Forging is the process by which metal is heated and is shaped by plastic deformation by suitably applying compressive force. Usually the compressive force is in the form of hammer blows using a power hammer or a press.
Open Die Forgings
Open die forging is a process where the material is not confined laterally as in closed die forging; it is instead performed between two flat dies that have no impression made in them. In open die forging, the movement of the work piece is instrumental to forging the metal into the proper shape. Depending on the capabilities of the forging shop, the size of open die forgings is limited only by the size of the original stock. Philadelphia Forgings offers open die forgings in weights ranging up to 80,000 pounds.
