“…The wax stage is the second most important stage affecting the casting dimensions significantly due to heavy shrinkage of wax [3,5]. Process capability study of different stages of investment casting [20] reports that wax pattern dimensions for selected wax type are uniform and consistent. Process parameters such as wax injection pressure, temperature and time from the wax stage are easily controllable by automatic wax injection machine.…”

Variation in final casting dimensions is a major challenge in the investment casting industry. Additional correction operations such as die tool reworking as well as coining operations affect foundry productivity significantly. In this paper influence of basic parameters such as wax material, mould material, number of ceramic coats and feed location on the dimensional accuracy of stainless-steel casting has been investigated. Two levels of each factor were chosen for experimental study. Taguchi approach has been used to design the experiment and to identify the optimal condition of each parameter for reduced dimensional deviation. Analysis of variance has been carried out to determine the contribution of each process parameter. The result reports that selected parameters have significant effect on the dimensional variability of investment casting. Mould material is the dominant parameter with the largest contribution followed by number of ceramic coats and wax material whereas feed location is having negligible contribution.
