Abstract:
A hybrid core for manufacturing a cast component, the hybrid core including a sand core portion having an exterior shape configured to define an interior feature of the cast component. The hybrid core also includes a metal chill element embedded within the sand core portion. The metal chill element is configured to locally absorb heat energy from the cast component during cooling of the cast component and solidification thereof. The metal chill element is constructed and arranged within the sand core portion to be removed during shake out from the cast component subsequent to the solidification thereof. A system and a method for manufacturing a cast component using such a hybrid core are also envisioned.
