Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA FUNDICION DE INYECCION DE OBJETOS DE PLASTICO, DONDE EL PLASTICO SE PLASTIFICA EN UN AGREGADO DE INYECCION ASI COMO PLASTIFICADOR, Y SE INYECTA LA COLADA DE PLASTICO EN LA CAVIDAD DE UNA HERRAMIENTA DE FUNDICION DE INYECCION. DE ACUERDO CON LA INVENCION SE UTILIZA EL PLASTICO ANTES DE LA INYECCION EN LA CAVIDAD (3) CON LACA; SIN QUE SEA NECESARIO NINGUN RECUBRIMIENTO DEL MATERIAL DE PLASTICO CON LACA, SINO DE FORMA ESPECIAL UNA MEZCLA DE LA LACA CON EL PLASTICO. LA MEZCLA DEL PLASTICO Y LA LACA PUEDE CONSEGUIRSE ANTES DEL PROCESO DE PLASTIFICACION. LA LACA ES SOLIDA O LIQUIDA. EL PLASTICO PUEDE SER AÑADIDO CON ELLO ESPECIALMENTE ANTES DE LA FUNDICION Y MEZCLARSE CON EL GRANULADO DE PLASTICO ANTES DE LA AFLUENCIA EN EL AGREGADO (1,2) DE FUNDICION DE INYECCION Y DE PLASTIFICACION EN LA RELACION DE DOSIFICACION DESEADA. CON PREFERENCIA SE UTILIZA UN CONCENTRADO DE LACA. LA MEZCLA DE LA LACA PLASTIFICADA Y DE LA COLADA DE PLASTICO PUEDE CONSEGUIRSE SEGUN UN PROCESO DE PLASTIFICACION SEPARADA DE LA LACA EN UNA UNIDAD (5,6) PLASTIFICADORA.
