Abstract

The Philippine metals industry is envisioned at transforming the Philippines into a world-class and a reliable supplier of metal components, machineries and parts and other finished metal products. Development of other applications of spin casting could be of significant contribution to the growth of the metals industry in the Philippines. The objective of this study is to determine the optimum process parameters that will improve the quality of spin castings. Design parameters that have significant contributions in the improvement of the quality of spin casting products are identified which can serve as guidelines for researchers, designers and practitioners in the area of spin casting technology. A design of experiment optimization technique is applied to determine the optimal process parameters in the spin casting of zinc-based alloys. A polynomial regression model defining the relationship between the spin casting process parameters and the casting dimensions is used. An analysis of variance test was conducted to identify the process parameters that are statistically significant. The best results of the dimensional accuracy of the spin casting part were obtained when low values of runner length, runner diameter and disk closing pressure were used. The length of the mold runner as well as the interaction between the mold disk closing pressure and the runner length showed significant influence on the dimensional accuracy of the spin casting part. © IDOSI Publications, 2013.
