Abstract
A sound casting depends on the best selection and design of risers and gating system. One of the most important goals of computerizing is to have the same results for the same situation with each user in spite of his experience. Using empirical rules can not achieve that, because there are a lot of coefficients in any equation that must be chosen, they have a wide range to suit different problems. The objective of this work is to present a mathematical analysis of risers, especially side insulated risers. Formulas will be driven theoretically for calculating the riser volume, depending on exact calculation of solidification time of both casting and riser. An exact and best solution have been made for this problem which was always treated by empirical formulas. Two case studies have been made with great satisfaction.
