Abstract

Improvements applicable to the moulding of polyester and the like in which there is a mould and countermould associated with the movable plate and bed of a press for the purposes of determining between both a joint moulding chamber in which the sheet polyester will be deposited in order to be adapted at pressure and temperature in the mould cavities, being characterized in that the moulding chamber is closed hermetically with respect to the outside during the working cycle and is in communication with an external vacuum pump for generating a relative vacuum of the moulding chamber prior to the compression of the polyester mass, including the arrangement of leaktight means on the faces where mould and countermould coincide. These improvements prevent filling defects in narrow and deep areas of the moulds.
