Over-curing or under-curing of the shell mould, leads to the generation of sophisticated problems in the shell mould. Correct Answer True

For the curing of the shell mould, it is kept in an electric or gas fired oven. The curing of the shell should be done as per requirements only because over-curing can cause the mould to break down as the resin would burn out. And under-curing may result in blow holes in the casting or the shell may break during handling.
