Abstract
The quality of the sand casting depends vastly on factors such as riser size, casting geometry, material used in casting etc. Even after taking care of these factors, shrinkage porosity is a major problem in Al and Al Alloy castings. Therefore, to avoid such defects in Aluminium castings, study of feeding mechanism for them is crucial. In the following review, factors such as solidus velocity of the metal, metal composition are effect on the feeding behaviour is study
