Sand Core Making Process

Sand Core Making Process

The core makes up the internal cavities of the casting. These cores made manually can be made from silica olivine or chromite sand. But similar to molding see below process sheets are created for every core box so the operator knows exactly how to make them. The core needs to be strong enough to hold up to handling coating and pouring .
