With clay and just the right amount of water as the main binder sand, made from sand directly under the wet type and after pouring. Wet mold casting has a long history and has a wide application. The strength of the green sand depends on the mixture of clay and water in a certain proportion of clay slurry. Sand is mixed good or have a certain strength, through our real sand mould, can satisfy the requirement of type and pouring. So the amount of clay in the sand and water is an important technological factors. For silt content is less than or equal to 50%. Clay sand is mainly used for cast iron and nonferrous metals casting with the addition of moulding sand and core sand, to improve the wet strength, improve the model performance.
