Types of forging processes forging industry association. Level of throughforging and basic forging operations. With the use of mechanical manipulators, a work piece is compressed and rotated in a series of steps eventually forming the metal into a cylindrical part. It is usually referred as hot pressing, and is carried out either using hydraulic presses or mechanical crank type presses. There is little restriction to metal flow and as the repeated hammer blows reduce the cross section of the workpiece, its length can increase. Opendie forging is a drop forging where a hammer strikes and deforms the metal, which is placed on a hammer anvil or a press bed. Forging process animation by basic engineering youtube.
