Abstract
A casting die includes a main cavity, a first reservoir and a first vent. The main cavity has a first interior volume for receiving a first molten volume of metal. The first reservoir is in serial fluid communication with the main cavity for storing a first molten backfill volume of metal to accommodate solidification shrinkage in the main cavity. The first vent is in serial fluid communication with the first reservoir.
