SUMMARY
In this chapter we studied that:
1. casting process principally involves pouring molted metal into mould cavity and
letting it solidify into the shape of the cavity;
2. this process can produce a wide variety of product including complex shape. Casting
processes generally are classified as expendable-mould casting, permanent-mould
casting and composite mould casting;
3. the most common expendable-mold processes are sand, shell mould, plaster mould,
ceramic mould, evaporative pattern, and investment casting;
4. common permanent-mold processes include slush casting, pressure casting, die
casting, and centrifugal casting.
