Complex castings can involve the use of multiple cores. Sand Core Making. Cores are produced by blowing, ramming or in heated processes, investing sand into a core box. The finished cores, which can be solid or hollow, are inserted into the mold to provide the internal cavities of the casting before the mold halves are joined.

Read More2021-3-18 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 passages inside ...
