Forging is a process where you shape the metal using localized compressive forces. Currently, industrial forging utilize presses or hammers powered by steam, compressed air, electricity or hydraulics. The main advantage of forging is that it is stronger than an equivalent cast or machined part.
The type of forging is classified according to the room temperature where it was done. Hot forging is done at a high temperature, which is used mainly for metal because it’s easier to shape and less likely to fracture. Warm forging is done at an intermediate temperature, between room temperature and hot forging temperature. Cold forging is when the temperature is below a certain degree.
