Forgings : Drop Forging

Forging is a metalworking process in which an impact device is used to deliver compressive force to areas of the metal in order to shape it. Forging was originally done manually with a hammer and anvil, however industrial forging machines now use hydraulics, compressed air, or other methods to drive mechanical hammers, or presses, into the surface. Drop forging refers to the process in which the heated metal is placed into the forms, known as the die and punch. A large, heavy, mechanically-driven hammer is then dropped into the die, forcing the softened metal into the mold cavities of the die and punch.
