We have a wide variety of conventional & CNC machining equipment for all complex machining needs. Hot stamping is a process where a heated engraved image or hot stamping die is forced down against the material to be printed, with the marking foil sandwiched in-between. Where the raised area of the die strikes the material, foil or ink is transferred. The stainless steel passivation process removes free iron contamination left behind on the surface of the stainless steel, which results in premature corrosion. In addition, the passivation process facilitates the formation of a thin, transparent, oxide film that protects the stainless steel from selective oxidation (corrosion).
