Abstract : Casting is an especially flexible process that can be utilized by foundries for production on a large scale. Due to their importance as a source of castings, foundries now play a significant role in the industrial sector. The production of excellent castings at the lowest possible cost is the ultimate aim of the manufacturing sector. Undesirable imperfections in the metal casting process are known as defects. A number of issues that are process-related are the reason for the defects. A few defects can be tolerated while others can be fixed, or they can even be eliminated with good moulding technique. These imperfections develop as a result of a few production cycle processes that are not effectively monitored. Sand casting company efficiency is negatively affected by poor casting. For strong castings, the challenging casting defect conditions must be identified and reduced. By reducing casting defects throughout manufacturing, the foundry sector can improve its level of quality. The primary objectives of this study are to identify the significant sand casting defects and analyze the preventative measures to reduce the defects. In this work, efforts are undertaken to identify technically feasible remedies for minimizing a variety of casting weaknesses and improving casting quality.
