5. Minimal Cleanup Required After the casting process, the sand used in the molds can often be reused, minimizing waste and reducing the environmental impact. Additionally, the natural properties of sand allow for clean casting, requiring less post-processing and finishing work to achieve a smooth final product.

3. Globe Valves With their complex structure, globe valves excel in throttling applications, allowing for fine control of flow rates. They are often used in power generation and chemical processing.

2. Cooling Time The cooling phase is essential for ensuring that the part solidifies adequately before ejection. Cooling time can be estimated using the thickness of the part and the thermal conductivity of the material. A common approximation for cooling time (\(t_{cool}\)) is given by

In recent years, innovations in molding technology have improved the performance of green sand. Additives that enhance binding properties and reduce moisture-related shortcomings have become more common, helping to address some of the traditional challenges associated with green sand casting. Furthermore, advancements in automated molding processes have streamlined the production cycle, making green sand an even more attractive option for both small and large scale foundries.
