Core (manufacturing) - Wikipedia

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. They are most commonly used in sand casting, but are also used in die casting and injection moulding.

INTRODUCTION TO FOUNDRY COATINGS - ha …

After being applied to a core or mold surface the liquid is removed by evaporation and a layer of refractory is left on the sand surface. This layer or barrier can prevent or minimize the penetration of molten metal into the sand, can reduce or prevent “burn-on” and erosion of the sand and generally improves the quality of a casting surface.

Permanent Mold Aluminum Casting Foundry

Some part designs call for the use of a steel core or sand core (also called shell core) to hold the inner dimension or hollow section of a part. Steel cores generally operate mechanically in the mold and are reusable. Sand cores or shell cores are placed in the mold before closing. This is also referred to as semi-permanent molding.

Sodium Silicate for Making Foundry Cores - Foundry Supplies

Sand is mixed with a binder to form a solid "sand core". A core must porous enough to allow gas to escape from the casting, while still blocking the molten metal. It should also be easily removed from the finished casting. Sodium Silicate is used as the binder that "glues" the sand together in cores. For example, imagine making a cannon.

Cores are made of the highest quality sand and are subject to extreme conditions during the sand casting operation. Cores must be strong and permeable; also, since the metal casting will shrink onto the core, cores must have sufficient collapsibility. Sometimes a reinforcing material will be placed in a sand casting core to enhance strength.
