Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working), warm forging, or hot forging (a type of hot working). For the latter two, the metal is heated, usually in a forge. Today, forging is a major worldwide industry.

What are examples of forging?
Forged has traditionally been the mark of quality in hand tools and hardware. Pliers, hammers, sledges, wrenches and garden tools, as well as wire-rope clips, sockets, hooks, turnbuckles and eye bolts are common examples. Surgical and dental instruments are also often forged.
What is the upset forging?
Upset forging involves locally heating a metal bar and then, while holding it firmly with special tooling, applying pressure to the end of the bar in the direction of its axis to deform it. The process allows the production of long parts with a forged end.
