<p>This study investigated the effects of artificial sand as a substitute for natural sand in molding applications. Various experiments were conducted to analyze the wear resistance, loss on ignition (LOI), compression strength, and surface adhesion characteristics of molding sand with different artificial sand mixing ratios. The results indicated that artificial sand, with its homogeneous particle shape and stable chemical composition, contributes to improvements in casting quality and resource efficiency. In the wear test, molding sand with artificial sand demonstrated increased wear resistance, leading to reduced particle loss and improved reusability. The LOI measurements showed a decreasing trend as artificial sand content increased, reflecting a reduction in organic and impurity content. The compression strength test results indicated that molding sands with higher artificial sand mixing ratios exhibited improved strength, particularly over extended curing times. Additionally, surface adhesion defects were noticeably reduced with increasing artificial sand content, leading to enhanced surface quality. Furthermore, increasing the artificial sand mixing ratio contributed to reductions in resin and hardener usage and a decrease in waste sand generation, improving resource efficiency. These findings suggest that artificial sand is a viable alternative to natural sand, offering benefits in both quality and sustainability for casting applications.</p>
