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.

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.
