Cores are made by removing moisture with heat. No reactive chemicals are used, so the core making area is safe for the workers. The binder is biodegradable, and there are no hazardous chemicals or wastes to deal with. Cores made with GMBOND are dimensionally stable, produce a smooth casting surface, and are easily removed from aluminum castings.

Cores create flexibility in sand casting. The ability to make and place sand cores is a vital part of the casting process. In some instances, the core is necessary for the utility of the final part: tubes, engines, and other mechanical devices often need to be hollow to work. For decorative items, cores can also cut down on the total cost of metal.

to allow the sand core to be withdrawn from the box after the core has cured. Fillets Sharp, internal corners on a casting design should be avoided whenever pos-sible. The small volume of mold media located in a casting's internal corner quickly becomes superheated and limits the casting's ability to transfer heat at this location.

Casting Cores. A core is a preformed, bonded, sand insert placed into the mold to shape the interior of a casting or a part of the casting that cannot be shaped by the pattern. Cores are frequently used to create hollow sections or cavities in a casting. A good casting core is a critical component for a quality casting at Francis Manufacturing Company.

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.. For example, cores define multiple .

Yellow—Indicates this surface to be machined on final casting. Black—Indicates the surface needs a core, and where the core's position might lie. Clear varnish or unpainted—Indicates parting line or join on the casting. Storing and reusing patterns. A pattern can have a long life in a foundry, used to make hundreds or thousands of castings.
