One of the most significant advantages of sand casting is its cost-effectiveness for production runs, particularly for large and complex parts. Unlike other casting methods, sand casting does not require the creation of expensive dies, making it ideal for both prototype and high-volume production. Additionally, the sand mold can easily accommodate different metals, including aluminum, iron, and bronze, which adds to its versatility. The process is also suitable for producing large components, making it essential in industries that require heavy machinery and equipment.
