Hot stamping is a process in which an engraved image on a hot stamping die is heated and forced down against a part with a hot stamping foil in between them. The area on the foil which comes in contact with the die gets transferred on the part. The hot stamping foil is composed of several layers these include a polyester carrier, release layer, lacquer, metalized or pigment layer and hot melt adhesive layer. The dies used in hot stamping are made from brass and are produced by etching or machining using CNC.
