Abstract

Technologie évoluée de moulage de mousse structurée permettant d'améliorer la dispersion de l'agent gonflant dans la matrice polymère, ce qui permet d'améliorer l'état existant de la technique bien connue reposant sur une technologie de moulage de mousse structurée dont le fondement est la machine de moulage par injection du type à préplastification (en arrangement appelé « piggy-bag »). La mise en place d'un système de maintien du flux en fusion de matrice polymère, de préférence par le biais d'un accumulateur additionnel et d'une pompe à engrenages, permet de stabiliser les conditions de traitement pour disperser le gaz le gaz injecté de façon plus uniforme dans la matrice polymère. Une telle technologie permet de réduire la taille de cellule des mousses structurées, d'uniformiser la structure de cellule, d'augmenter la partie de vide (c'est-à-dire d'accentuer les économies de matériau), de réduire le tourbillon de surface et de réduire aussi le contraste de ligne de soudure.
