open die forging process
What is Open Die Forging?
Open die forging, also known as free forging, is a robust industrial process where a metal workpiece is shaped by repeated, controlled compression between two flat or simple-contoured dies. Unlike closed die forging, the metal is not entirely confined, allowing it to flow freely except where it contacts the dies. This method is ideal for creating large, high-strength, and custom-shaped components with superior mechanical properties.
The process enhances the grain structure of the metal, refining it and aligning it to the part’s contours. This results in forged components with exceptional impact strength, fatigue resistance, and structural integrity, making them a preferred choice for critical applications across various industries.
The Step-by-Step Open Die Forging Process
Our state-of-the-art open die forging process is meticulously controlled to ensure consistency and quality in every part we produce, from prototype to high-volume batches.
Material Selection & Billet Preparation: The process begins with selecting the appropriate raw material—a cylindrical or rectangular billet. We are experts in forging a wide range of materials, including:
Carbon Steel Forgings: For high-strength and durable components.
Stainless Steel Forgings: For superior corrosion and heat resistance.
Aluminum Alloy Forgings: For lightweight yet strong parts with excellent conductivity.
Heating: The billet is heated to a precise “forging temperature” in high-capacity furnaces. This heating makes the metal malleable, allowing for efficient deformation without cracking.
Forging Operation: The heated billet is placed on the lower die of a powerful hydraulic or mechanical press. The upper die then applies compressive force, and skilled operators manipulate the workpiece through a series of movements—rotating, lifting, and shifting—to achieve the desired shape, such as shafts, rings, discs, or blocks.
Secondary Processes (In-House): Once the primary forging is complete, our integrated capabilities ensure a seamless transition to finishing.
Machining: Our powerful machining capacity allows us to perform precision machining on all our forged parts. We can achieve tight tolerances, create complex geometries, and deliver ready-to-assemble components.
Heat Treatment: Parts are often heat-treated (annealing, normalizing, quenching, and tempering) to achieve specific mechanical properties like enhanced hardness or toughness.
Surface Treatment: We offer galvanizing services to provide a protective zinc coating, significantly improving corrosion resistance for steel components. Other surface treatments are also available.
Inspection & Quality Assurance: Every forged component undergoes rigorous inspection, including dimensional checks, visual examination, and non-destructive testing (NDT) to guarantee it meets all customer specifications and industry standards.
