Abstract

This study investigates the application of software-based casting simulation for improving the design and manufacturing performance of gold jewelry casting. A cast gold ring was analyzed to evaluate molten metal flow behavior, contour fill pressure, cold shut formation, macro porosity, and Niyama factor distribution during solidification. The simulation results showed that contour fill pressure ranged from 0.138 to 1.26 MPa, indicating non-uniform mold filling behavior caused by differences in geometry, cross-sectional thickness, and thermal conditions. Thin and intricate regions exhibited lower filling pressures and rapid heat loss, increasing the probability of cold shut formation and incomplete filling defects. The Niyama factor values ranged from 0.0064 to 0.32 (°C·s)0.5·mm-1, revealing non-uniform solidification behavior throughout the casting. Low Niyama values were associated with regions susceptible to shrinkage porosity because of insufficient feeding and unfavorable thermal gradients. The study also compared the casting behavior of 18 karat and 22 karat gold alloys. The results showed that the 22 karat alloy exhibited slightly lower cold shut values due to its improved fluidity and lower flow resistance. Furthermore, increasing the casting temperature of the 22 karat alloy from 1022 °C to 1050 °C reduced cold shut formation from 0.1429 to 0.1040 and decreased macro porosity volume by 4.4%, owing to enhanced molten metal flow and improved feeding behavior during solidification. Higher temperatures also increased the Niyama factor, indicating more favorable solidification conditions and reduced shrinkage defect tendency. Overall, the findings demonstrate that casting simulation is an effective engineering tool for predicting manufacturing defects and optimizing process parameters before production. The integration of simulation into jewelry manufacturing can improve product quality, reduce material waste and production costs, and support more efficient and sustainable manufacturing systems.
