Abstract: Excessive application of investment casted precise and complex components in aerospace and automobile industries pushes developments in near net shape investment casting process. As investment casting is lost wax process, the wax pattern manufacturing is the significant part of process chain of ceramic mould development .Improvement in properties of wax pattern is needed for successful production of mould as well as casting. In present research work, approach will be made to develop pattern with the mixtures of various commercial wax and novel additives to enhance better physical and mechanical properties of wax blend as well as final pattern. In present work focus will be made on the properties tensile strength, volumetric shrinkage and surface finish as these properties directly affects the accuracy achieved for mould cavity as well as the final casting. Comparison of these properties for various wax blend combination will help for development of effective wax pattern.
