Abstract

Un dispositivo per effettuare la coiniezione di almeno due materiali allo stato fluido in uno stampo comprende mezzi di canalizzazione, indipendentemente controllati in temperatura, nei quali fluiscono separatamente i materiali provenienti da uno o più impianti per l'alimentazione in pressione ed il riscaldamento dei materiali stessi.I mezzi di canalizzazione sono comunicanti con una pluralità di gruppi di coiniezione disposti in corrispondenza di punti distinti di detto stampo. In particolare vengono utilizzate delle piastre distinte munite di canalizzazioni oppure delle tubazioni distinte, indipendentemente controllate in temperatura, disposte tra i condotti di alimentazione dei materiali ad dispositivo ed i condotti per la distribuzione dei materiali ai gruppi di coiniezione (figura 1).
