Mold or dies and methods of manufacture

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...

Beschreibung
Zusammenfassung:	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 designed 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.
