    摘要: A structural frame (12) for dissipating heat from an electronic device (10) is provided. The structural frame (12), to which an electronic circuit board (14) containing a heat generating electronic component (16) is mounted, is injection molded from a thermally conductive, net-shape moldable polymer composition. The electronic component (16) that is within the device (10) is in thermal communication with the structural frame (12), so that the heat generated within the device (10) is transferred to the frame (14) and dissipated from the heat-generating device (10). An outer case (22) may be mounted to the frame (12) to finish the device (10) or the frame (12) may serve as all or a part of the outer device case (22) as well. In addition, the structural frame (12) has characteristics that may be engineered and used to shield the device (10) from electromagnetic interference.

    摘要: A screw (10) and method for processing metal, metallic alloys, and metal matrix composites in a plastic injection molding machine (24) is disclosed. The screw (10) includes shank (12) with a screw shaft (14) extending therefrom. The screw shaft (14) includes a rear portion (20) proximate to the shank (12), a middle portion proximate (18) the rear portion (20), and a front portion (16) proximate the middle portion (18). Flights (22) extend from the rear portion (20) of the screw shaft (14) for advancing material (K) through the plastic injection molding machine (24) into the middle portion (18) of the screw shaft (14). Flights (22) may optionally be included in the front portion (16) of the screw (10).

    摘要: A method of molding a reinforced article (100) for optimizing heat transfer, electrical conductivity and/or structural integrity is provided. A mold assembly is first provided which is capable of forming an article (100) of a desired configuration, which may include a base (112) and upstanding fins (114). The desired positioning of the filler within the molded article (100) is determined according to the thermal, electrical or structural needs of the article (100). An input gate (116) and output gate vent (118) is formed in the mold assembly to insure positioning of the filler as desired. Polymer, loaded with reinforced filler, is introduced into the mold assembly via the input gate (116). Polymer is positioned in the mold assembly with the reinforcing filler being substantially parallel and aligned with the flow path. A bottom surface (120) of base (112) is provided with flush thermal communication with a heat generating device which may be positioned in the area designated (122).
