Abstract

LA INVENCION SE REFIERE A UNA INSTALACION DE EXTRUSION, COMPUESTA POR UNA EXTRUSORA PRINCIPAL (1) Y UNA EXTRUSORA DE INYECCION SECUNDARIA (2), CARACTERIZADA PORQUE LAS DOS EXTRUSORAS ESTAN UNIDAS A TRAVES DE UNA VALVULA DE TRES VIAS (3) Y LA EXTRUSORA PRINCIPAL (1) MUESTRA UNA PIEZA DE MEZCLADO (5) DETRAS DEL PUNTO DE DESEMBOCADURA (4) DE LA EXTRUSORA DE INYECCION ADICIONAL (2). LA INVENCION SE REFIERE ADEMAS A UN PROCEDIMIENTO PARA UN CAMBIO ACELERADO DE DIFERENTES MASAS DE MOLDEO COLOREADAS.
