Abstract
PROCEDIMIENTO PARA ENCAPSULAR UNA JUNTA DE ESTANQUEIDAD DE INSERCION CON MATERIAL PLASTICO, DONDE DICHA JUNTA DE ESTANQUEIDAD DE INSERCION SE SITUA CON PRECISION EN UNA ENVOLTURA EXTERNA MOLDEADA. SE DISPONE UN ELEMENTO DE NUCLEO DE MOLDE ALARGADO QUE TIENE UNA ZONA REBAJADA SUSTANCIALMENTE EN SU ZONA INTERMEDIA. SE INYECTA UNA PRIMERA MATERIA PLASTICA FUNDIDA ALREDEDOR DEL NUCLEO EN CADA LADO DE LA ZONA REBAJADA PARA FORMAR ANILLOS DE RETENCION. LA JUNTA DE ESTANQUEIDAD DE INSERCION SE DISPONE EN LA ZONA REBAJADA ENTRE LOS ANILLOS DE RETENCION. SE INYECTA UNA SEGUNDA MATERIA PLASTICA FUNDIDA ALREDEDOR DEL ELEMENTO DE NUCLEO, DE LOS ANILLOS DE RETENCION Y DE LA JUNTA DE ESTANQUEIDAD DE INSERCION, PARA FORMAR UNA ENVOLTURA EXTERNA MOLDEADA. SE EXTRAE EL ELEMENTO DE NUCLEO PARA FORMAR UN PRODUCTO MOLDEADO DE JUNTA DE ESTANQUEIDAD DE INSERCION. LOS ANILLOS DE RETENCION SIRVEN DE ELEMENTOS DE PARED PARA EVITAR QUE LA JUNTA DE ESTANQUEIDAD DE INSERCION SE DESPLACE FUERA DE LA ZONA REBAJADA Y PENETRAR EN UN EMPLAZAMIENTO INDESEADO CUANDO SE INYECTA EL SEGUNDO MATERIAL PLASTICO FUNDIDO.
