Castings play a vital part in all branches of engineering. The use of casting in the manufacturing industry is increased. In modern practices, a typical casting process consists of six different stages: molding, melting, alloying, pouring, solidification, and finishing. In each step, a high level of precision and control of the process is required. This work aims to critically assess the parameters that influence the casting process when an experiment using non-metallic multi-materials in sand casting process is carried out. The several sand-casting process parameters such as mold filling and solidification time etc. were analysed for the cast product, which is a truncated rectangular pyramid. The results revealed that physical, chemical, and mechanical properties alters when two non-metallic materials, such as hot melt adhesive (HMA) and paraffin wax is combined. The obtained results were analyzed by comparing them with the metallic material in the present work. This project aims to analyse and identify the various aspects of the sand-casting process of these two different non-metallic materials based on experts' available knowledge and experience.
