SAND CASTING (Important considerations) (a)How do we make the pattern? Usually craftsmen will carve the part shape by hand and machines to the exact size. (b) Why is the pattern not exactly identical to the part shape?

Core sand is the sand that is generally used to make the core, for that reason, this sand is termed as Core Sand. Core sand consists of the mixture of core oils like resin, linseed oil, mineral oil, rich silica and the other binding materials like corn flour, dextrin, sodium silicate.
