a core is a device used in casting and moulding processes to produce internal cavities and reentrant angles.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 injection .a third way to produce room temperature cores is by shell molding.
shell moulding, also known as shell mould casting, is an expendable mold casting process that uses a resin covered sand to form the mold.as compared to sand casting, this process has better dimensional accuracy, the process of creating a shell mold consists of six steps fine silica low tooling and equipment cost.
