Question

Discuss the functions of core and core printing and point out its use in venting.

Answer 1

A core is a device used in casting and moulding processes to produce internal cavities and reentrant angles (an interior angle that is greater than 180°). The core is normally a disposable item that is destroyed to get it out of the piece.[1] They are most commonly used in sand casting, but are also used in die casting and injection moulding.
