Abstract

LA INVENCION CONSISTE EN UN PROCEDIMIENTO PARA EL RELLENADO POR ASPERSION DE CUERPOS DE MATERIA SINTETICA CONTINENTES DE FLUIDOS Y EN EL DISPOSITIVO PARA LA REALIZACION DE ESTE PROCEDIMIENTO. EL PROCESO ES COMO SIGUE. POR MEDIO DE UNA TOBERA (17) SE INYECTA UN ESMALTE SINTETICO, DE POCA DENSIDAD, EN UNA CAVIDAD(7) CONSTITUIDA POR UNA ESTRUCTURA (5) DE DOS O VARIAS PIEZAS. EL PROCESO DE INYECCION SE PROLONGA HASTA QUE LA CAVIDAD SE HAYA RELLENADO TOTALMENTE. SOLO DESPUES DE QUE SE HAYA SECADO EL ESMALTE SINTETICO EN LAS PAREDES DE LA CAVIDAD (7), SE INYECTA UN FLUIDO SOMETIDO A PRESION EN EL INTERIOR DE LA CAVIDAD. ENTONCES EL INTERIOR (4) DEL CUERPO DE MATERIA SINTETICA, PRODUCIDO POR EL ESMALTE, DA LUGAR A UNA CAVIDAD (18,19) ALEDAÑA A LA CAVIDAD (7) YA MENCIONADA.
