Forging is a the process of taking hot (but not melted) metal, compress it with a metal die. It is similar to a blacksmith hammering on a red-hot
piece of metal on an anvil. The forging press does this process in several steps essentially compressing the metal into a mold and pushing the molecules closer together, creating a much stronger metal than metal poured into a cast. All race cars and racing applications use forged pistons.
