Blow-Moulding Or Thermoforming Of Plastics Or The Like
(AREA)
Abstract
Improvements in thermo-vacuum molding machines, of the type comprising a work table with an opening surrounded by an oscillating frame, under which a thermoplastic film is passed, which is subjected to the action of an upper heater and to which it is applied underneath a mold or an object to be coated, supported on a vertically movable platform and communicated by a vacuum pump, characterized by having a peripheral elastic joint on the platform carrying the mold and making this platform of suitable dimensions for that, when ascending, said joint is applied directly against the softened thermoplastic film, thus obtaining between the platform and the film a single hermetic seal that provides greater security and requires lower closing pressure.
