Abstract:
A method of molding a net-shape moldable thermally conductive article for transferring heat from a heat generating surface, comprising the steps of:providing a mold assembly capable of forming an article of a desired configuration;providing a mold cavity within said mold assembly;determining an initial location of contact on said article with said heat generating surface;forming an input gate centrally located in said mold assembly at said initial location of contact;determining the optimum heat flow path through said article;determining a termination location of said heat flow path;introducing polymer loaded with conductive filler into said mold cavity via said input gate;venting said mold assembly at said termination location;introducing polymer further including aligning said conductive filler in said polymer substantially parallel to and aligned with said heat flow path by flowing said polymer outwardly in a radiating pattern through said mold cavity; andejecting a net-shape molded article from said mold assembly.
