摘 要：Forging is a process in which metals are shaped into desired designs by applying compressive forces. This technique is very robust compared to a number of other metal shaping techniques because of the strength acquired by the metal during forging. Some metals are processed hot while others are processed cold. There are a number of forging methods such as closed die, press, and upset forging; open die forging; cold forging; and closed die forging for non-ferrous metals. The Automotive industry is the major end-user of forged products followed by Engineering Machinery and Railway industries.
