CONSTITUTION: A manufacturing method of a light-weight cam shaft comprises following steps. A cam lobe unit(110) is installed in a mold wherein the shape of a cam shaft(100) is molded. If the cam lobe unit is installed, a cavity is formed inside by coupling the molds. A half-solidified layer is created on the outer surface of the aluminum molten metal inserted into the cavity. The molten metal is injected into the cavity at low speed so that damage to the half-solidified layer is prevented.
