Forging principally based on the concept of generating approving geometric alterations in the metal with the aid of compression forces. Thus, forging, manufacturing process of shaping metals by means of compressive forces. Since the practice of metal forging carried out by Indian forging manufacturers build the strong metal parts, which are practical in different industrial sectors dealing with heavy duty machines. Forging process requires exact familiarity in the required kind along with skill. Adopt international quality standard as ISO that strive for strengthened and accurate mechanical part forged with precision. Improved strength of the material has a tendency to reshape it composition under heavy pressure, closing unfilled voids in the metal. Hence, it can be used to prevent water leakages as they can endure high pressure and are corrosion resistant. Any structure made out of a forged metal has structural reliability and high safety factor.
Various forging techniques are implied to get the desired result.
Cold forging is performed at room temperature whilst hot forging is done above recrystallization temperature. Open die and closed die forging, the former is placed in an open die, force is applied and the metal is allowed deform in a straight direction. But in closed die metal is held amid the 2 halves of a die and then the force is applied to obtain a favourable outline of workpiece. Forging can also be classified on the basis of the tools used to forge them such as press forging and hammer forging.
