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.
