Contours, cavities and passages in the casting can be possible without placing of any cores in the casting.

Contours, cavities and passages in the casting can be possible without placing of any cores in the casting. Correct Answer True

In the normal moulding, it is not possible to have any contours, cavities and passages in the casting. Cores are placed in the mould to achieve the required passages in the casting. But, a minor change in the design of casting can achieve this and also economize production cost, by eliminating cores.
