Research of semi solid casting of iron

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 ferrous alloy with the dimensional accuracy of aluminum die-cast parts. Iron material composition, molding methods using optimal billet heating speeds and copper die materials and methods for the continuous casting of raw material billets were established for Fe–thixo casting. This manufacturing method was studied with an oil pump cover, and an improvement in the volume efficiency of the oil pump was confirmed due to the stiffness improvement and clearance reduction effects.
