Abstract

Procédé caractérisé en ce qu'au cours d'une première étape, on réalise une ébauche (15) dans un premier moule à l'aide d'une matière d'un premier type, puis, au cours d'une seconde phase, on transfère cette ébauche (15) dans un moule de fabrication (19) que l'on remplit (18) avec une seconde matière. Suivant une variante les deux matières sont la meme, mais avec des densités différentes. La matière synthétique est le polystyrène. L'invention concerne la fabrication de pièces alvéolaires notamment destinées à la construction, au batiment, à l'emballage pour des pièces techniques destinées à l'automobile et à diverses industries.Method characterized in that during a first step, a blank (15) is produced in a first mold using a material of a first type, then, during a second phase, transfers this blank (15) into a manufacturing mold (19) which is filled (18) with a second material. According to a variant the two materials are the same, but with different densities. The synthetic material is polystyrene. The invention relates to the production of cellular parts, in particular intended for construction, building, packaging for technical parts intended for the automobile and various industries.
