Abstract

L’invention concerne un réchauffeur (16) de résine d'injection comportant un circuit interne de résine (28) agencé au contact d’au moins un élément chauffant (60, 62), ledit circuit de résine (28) étant délimité entre une gouttière (30), qui est formée dans une première face (32) d’une première plaque (34), et une deuxième plaque (36) dont une seconde face (38) est appliquée sur ladite première face (32) pour fermer ladite gouttière (30), caractérisé en ce qu’il comporte une membrane souple (44) qui est interposée entre lesdites première et seconde faces (32, 38), qui délimite avec la seconde face (38) un volume étanche (46) et qui recouvre au moins une partie de la gouttière (30), et en ce que le réchauffeur (16) comprend un port d’alimentation (47) en gaz sous pression dudit volume (46) permettant de déformer la membrane (30) à l’intérieur de la gouttière (30). Figure pour l'abrégé : figure 5.
