Shell moulding is a process for producing castings. It forms a mould from resin-bonded sand mixtures brought in a contact with preheated (300-500 F, 148.89-260 C) metal patterns, resulting in a firm shell with a cavity corresponding to the outline of the pattern. Shell moulding is a variation of sand moulding. The mould is formed of a thin shell of special sand. The shell is formed by coating a hot metal pattern with resin impregnated sand. The heat melts the resin which then holds the grains of sand together forming a shell.
