Forging is a machining process. A forging is an object made of metal that is subjected to pressure and shaped into a desired shape or suitable compressive force through plastic deformation. This power is typically achieved through the use of a hammer or pressure. The forging process creates a refined particle structure and improves the physical properties of the metal.
The advantages of forgings include stretchable length and shrinkable cross-section; Shrinkable length, extendable cross-section; Adjustable length, adjustable cross-section. The types of forgings include: free forging/hand forging, hot forging/precision forging, top forging, roll forging, and die forging.
