Abstract
A high heat-absorption casting core for manufacturing a cast component includes a core body. The core body has at least a portion thereof defined by metal powder. The metal powder is configured to absorb heat energy from the cast component during cooling of the component and solidification thereof. The core body may be additionally defined by a sand fraction in contact with the metal powder fraction. A system and a method for manufacturing a cast component using the high heat-absorption casting core are also envisioned.
