Fine metallic power is mixed uniformly before it is injected into the dies of a hydraulic press. The powder is pressed into a designated shape. These formed pieces are inserted into pieces of carbon tubing, then heated slowly in a vacuum furnace. Having completed this much of the process, they are now sintered. What was once a metallic powder is now a strong metal and, adhered firmly to the carbon steel tubing, the combination is a powder sintered bushing. After they are processed through a vacuum chamber in which they are impregnated with a special lubricant, they are ready for action as self-lubricating powder sintered bushings.
