Abstract

L’invention concerne un élément chauffant (1) pour une buse (2) d’injection de matière plastique, adapté pour être enroulé autour de ladite buse d’injection, comprenant une première résistance chauffante (11) agencée dans une première région (R1) destinée à être située autour d’une zone avant (Z1) de la buse et une seconde résistance chauffante (12) agencée dans une seconde région (R2) destinée à être située autour d’une zone arrière (Z2) de la buse, distincte de la zone avant (Z1). L’invention concerne également une buse (2) d’injection de matière plastique, comprenant : - un corps (20) définissant un canal pour le passage d’un matériau plastique à l’état fondu, et - ledit élément chauffant (1) enroulé autour du corps (20) de telle sorte que la première région (R1) de l’élément chauffant entoure la zone avant (Z1) de la buse et que la seconde région (R2) de l’élément chauffant entoure la zone arrière (Z2) de la buse. Figure pour l’abrégé : Fig 6The invention relates to a heating element (1) for a plastic injection nozzle (2), adapted to be wound around said injection nozzle, comprising a first heating resistor (11) arranged in a first region (R1 ) intended to be located around a front zone (Z1) of the nozzle and a second heating resistor (12) arranged in a second region (R2) intended to be located around a rear zone (Z2) of the nozzle, distinct from the front zone (Z1). The invention also relates to a nozzle (2) for injecting plastic material, comprising: - a body (20) defining a channel for the passage of a plastic material in the molten state, and - said heating element (1) wrapped around the body (20) such that the first region (R1) of the heater surrounds the front area (Z1) of the nozzle and the second region (R2) of the heater surrounds the rear area ( Z2) of the nozzle.
