|20120252951||THERMALLY CONDUCTIVE POLYMER COMPOSITIONS HAVING LOW THERMAL EXPANSION CHARACTERISTICS - An injection moldable, thermally conductive polymer composition that has ultra low CTE properties is provided. The composition is suitable both for substrate applications in high precision electronics assemblies as well as over molding applications in conjunction with ceramic substrates. The composition includes a base polymer matrix material loaded with thermally conductive filler, which imparts thermal conductivity to the polymer matrix while also maintaining or enhancing the dielectric properties of the base polymer. The resultant composition exhibits CTE properties in the range of between 9 ppm/° C. and 2 ppm/° C., exhibits an optical anisotropy of below 1.5, and a thermal conductivity of greater than 2W/m° K. The composition is suitable for use in over molding applications in conjunction with virtually any suitable electronics substrate material without the introduction of mechanical stresses produced by large CTE differentials.||10-04-2012|
|20100276104||SCREW DESIGN AND METHOD FOR METAL INJECTION MOLDING - A method of processing metal, metallic alloys, and metal matrix composites in a plastics injection molding machine is disclosed. The method includes the steps of providing a plastics injection molding machine having a screw. A step of removing the screw is included in the method. A step of replacing the screw with a modified screw configured and arranged for processing metals is also included. Alternatively, a step of removing the flights from the middle portion of the original screw shaft may be included.||11-04-2010|
|20080217817||SCREW DESIGN AND METHOD FOR METAL INJECTION MOLDING - A screw and method for processing metal, metallic alloys, and metal matrix composites in a plastic injection molding machine is disclosed. The screw includes shank with a screw shaft extending from the shank. The screw shaft includes a rear portion proximate to the shank, a middle portion proximate the rear portion, and a front portion proximate the middle portion. Flights extend from the rear portion of the screw shaft for advancing material through the plastic injection molding machine into the middle portion of the screw shaft. Flights may optionally be included in the front portion of the screw.||09-11-2008|
