The key advantage of dry sand casting is the superior surface finish and dimensional accuracy it provides. The absence of moisture prevents steam from forming during the pouring of molten metal, reducing defects associated with gas entrapment. Consequently, dry sand castings often require less machining and are more precise, making them ideal for applications where tight tolerances are necessary.

Additionally, sanding helps to prepare the surface for other finishing processes, such as painting or seasoning in the case of cookware. A well-sanded surface increases the adhesion of coatings, leading to a more durable finish. Furthermore, sanding can enable the designer or artisan to achieve specific textures and patterns that may enhance the piece's visual appeal.
