The invention discloses a hot-pressing film-coating molding method which comprises the following steps: fitting a first thin film to a first mold plate; placing a layer to be hot-pressed on the firstthin film; placing an air-permeable mesh layer on the outer surface of the layer to be hot-pressed; covering the upper surface of the air-permeable mesh layer with a second thin film; sealing the edgeof the first thin film and that of the second thin film, so that the layer to be hot-pressed and the air-permeable mesh layer can be placed in a sealing bag defined by the first thin film and the second thin film; extracting air in the sealing bag; placing a second mold plate on the upper surface of the second thin film, so that the layer to be hot-pressed and the air-permeable mesh layer can beplaced between the first mold plate and the second mold plate; and placing a heating mold in a hot-pressing molding machine for hot-pressing molding, so that a workpiece molded by heating the layer tobe hot-pressed can be obtained.
