Abstract

PROCEDIMIENTO DE INYECCION DE MATERIAS TERMOPLASTICAS, COMPOSICION DE MOLDEO PARA REALIZAR UN OBJETO DE ESTRUCTURA MULTICAPA, Y OBJETO ASI OBTENIDO, ESPECIALMENTE CUERPO DE REFLECTOR. EL PROCEDIMIENTO DE MOLDEO CONSISTE EN INYECTAR EN UN MOLDE, EN UNA SOLA OPERACION, DE UNA MEZCLA DE MATERIAS TERMOPLASTICAS QUE PRESENTAN, EN EL ESTADO FUNDIDO, VISCOSIDADES DIFERENTES. LA COMPOSICION ESTA CONSTITUIDA POR UNA MEZCLA DE MATERIAS TERMOPLASTICAS QUE, EN EL ESTADO FUNDIDO O PASTOSO, PRESENTAN VISCOSIDADES SENSIBLEMENTE DIFERENTES. EL OBJETO DE ESTRUCTURA MULTICAPA COMPRENDE UN NUCLEO INTERNO DE UN MATERIAL QUE PRESENTA UNA BUENA RESISTENCIA MECANICA Y UNA BUENA RIGIDEZ, RODEADO POR UNA PELICULA O PIEL DESTINADA A CONFERIR UN BUEN ESTADO SUPERFICIAL A ESTE OBJETO. SE APLICA ESPECIALMENTE A FAROS DE VEHICULOS AUTOMOVILES.
