1. for the production of the method for the deep-drawn film part that prints at least in part, metallizes and/or otherwise apply, it has following processing step at least:

  • -film spare flat, that print at least in part, metallize and/or otherwise apply on a surface or on two surfaces is provided, this film spare is made by at least a thermoplastic, and comprises at least one corresponding with the thermoformed components that will produce with regard to size and printing, metallization and/or coating film section;

    -this film spare is placed on the tenter frame with the arrangement of regulation, and wherein only the edge section of this film spare is positioned on the tenter frame;

    -film the spare that is placed on by this way on the tenter frame is introduced in the thermal treatment zone, and described at least film section is heated to given temperature therein;

    WithThen the film spare of-in this way heating is incorporated in the district that is shaped rapidly, and pressurize with the pressurized with fluid medium of pressure medium pressure greater than 20 bar therein immediately and directly, and isobaricly in time of 5 seconds be configured as required thermoformed components being shorter thanIt is characterized in that the heating of carrying out is so that at least one side of the major part of whole film section or film section has the film surface temperature within being higher than 10-65 ℃

    of scope of vicat softening temperature B/50.
