    • The invention relates to a method for producing a deep-drawn film part that is at least partially imprinted, metallized and/or otherwise coated. The method comprises the following steps: making available a plain piece of film from a thermoplastic material that is at least partially imprinted, metallized and/or otherwise coated on one or both surfaces and that comprises at least one film section that corresponds to the deep-drawn part to be produced in terms of its size and imprint, metallization and/or coating; applying said piece of film in a defined orientation to a frame, only the edge sections of the piece of film lying on the frame; introducing the piece of film lying on the frame into a heating zone and heating at least the film section to a predetermined temperature; and quickly introducing the piece of film so heated into a deformation zone and subjecting it indirectly or directly to a pressure medium pressure of more than 20 bar by means of a fluid pressure medium and deforming it isotactically to the desired deep-drawn part in a period of less than 5 seconds. The method is characterized in that the heating step is carried out in such a manner that at least one side of the entire film section or of most of the part of the film section has a film surface temperature in the range of 10 to 65°C above the Vicat softening point B/50.
