One of the primary advantages of using green sand is its ability to provide excellent mold strength. The clay content in the mixture, typically bentonite, acts as a binding agent that holds the sand grains together, creating a durable mold that can withstand the pressure exerted during the pouring of molten metal. This strength is essential for producing intricate designs and complex shapes, allowing for a higher level of detail in the finished product.
