Abstract
PARA PRODUCIR MEDIANTE UN METODO DE MOLDEO POR INYECCION UNA PIEZA DE GRAN TAMAÑO Y BASTANTE PESADA (1) DE UN MATERIAL DE PLASTICO, EL METODO MEJORADO DE LA PRESENTE INVENCION CONSISTE EN CREAR UNAS ZONAS LOCALIZADAS EN LAS QUE LA CODUCTANCIA DE LA PIEZA (1) SEA MAYOR EN UNAS IMPRESIONES SUPERFICIALES (10) QUE SE CORRESPONDEN CON UNOS EYECTORES FORMADOS EN EL MOLDE PARA DESMOLDEAR LA MISMA PIEZA UNA VEZ HA SIDO MOLDEADA. EN UNA REALIZACION PREFERENTE DE LA INVENCION, LA SUPERFICIE EXTERIOR DE LA PIEZA (1) TIENE, EN CORRESPONDENCIA CON LAS IMPRESIONES SUPERFICIALES (10), UNAS AGRUPACIONES DE ALVEOLOS DE FONDO CERRADO (13) FORMADOS POR UNAS REJILLAS DE MINISALIENTES (11) (112) DISPUESTAS EN PERPENDICULAR ENTRE SI. EL GROSOR DE LA PIEZA CAMBIA DE UN VALOR MAXIMO (S1) EN LA PERIFERIA DELA CAVIDAD A UN VALOR MINIMO (S ) CORRESPONDIENTE AL FONDO DE UNA PARTE SUSTANCIAL DE DICHOS ALVEOLOS (13).
