Abstract


In the mold design scope, the quality of the casting product is important to fulfill customer satisfaction. Effective casting of pressure-tight casting need close conformance to the principle of sound casting product design. Guidelines concerning corners, ribs, fillets and chamfer should be follow carefully to avoid casting defect on the product. In this project, describes about to optimize design and simulation of vertical and horizontal position of cavity design by using ANYCASTING and FLEXPRO software thermal analysis at the certain area of the mold cavity. The result shows, vertical mold design produced less defects than the horizontal mold design and filling time for vertical mold design is 1.6546 seconds and complete solidification time is 504.7066 seconds. For the partial tracing analysis, it shows   double turbulence occurs on the horizontal cavity and single turbulence on horizontal cavity.
