2. Mold Design The design and construction of the mold can affect how the molten metal interacts with the sand. Well-designed molds with appropriate draft angles help reduce friction, contributing to a better surface finish.

The sand casting process begins with the preparation of the mold, which consists of two halves the cope (top) and the drag (bottom). The sand used is typically a silica-based material mixed with clay and water to enhance its binding properties. Once the mold halves are formed, they are assembled, and the molten metal is poured into the cavity. After the metal cools and solidifies, the mold is broken away to reveal the finished casting. This method is highly favored for its flexibility, allowing manufacturers to produce a wide range of sizes and shapes.
