Two causes of casting defects are the defects developed by solidification and by filling in mold cavity. For the solidification it is easily predicted from observing casting’s 3D geometry. For the filling, it is very difficult. since the mold is opaque the filling condition cannot be observed directly. Many casting defects such as bi-film defect, gas bubbles, loosed sand and etc., are produced by turbulent filling. The defects entrapped and floated within casting result in unreliable casting properties.
To control the liquid metal flow in mold cavity, a good and reliable runner system design becomes important. In this study a foundry is introduced to explain how they use so called Campbell’s 10 rules and Computational Fluid Dynamics (CFD) numerical software to design a good runner system. A good and reliable casting is controlled by a good runner system design. Weibull probability parameters are plotted to suggest this good runner system.
