Abstract
Tool having a molding surface is formed from a flowable material (e.g., powder material) wherein the shape of molding surface is formed from a molding process using a master pattern having a surface with a shape substantially the same as the shape of the molding surface to be formed. The tool has at least one thermal control element located within it and spaced from the molding surface where a component used in forming the thermal control element is located within the flowable material prior to solidifying the material. The powder material is preferably a mixture of metals. The thermal control elements include fluid flow paths, heating elements, temperature sensors, and the like.
