Green sand is made up of several key components. The primary ingredient is silica sand, which provides the mold with its structure. The sand is typically combined with a certain percentage of clay, usually sodium bentonite, which serves as a bonding agent, helping to hold the sand grains together. Water is added to this mixture, activating the clay and making it pliable. The proportions of these materials can vary depending on the specific requirements of the casting application, but a typical formulation consists of about 90% sand, 10% clay, and 2-5% water.

Additionally, manufacturers should conduct thorough testing during implementation. Process parameters such as coolant temperature, pressure, and flow rates need to be optimized for the specific casting process. This testing phase is essential to fine-tune the system and ensure that the desired cooling effects are achieved without introducing new defects.
