Patent

CA 2234365

Processes for providing enhanced thermal properties of tooling, particularly metal and metal/ceramic molds (8), made by solid free form fabrication techniques, such as the three-dimensional printing process, and the tooling made by these processes are disclosed. The methods of enhancing thermal properties include incorporating integral contour coolant channels (6) into the mold, adding surface textures to the coolant channels, creating high thermal conductivity paths between the surfaces and the coolant channels, and creating low thermal inertia regions in the mold.

L'invention se rapporte à des procédés visant à améliorer les propriétés thermiques d'outillage, notamment de moules en métal et métal/céramique (8) obtenus selon des techniques de fabrication de formage libre de solides telles qu'un procédé d'impression tridimensionnel, ainsi qu'à l'outillage fabriqué selon ces procédés. Les procédés d'amélioration des propriétés thermiques consistent à intégrer dans le moule des canaux (6) de refroidissement des contours, ajouter des textures de surface aux canaux de refroidissement, créer des voies de haute conductivité thermique entre les surfaces et les canaux de refroidissement, et créer dans le moule des régions de faible inertie thermique.
