Abstract

Process for the manufacture of molded parts by thermoforming of strips or plates of thermoplastic material brought to the deformation temperature with notable reduction of the thickness of the material in the area of the molded parts, cooling of the formed belts or plates and cutting of the molded parts from the remaining contour material, the bands or plates that are at the deformation temperature before the thermoforming being pre-cooled in predetermined areas, characterized in that the preliminary cooling is carried out on the outer areas to which they must be formed, surrounding these zones of preliminary cooling to the zones that must conform to the way of a skeleton similar to a frame.
