Abstract
L'invention concerne une buse de carotte à chauffage électrique incorporé, pour moulage par injection. Cette buse comporte un noyau intérieur allongé 14 qui présente un canal central 12 d'alimentation, un élément chauffant 16 comprenant plusieurs spires 28 qui entourent le noyau intérieur, et une enveloppe extérieure allongée 18 qui est moulée sur le noyau et sur l'élément chauffant de manière à les lier sur toute leur longueur. La chaleur de l'élément chauffant est ainsi transmise rapidement au noyau intérieur. Domaine d'application : moulage par injection.
