Abstract

L'objectif de l'invention consiste à produire un procédé de stratification qui peut raccourcir le temps de chauffage par rapport aux procédés classiques lors de la stratification de pièces traitées telles que des modules de batterie solaire. Le procédé de stratification est conçu de sorte que, dans le processus de stratification, qui comprend un processus de mise sous vide et un processus de mise sous pression, le degré de vide à l'intérieur de la chambre inférieure est réduit de façon appropriée.
