Open Die Forging

Open die forging is a metalworking process that involves shaping metal by striking it with hammers or presses between two flat dies, or between a flat die and a backer. Unlike closed die forging, the dies in open die forging do not completely enclose the workpiece, allowing for greater flexibility in the shape and size of the final product.

Open die forging is commonly used to produce significant, custom-shaped components such as gears, shafts, and rolls and smaller components like hand tools and fasteners. The process offers several benefits, including improved mechanical properties, better dimensional accuracy, and reduced lead times compared to casting and machining.

To produce forgings using open-die forging, the workpiece is first heated to a temperature that becomes pliable and can be shaped by forging. The workpiece is then placed between the dies and struck with a hammer or press, gradually shaping it into the desired form. The forging process is typically repeated several times to achieve the desired final shape and size.

In conclusion, Open die forging is a versatile metalworking process that is capable of producing a wide range of custom-shaped metal components with improved mechanical properties and dimensional accuracy.
