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.
