Cold stamping is a metalworking process that uses a cold or unheated hammer to imprint a pattern on the surface of a workpiece. In other words, it is a type of non-heat-treatable surface finishing process in which the properties of the metal are changed by applying pressure to the surface of the material and leaving an image.
