This article highlights a presentation on lost wax process metallurgy for industrial valves at a 2008 Confederation of Indian Industry (CII) National Seminar. Investment casting is another term for the lost wax process metallurgy. The origin of the investment casting process can be traced to the 1766-1122 B.C. Particular focus is given to the steps involved in wax pattern production. Heat treatment are needed for stress relieving, refining grain structure and improving strength of the castings.
