Title
(EN) MODULAR INJECTION NOZZLE HAVING A THERMAL BARRIER
(FR) AJUTAGE D'INJECTION MODULAIRE POSSEDANT UNE BARRIERE THERMIQUE
Abstract
(EN)
An injection molding apparatus having a nozzle which includes a first nozzle body segment, a second nozzle body segment, and a thermal barrier coupled between the nozzle body segments. The first nozzle body segment, the thermal barrier, and the second nozzle body segment define a melt channel through the nozzle for delivering a melt stream from a manifold channel of a manifold to a mold cavity. The thermal barrier substantially limits the heat flow from one nozzle body segment to the other, to thereby control the heat distribution along the melt channel.
(FR)
Dispositif de moulage par injection possédant un ajutage comprenant un premier segment d'ajutage, un deuxième segment d'ajutage et un barrière thermique placée entre lesdits segments. Le premier segment d'ajutage, la barrière thermique et le deuxième segment d'ajutage définissent un passage de fusion à travers l'ajutage servant à alimenter une cavité de moulage en un écoulement en fusion provenant d'un conduit de collecteur. La barrière thermique limite pratiquement le flux thermique entre les segments d'ajutage, ce qui permet de réguler la distribution de chaleur le long du passage de fusion.
