Abstract

Procédé de moulage d'un produit solidifié à partir d'un matériau moulable. Deux dispositifs à mouvement alternatif au moins (50, 52) en contact avec le matériau de moulage et comportant chacun un élément actionnable dans une chambre exercent un tenseur de contrainte avant et pendant la solidification. Ledit tenseur résulte du mouvement alternatif d'un des éléments actionnables par rapport à l'autre, selon un programme préétabli (58) qui peut être: a) même fréquence, amplitude différente et déphasés, b) même fréquence, amplitude différente et en phase, c) fréquence différente et même amplitude, et d) fréquence différente et amplitude différente. Le matériau moulable refroidit pendant son tassement pour former un produit solidifié.
