Abstract

La présente invention concerne une buse destinée à une machine de moulage par injection. La buse de l'invention comprend un corps qui définit un canal de fusion. Un générateur de chaleur est relié au corps de la buse. Un corps de chauffe est également relié au corps de la buse. Le corps de chauffe est formé d'un matériau conducteur qui distribue la chaleur en provenance du générateur de chaleur le long du corps de la buse.
