Abstract

Pot de chauffage creux servant d'accessoire à une buse d'injection pour système de moulage par injection. Une cartouche de chauffage est enroulé en spirale sur l'extérieur du cylindre. La cartouche de chauffage contient deux conducteurs de chaleur pouvant être chauffés électriquement, qui sont électriquement séparés l'un de l'autre et qui sont situés dans différentes zones en direction longitudinale de la cartouche de chauffage. Un conducteur de chaleur est positionné de manière à chauffer la zone d'embouchure de la buse, alors que l'autre conducteur de chaleur est positionné de manière à chauffer la zone de la tige de la buse.
