Abstract
APARATO Y PROCEDIMIENTO PARA LA FABRICACION DE ARTICULOS DE MATERIAL PLASTICO. EL APARATO (10) COMPRENDE MODULOS DE INYECCION CONJUNTA (12) ALIMENTADOS CON MATERIALES POLIMEROS DIFERENTES, A PRESION INTERMEDIA, POR PLASTIFICADORES COMUNES (14, 18). CADA MODULO TIENE UN CONJUNTO DE TOBERAS DE INYECCION CONJUNTA (70) ALIMENTADAS CON POLIMERO A PRESION POR MEDIO DE UN INYECTOR (208). CADA POLIMERO ES INYECTADO POR EL INYECTADOR DIRECTAMENTE AL INTERIOR DE LA TOBERA CORRESPONDIENTE Y ESTA CONTROLADO SOLAMENTE POR EL FUNCIONAMIENTO DEL INYECTOR, Y SIN EL EMPLEO DE VALVULA DE REGULACION ALGUNA ENTRE EL INYECTOR Y LA TOBERA. LOS MICROPROCESADORES DE LOS MODULOS SE CONTROLAN MEDIANTE UN PROCESADOR PRINCIPAL, QUE ORGANIZA LAS OPERACIONES DEL APARATO. LA INVENCION TIENE APLICACION, POR EJEMPLO, EN LA FABRICACION DE BOTELLAS.
