Described are molds, dies and forming tools comprising: a) a heat exchanging body support member (12); and b) within the support member (12), a molding cavity portion (14) formed by thermal spraying metallic particles (28) to a desired configuration in the support member. Also described are methods of making a mold, die or forming tool comprising the steps of: a) providing a body support member (12) having a controlled and desined porosity which permits the enhancement of the heat transfer ability of the mold, die or forming tool; b) configuring a surface of the support member (12) to a desired cavity; and c) spraying particles (28) to the configured cavity (14) in the support member (12), thereby producing a mold, die or forming tool.
L'invention décrit des moules, des matrices ainsi que des outils à former comportant: a), un corps (12), échangeur thermique, servant de forme et, b), dans celui-ci, une cavité à moulage (14) constituée au moyen d'une pulvérisation thermique de particules métalliques (28) dans le corps susmentionné, à la configuration souhaitée. L'invention décrit également des procédés de fabrication de moule, de matrice ou d'outil à former, comportant les étapes suivantes: a) se munir d'une forme (12), d'une porosité calculée et conçue pour accroître les capacités de transfert thermique du moule, de la matrice ou de l'outil à former; b) donner à une surface de la forme (12) l'aspect en creux souhaité et c) pulvériser des particules à l'intérieur de la cavité ainsi configurée (14) dans la forme (12), ce qui permet de créer un moule, une matrice ou un outil à former.
