1. Design Cores are designed using computer-aided design (CAD) software to ensure precision and optimal fit with the die.

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.

- Custom Ejector Pins In some cases, the specific design of a part might necessitate custom ejector pins that accommodate unique features or shapes. These pins can be modified in length, diameter, and shape to meet the requirements dictated by the die and the final product.
