Investment casting is basically a metal shaping technique. It is a foundry practice by which high precision castings are manufactured. This is a specialized foundry technology and is considered a high - tech area. This process has gained popularity on the basis of the superior quality of the castings produced. Making of wax pattern is important process for investment casting. Wax pattern is made by wax injection molding machine. For making wax pattern the one important issue is temperature of wax. The temperature of wax is maintained between 60c for obtain the best result. Temperature of wax in wax injection molding machine is maintain uniform in wax tank. The band heater and cooling band are placed around the wax tank for maintain the uniform temperature of wax. The stirrer also available for rotating the wax in wax tank. So the locations of heater band, diameter of wax tank, speed of stirrer are important factor for optimum heat transfer rate in wax tank. So optimization of this parameter is done by taguchi metthod. This purpose cad software for modeling and analysis and Minitab software for DOE are used.
