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.
02/06/2020 · The role of the sand core in the casting process is to form cavities in castings of various shapes. The sand core is mainly used to form the inner hole and cavity of the casting. Fix the sand core in a specific position in the sand mold, and then pour. After the casting is completed, the sand core is wrapped in the casting (of course not completely wrapped, there must always be a mouth), and ...
