Abstract
A method for manufacturing masks and masks by molding, characterized essentially because synthetic resin plates, of undetermined nature, are placed between the frame and the box of a machine, projecting on this resin the heat produced by a battery of infrared rays to determine its thermoplasticity, and, once conveniently softened, an existing inner platform is lifted in said box, in which the appropriate molds of suitable material have previously been placed, until contacting the plate of the thermoplastic material, taking place at that moment the vacuum of the box by means of a valve or rigid tube that communicates to the same with a cylinder, in which previously the vacuum has been produced; when the air is dislodged from the box, the plate of the thermofuging material yields and adapts perfectly to the reliefs of the corresponding mold, with which the masks are formed, cooling them immediately.
