  • Method and device for in situ marking a workpiece in a thermal forming process
    Patent number: 11691362
    Abstract: A method for marking a workpiece (6) uses a device, wherein the workpiece (6) is formed at least partially in a thermal master or forming process, comprises a surface (10) directed towards the workpiece (6), wherein a number of individually controllable heating elements (2) is distributed behind the surface (10) for a local heating of a workpiece surface portion. Each of the heating elements (2) comprises a solid material (11) having a surface structure and a heating structure (3), wherein the surface (10) directed towards the workpiece (6) encompassing the surface structures (40) has a uniform smooth surface allowing to dark, burn or foam the surface (7) of the workpiece (6) through heat introduction.

  • Mold and device for marking work pieces
    Patent number: 11225001
    Abstract: A device for marking a work piece that is at least partially formed or reshaped through a thermal process is provided. The device includes a plurality of heating elements distributed laterally on a surface that is placed against the work piece and can be individually controlled for local heating of a work piece surface. Each of the heating elements includes a solid material with a surface structure and a heating structure. The surface structure includes at least one of a specifically or randomly varied topography. The surface structure can be at least partially heated through the heating structure.
