Abstract
LA INVENCION HACE REFERENCIA A UN PROCESO Y UN UTIL PARA EL PRENSADO DE EXTRUSION PARA LA FABRICACION DE UN TUBO (1) CILINDRICO, METALICO O DE CERAMICA, CON UNO O VARIOS TALADROS LONGITUDINALES RETORCIDOS SITUADOS EN EL INTERIOR (2). MEDIANTE PRENSADO DE EXTRUSION, EL MOLDEADO, PLASTIFICADO Y PULVERIZADO MATERIAL DE PARTIDA SERA PRENSADO MEDIANTE UN VOLUMEN CONFORMADO POR UNA TOBERA (4) Y UN MACHO (11). EN EL EXTREMO DEL MACHO (11) ANTES DEL ESPACIO INTERIOR (8) DE LA TOBERA (4) ESTAN FIADOS UNA O VARIAS CLAVIJAS MEDIAS RETORADAS (7) HECHAS DE MATERIAL RIGIDO PARA LA FORMACION DE TALADROS LONGITUDINALES (2). SE CONSEGUIRA QUE LA POSICION DE LOS RETORADOS TALADROS LONGITUDINALES (2) SEA MUY IGUAL DENTRO DEL TUBO CILINDRICO EXTREMADAMENTE SIMETRICO Y ENTRE LOS DIFERENTES TUBOS DE FABRICACION AISLADA.
