Below is a list of Cold Forming manufacturers from Antioch, Illinois. Cold forming is a metal working process by which small, simple parts are produced. Unlike traditional metalworking processes, cold forming does not use heat. Instead, high pressure and/or impact is applied to the metal blank in order to shape it. To be effective, this force must exceed the material's elastic limit in order to change its structure. However, the metal is typically not forced past its tensile strength as that would result in fracturing or cracking.
