Hot Stamping is the process of pressing a custom-made heated die into a part. Hot Stamping is typically performed on softer non-metallic materials such wood, leather, cork, and rubber. When other forms of Impression Marking are attempted with softer materials, the mark will “release” or not stay in place. The heat from a Hot Stamping procedure, in conjunction with the pressure and dwell time, will yield a deep, lasting mark.
