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.

An Overview Of Sand Core Making In Casting Haworth

The Isocure Process, similar to Isoset, uses a blend of dry sand mixed with a two-part resin, blown into a “corebox” to form a sand core. Core boxes are typically made of some type of metal, urethane or wood. A small amount of Amine gas is then purged through the sand and out vents in the core box.
