Abstract: The investment casting process is gaining prominence, especially in the production of complex, high-quality components with near-net shapes, due to its exceptional versatility and adaptability. A major challenge in this process, however, is the shrinkage of wax patterns, which substantially affects the quality of the final product. This shrinkage is influenced by multiple variables, including the wax composition, mold and injection temperatures, pressure, and duration of injection. In this study, the Mold flow simulation software was utilized to evaluate volumetric shrinkage. This simulation presents a promising approach to significantly enhance the dimensional accuracy of wax patterns in investment casting.
