Abstract

One result of the research on semi solid casting of iron is the development of parts having qualities that combine the superior material properties of iron with the dimensional accuracy of aluminum die-cast parts. In addition, this manufacturing method also improves the factory environment by eliminating the need for sand molds, and it utilizes the same equipment and facilities in an Al-thixo casting plant. To establish this technology, research was conducted on iron material (composition iron-carbon-silicon), molding methods using optimal billet heating speeds and copper die materials, and methods for the continuous casting of raw material billets for Fe-thixo casting. This manufacturing method was studied with an oil pump cover, in which the oil pump is directly driven by the engine crankshaft, and the same dimensional accuracy was obtained as the conventional aluminum die-cast product. Furthermore, an improvement in the volume efficiency of the oil pump was also confirmed due to the stiffness improvement and clearance reduction effects.
