  • Patent number: 8469003
    Abstract: A method of forming a fuel injector clamp utilizing powder metal techniques is provided. A powder metal charge comprising in percent by weight, 0.6-0.9 carbon, 1.5-3.9 copper, 93.2-97.9 iron with the balance other elements, is die compacted to a density of 7.0-7.1 grams per cubic centimeter pre-sintered at 1500-1600 degrees Fahrenheit to form a powder metal blank. The powder metal blank is then lubricated and re-compacted to at least 7.3 grams per cubic centimeter and sintered at 2050 degrees Fahrenheit to form a final powder metal blank. The fuel injector clamp itself is comprised of a unitary structure of powder metal having a generally cylindrical center portion, with a first wing portion extending laterally there from and a second wing portion extending laterally there from at a 180 degree angle from the first wing portion.

  • Patent number: 7931856
    Abstract: A method of forming a crankshaft bushing or similar component is provided. A compaction die is provided having an axial, generally cylindrical internal opening. An upper and a lower punch are provided with exterior surfaces corresponding to the internal opening of the compaction die. An upper core rod passes through an axial opening in the upper punch. A lower core rod passes through an axial opening in the lower punch. The upper core rod and the lower core rod each may have a generally flat external surface section. A metal powder is compacted in the compaction die by the combined action of the upper and lower punches and the upper and lower core rods.

  • Patent number: 6134786
    Abstract: Gears, particularly spur gears, are produced by powder metal techniques with minimal lead line error and eccentricity, which gears are preformed from powder metal, sintered, hardened and thereafter have their involute surfaces regenerated by a hard hob with a negative rake on the hob teeth to provide gears having aligned involute surfaces between adjacent gear teeth and, between each gear tooth and the gear center line.
