Abstract: PURPOSE: An MG(Magnesium) inoculation method of CGI(Compacted Graphite Iron) cast iron, and cylinder block and head made using the method are provided to skip a second inoculation process by minimizing the deviation of Mg concentration by delaying initial response to the maximum in Mg inoculation. CONSTITUTION: An MG(Magnesium) inoculation method of CGI(Compacted Graphite Iron) cast iron is as follows. A barrier divides an inner space into first and second spaces(11,12) and is installed on the floor with a given height. Mg inoculants(16) and a cover(17) are stacked from the bottom to the top on the second space of a ladle(10). The molten metal of the CGI cast iron is tapped into the first space of the ladle. If the molten metal passes through the barrier and flows into the second space, then the cover first melts, and then the Mg inoculants react.

Abstract: PURPOSE: A light-weight cam shaft and a manufacturing method thereof are provided to increase coherence without generating a gap between a cam lobe unit and a shaft unit. 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.
