Mold coatings are applied to the interior surfaces of the sand molds to improve release properties and minimize defects in the final casting. Coatings can be made from various materials, including graphite, which offers a non-stick surface, and ceramic-based coatings that provide thermal insulation and prevent sand degradation from the heat of molten metal. Choosing the right coating is vital for ensuring optimal mold performance, reducing the risk of defects such as sand burn-on, and improving the quality of the casted component.
