This invention provides a fast, simple, and cost-effective alternative to conventional approaches to produce molds or dies with conformal cooling channels. The main advantages of this invention include short lead time, short processing time, simple manufacturing processes, and low production cost.

This invention provides a fast, simple, and cost-effective alternative to conventional approaches to produce molds or dies with conformal cooling channels. The cooling time can be reduced significantly and the quality of the molded parts can be improved significantly. The cooling channels with any cross sectional shapes in the injection mold can be fabricated using rapid tooling and three-dimensional printing techniques. This invention has important industrial applications because injection molds with complex geometrical shapes cooling channels can be fabricated swiftly and effectively. In contrast to conventional methods regarding manufacture of injection mold with complex geometrical shapes conformal cooling channels, the main advantages of this technique include short lead time, short processing time, simple manufacturing processes, and low production cost.
