Design of gating system is vital in any molding or casting processes, in order to get defect free components. As far as the casting of pump casing is concerned, finding the “Hot Spot” is very important, as most of the casting defects occur at the “Hot spot”. “Hot Spot” is the part of casting that gets solidified last. The “Hot Spot” usually occurs at the thickest cross section of the casting. By simulation, the most appropriate location is selected for incorporating the Gating system (gate, sprue, runner and riser) so that the “Hot spot” will be shifted to the Riser and hence we get defect free components. This task is achieved through software known as WINCAST, which is exclusively used for casting process.
