What casting process allows the use of chills?

The casting process that allows the use of chills is known as sand casting. In this method, chills are placed within the sand mold to absorb heat from the molten metal, promoting solidification in specific areas and reducing the risk of defects like shrinkage or porosity. This technique enhances the mechanical properties of the final cast product by ensuring a more uniform cooling rate. Chills can be made from various materials, including metal or ceramic, and are strategically positioned based on the design of the part being cast.
