Abstract

Method for the vacuum molding of pieces from thermoformable sheets, characterized in that said sheets, of expanded and thermoinsulating type, especially obtained in polyvinyl chloride, polyester or polyurethane, which are properly framed and arranged between two heating apparatuses acting at the same time on both sides, preferably on the basis of infrared irradiation, so that once the second degree of uniform softening is reached, and after separation of said heating apparatuses, said sheets are applied individually in a mold in which a vacuum action is produced which determines the adaptation of the sheet on the apparent surface of the mold, adopting the sinuosities thereof, the resulting sheet being removed from the mold, after its stabilizing cooling.
