However, using green sand is not without its challenges. Variations in moisture content can affect mold stability, leading to defects in the finished casting. Additionally, some foundries may encounter difficulties in achieving consistent mold strength and surface finish, necessitating close monitoring and adjustments throughout the molding process.

3) The surface of the runner rod for wax hanging should be smooth and flat to avoid excessive wax flow.

3. Design Flexibility Sand casting is compatible with a wide range of metals, including aluminum, bronze, and iron. Furthermore, it supports intricate designs and complex geometries that may be difficult to achieve with other manufacturing methods. This adaptability makes it ideal for custom projects and specialized components.
