CA 2567538

Coinjection molding system control apparatus and method preferably includes flow control structure and/or steps configured to reduce pressure on a second melt, preferably causing a relatively small portion of a first melt to flow from a distal portion of a first melt channel in the coinjection nozzle into a distal end of a second melt channel in the coinjection nozzle. This prevents substantial amounts of the second melt from being dragged into the mold cavity when the next shot of the first melt is injected.

Cette invention se rapporte à un appareil et à un procédé de commande pour système de moulage par co-injection, qui utilisent de préférence une structure et/ou des étapes de commande d'écoulement conçues pour réduire la pression sur un second bain de fusion, de façon à amener de préférence une partie relativement petite du premier bain de fusion à s'écouler depuis une partie distale du premier conduit de bain de fusion dans la buse de co-injection jusqu'à une extrémité distale d'un second conduit de bain de fusion dans la buse de co-injection. On empêche ainsi que des quantités importantes du second bain de fusion ne soient attirées dans la cavité du moule, lors de l'injection de la charge d'injection suivante du premier bain de fusion.
