Abstract: Investment casting is known for its ability to produce components of excellent surface finish, dimensional accuracy and complex shapes. Inadequate surface finish, hardness and excessive shrinkage of the wax pattern often result in poor quality of the finished casting. Hence, in the present study, an attempt has been made to produce a wax blend which could offer better surface finish, minimum shrinkage and moderate hardness. Experiments were conducted with different types of waxes namely Paraffin wax, Bees wax, Montan wax and Carnabua wax, varying their proportions and stirring time. In each case, properties of wax pattern like surface finish, percentage shrinkage and hardness were determined. An attempt was made to find out the set of input parameters, which could offer a set of ideal properties of the wax blend, using Taguchi method. The set of input parameters suggested by Taguchi method was experimentally verified and found to offer the set of desired optimal properties of the wax blend pattern.
