  • Method for manufacturing a camshaft having added wear resistance of the lobe
    Patent number: 6484396
    Abstract: A method of manufacturing a camshaft used in an internal combustion engine. The method of manufacturing the camshaft produces a camshaft which has reduced weight and added wear resistance at a lobe of the camshaft. The camshaft is manufactured to provide increased efficiency of the internal combustion engine. The method of making the camshaft includes mixing wear resistant material with a base material and metering the mixture into a rotating die. The rotating die rotates at a predetermined speed and forces the wear resistant material to the outer surface of the lobes.
