Abstract
L'invention concerne un dispositif ainsi qu'un procédé de post-traitement et de calibrage de préformes (10) sorties sous une forme instable d'un moule à injection polyvalent. L'invention propose également un refroidissement par l'air intégré dans les manchons de refroidissement (21) refroidi par l'eau pour le côté extérieur du côté d'extrémité ouvert de la préforme (10). En particulier dans le cas de types particuliers de préformes, les zones qui sont sans appui dans les manchons de refroidissement (21) peuvent être consolidées au préalable à l'extérieur, dès le début du transfert hors des formes ouvertes (8, 9) vers les manchons d'extraction ou de refroidissement, par refroidissement au moyen d'un air de refroidissement ou d'un air congelé. Cette nouvelle solution permet de garantir une qualité optimale, en particulier également du point de vue de la stabilité dimensionnelle et de la liberté de réglage de pression, par la sollicitation d'un calibrage dans les manchons de refroidissement (32) ainsi que le maniement dans la zone de post-refroidissement.
