The sand casting process begins with the design and creation of a pattern, which is a replica of the final product. The pattern is typically made from a material such as wood, plastic, or metal and is used to create a cavity in the sand mixture. The most common type of sand used is silica sand, chosen for its ability to withstand high temperatures and its desirable mold characteristics. The sand is mixed with a binding agent, usually clay, to ensure it holds its shape when packed around the pattern.

Moreover, die casting offers exceptional dimensional stability, which is crucial for parts that need to fit precisely with mating components. When creating intricate designs, manufacturers can achieve thin wall sections and complex geometries that would be challenging with other manufacturing methods. The strength-to-weight ratio of die-cast materials also makes these parts ideal for applications where weight savings are essential, such as in the automotive and aerospace sectors.

Casting sand, also known as foundry sand, is a mixture primarily composed of silica (SiO2) along with other components like clay, water, and chemical additives. These elements work together to form a mold that can withstand the high temperatures of molten aluminum while providing the necessary thermal resilience and structural stability.
