts by the heat treatment and machining the forged blanks.
