What is the difference between a model mold and cast?

A DIE IS a block of metal with a special shape or with a pattern cut into it that is used for shaping other pieces of metal such as coins or for making patterns

A MOULD is a container that you pour sift liquid or substance into which then becomes solid in the same shap as the container e.g. when it is cooled or cooked. A clay mould is used for casting bronze statues
