In the mould-making step, a sand mould is formed by packing sand into the mould around the pattern. The sand mould is divided into two halves, the top half is called the "Cope", and the bottom is called the "Drag". When the pattern is removed from the cavity, it forms remains for pouring the molten metal. Mould will have other features ...
