Closed Die Forging WeldaloyClosed Die Forging. The closed die forging process (also called impression die forging) uses pressure to force or compress a piece of metal to fill an enclosed die impression of a predetermined shape and form. Depending on the products size, shape, or specifications, several impression dies can be used to form the finished product.
The process simply utilizes the force from a closed-die forging hammer or press, and heat, to deform the metal to fill the die impression or mold. The Advantage of Flash in Closed-Die Forging Where both die forgings can result in a thin layer of flash (excess material squeezed out during the die forging process) the closed-die process uses the flash to its advantage. Closed Die ForgingClosed die forging is operated under two tooling dies:a stationary die (anvil) and a moving die (hammer). Both dies contain an impression of the desired part shape. The moving die presses down onto the stationary die and the metal workpiece and causes the metal to flow into every part of the die and take its shape.
