Abstract

La présente invention a pour objet un procédé d'articles métalliques. Elle est caractérisée en ce qu'on forme un mélange de particules métalliques et de particules de matières plastiques, en ce qu'on injecte ledit mélange sous pression et à température élevée dans une matrice, en ce qu'on laisse la matrice se refroidir, et en ce qu'on enlève l'article métallique de la matrice. Elle se rapporte à la joaillerie.
