A thermoplastic sheet is heated just above a shaped mould. When air is evacuated from below the mould it creates a vacuum and the heated thermoplastic is sucked over the mould to take its form. Air is then blown back up through the mould to dislodge the moulded plastic. Note that vacuum formed sheets need a lot of trimming away of excess material after forming.
