According to an aspect, there is disclosed a hot runner system (100), comprising: a first surface (205) being elastically deformable; a second surface (210) forming, in cooperation with the first surface (205), a melt-leakage gap (215) being located between the first surface (205) and the second surface (210); and an active material (220) being: (i) coupled with the first surface (205), (ii) held normally stationary, (iii) configured to be operatively coupled with a signal source (225), and (iv) configured to elastically deform in response to receiving a signal from the signal source (225), upon elastic deformation of the active material (220), the first surface (205) becomes moved toward the second surface (210) such that a size (235) of the melt-leakage gap (215) becomes controlled.

Un aspect de l'invention porte sur un système de canal de coulée chauffé (100), comprenant : une première surface (205) qui est élastiquement déformable ; une seconde surface (210) formant, en coopération avec la première surface (205), un espace de fuite de masse fondue (215) qui est situé entre la première surface (205) et la seconde surface (210) ; et un matériau actif (220), qui est : (i) couplé à la première surface (205), (ii) maintenu normalement stationnaire, (iii) configuré de façon à être couplé de façon fonctionnelle à une source de signal (225), et (iv) configuré de façon à se déformer élastiquement en réponse à la réception d'un signal venant de la source de signal (205), lors de la déformation du matériau actif (220), la première surface (205) se rapprochant de la seconde surface (210) de telle sorte qu'une taille (235) de l'espace de fuite de masse fondue (215) devient commandée.
