Abstract

ESTE INVENTO CUENTA A UNA PERFECCIONADA TOBERA MOLDEADA DE INYECCION Y EL METODO DE FABRICARLA. LA TOBERA TIENE UN ELEMENTO CALEFACTOR ELECTRICO TOTALMENTE VACIO FUNDIDO EN COBRE CON CANALES DE ESPIRAL CORTADOS EN LA CARA EXTERNA DEL CUERPO DE LA TOBERA DE ACERO PARA HERRAMIENTAS. EL ELEMENTO CALEFACTOR TIENE UN TERMINAL FRIO EN UN EXTREMO EL CUAL PROYECTA FUERA DIRECTO A UN AGUJERO EN UN PLANCHA CABECERA, LA CUAL ES GIRABLE ANTES DE FUNDIR PARA ASEGURAR LA TOBERA, TIENE UNA LONGITUD CONSISTENTE DEL ELEMENTO CALORIFICO FUNDIDO. UN MANGUITO SE COLOCA SOBRE EL CANAL DE ESPIRAL ANTES DE FUNDIR PARA ASEGURAR EL ELEMENTO CALORIFICO EN EL CANAL ES CUBIERTO CON UN MINIMO ESPESOR DE COBRE PARA DISIPAR EL CALOR DEL ELEMENTO CALORIFICO. EL CANAL DE ESPIRAL PUEDE SER CORTADO CON UN PASO VARIABLE DE ACUERDO AL PERFIL PREDETERMINADO PARA PROPORCIONAR MAS CALOR DONDE HAY MAS PERDIDA DE CALOR.
