The sand casting process begins with the creation of a pattern, which is a replica of the object to be cast. The pattern is typically made from metal, wood, or plastic and is slightly larger than the finished product to account for shrinkage during the cooling process. Once the pattern is ready, a two-part mold is formed by packing sand mixed with a bonding agent around the pattern. The sand needs to be tightly packed to ensure it can withstand the molten metal's weight and temperature.
