Applicability of angular orientations of gating designs to quality of sand casting components using two-cavity mould set-up.
Rajkumar, I.; Rajini, N.; Prabhu, T. R.; Ismail, S. O.; Siengchin, S.; Mohammad, F.; Al-Lohedan, H. A. (2021-10-28)This study aimed to examine the integrity of two-cavity sand casting products in relation to the angular orientation of gating design. Two angular orientations of 60 and 45 were investigated experimentally and numerically ... -
Effects of sand and gating architecture on the performance of foot valve lever casting components used in pump industries
Rajkumar, I.; Rajini, N.; Siengchin, S.; Ismail, Sikiru O.; Mohammad, F.; Al-Lohedan, H. A.; Tawfeek, Ahmed M.; Issa, Zuheir A. (2021-11-01)This work addresses manufacture, testing and simulation of foot valve lever (FVL) for monoblock pump industry, using a cost-effective casting design process. The impact of different types of sands, such as air-set, dry and ... -
Experimental and simulation analysis on multi-gate variants in sand casting process
Rajkumar, I.; Rajini, N.; Alavudeen, A.; Ram Prabhu, T.; Ismail, S. O.; Mohammad, F.; Al-Lohedan, H. A. (2021-02-01)The present work proposes an improved multi-gate designs (MGDs) in sand casting process, using both experimental and simulation (FLOW 3D) approaches, aiming to produce defect-free component. In this regard, the variant ...
