Forging is one of the oldest known metalworking processes. It is the process for shaping metal by using compressive forces and increasing its strength by hammering or pressing processes. Forging parts can range in weight from less than a kilogram to 170 metric tons. Forged parts usually require further processing to achieve a finished component. Forging results in metals that are stronger than cast or machined metal parts. This is because during forging the metal's grain flow changes into the shape of the part, making it stronger. Many metals are forged cold, but iron and its alloys are gnerally forged hot. Forging was done historically by smiths using hammer. In modern times, industrial forging is done either with presses or with hammers powered by compressed air, electricity, hydraulics or steam.
Through out the forging process, good quality forging elements are used, so that the resulting product or tool is of high quality. Most common forging parts are hammer, anvil, Chisel, Tongs, Fuller, and Hardy.
