Standing cores are defined as cores that are fixed to and supported by the drag mold and that protrude upwards into the mold cavity.
Insertion of a standing core is often easier than insertion of a hanging core, particularly with very large cores. A standing core often functions as base core or bearing core (core 1 in Fig. 1), onto which other cores are assembled (Fig. 1).
