摘要:
Process for the production of an at least partly printed, metallized and/or otherwise coated thermoformed film part with at least the following process steps: a flat film piece which is at least partly printed, metallized and/or otherwise coated on one or on both surface(s) and is made of at least one thermoplastic, and which includes at least one film section which corresponds to the thermoformed part to be produced with respect to size and printing, metallizing and/or coating is provided; this film piece is mounted in a defined arrangement on a frame, only the edge sections of the film piece lying on the frame; the film piece lying on the frame in this way is introduced into a heating zone, and at least the film section is heated there to a given temperature; and the film piece heated in this way is introduced rapidly into a forming zone and is charged there immediately and directly with a fluid pressure means under a pressure means pressure of greater than 20 bar and is formed isostatically to give the desired thermoformed part within a period of time of less than 5 sec. characterized in that such a heating is carried out so that at least one side of the entire film section or of the predominant part of the film section has a film surface temperature in the range of from 10 to 65° C. above the Vicat softening temperature B/50.
