The subject of research methods is to use what theyhave learned material forming technology base in the casting formingthe theory of liquid in the filling of metal, crystal, solidificationand cooling process in a series of physical and chemical changes andchanges in the castings The theoretical research and analysis. Castingon how to ensure the quality of the ingredients in the liquid alloy wascarried out research and study on the process to take the appropriatemeasures to study and explore the feasibility. According to this topic,how to apply grey (HT150)casting out the parts required the castingmolding process were discussed in detail, to use the sand casting gatingsystem design, and has made the detailed design drawings made casting,casting process chart and shape figure.
