3 Types of Cores Used to Make Sand Castings

2013-2-13  A common example are Aluminum Sand Casting or Ductile Iron Pipes. Balanced Cores. The Balanced Core is supported by only one core print and projects into the casting cavity. Since there is only one socket, which is located on the parting line, issues can arise with misalignment and floatation if proper steps are not taken.

Sand Core Making Sand Casting Core Harrison

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. Sand cores are also widely used in die-casting, where permanent metal molds are employed.
