Prototype sand casting is a type of sand casting that focuses specifically on creating prototypes or models of metal parts. The process begins with the preparation of a sand mold, which is made from a mixture of sand, clay, and water. The sand is packed around a pattern, usually made of metal or plastic, to create a hollow cavity in the desired shape of the final product. Once the mold is formed, it is removed from the pattern, and molten metal is poured into the cavity. After the metal cools and solidifies, the mold is broken apart to retrieve the cast part.

3. Precision The process allows for the production of intricate and complex designs. This is especially useful in industries that require detailed components, such as automotive and aerospace.
