Title

Abstract
(EN)
A hot runner nozzle heater is provided that includes a sleeve defining a slot extending along a length of the sleeve. A first dielectric layer is disposed over an outer surface of the sleeve, and a resistive element layer is disposed over the first dielectric layer, wherein the resistive element layer defines a resistive circuit pattern that is preferably formed by a laser trimming process. A pair of terminal leads are secured to a portion of the resistive element layer thus defining a termination area, and the termination area is positioned proximate the slot and away from the proximal end and the distal end of the sleeve. A second dielectric layer is disposed over the resistive element layer but not over the termination area, a third dielectric layer is disposed over the termination area, and a protective layer disposed over the second dielectric layer and the third dielectric layer.

L'invention porte sur un dispositif de chauffage de buses à canaux chauffants qui comprend un manchon définissant une fente s'étendant sur une longueur du manchon. Une première couche diélectrique est disposée sur une surface extérieure du manchon et une couche d'éléments résistifs est disposée sur la première couche diélectrique, la couche d'éléments résistifs définissant un tracé du circuit résistif formé de préférence par ajustage au laser. Une paire de broches de connexions est fixée sur une partie de la couche d'éléments résistifs définissant ainsi une zone de terminaison, et la zone de terminaison est positionnée à proximité de la fente et à distance de l'extrémité proximale et de l'extrémité distale du manchon. Une deuxième couche diélectrique est disposée sur la couche d'éléments résistifs mais non sur la zone de terminaison, et une couche de protection est disposée sur la deuxième couche diélectrique et sur la troisième couche diélectrique.
