Patent ID: 11298864

Abstract:
A group of hollow modules through which the material to be extruded flows, is provided that includes at least: a rectangular heating-shaping module, in which the material undergoes a temperature increase and takes on the desired shape; and a tubular cooling-solidification module, in which the material changes from liquid to solid. A heating-reaction module is provided upstream of the heating-shaping module. The heating-reaction module includes an interchangeable hollow tube with an external heating system. The heating-shaping module includes detachable parts and includes another external heating system based on the auto-acceleration of the curing reaction and of the heat supply from said external heating system. The tubular portion between the heating-reaction module and the heating-shaping module includes a shaping coupling equipped with a through-hole. The extrusion module includes a circuit through which the polymer flows into at least two push compartments.
