1) Clay is rich in resources, the price is cheap.
(2) Used in the wet sand clay after proper sand treatment, most of all can be recycled.
(3) Manufacturing mold cycle is short, high efficiency.
(4) Mixed good sand can be used a long time.
(5) After sand ground real still can let a small amount of deformation without damage, is very beneficial to draft and the core.
Clay sand is sand casting industry according to the original a modelling with sand, silt content classification in the industry of clay sand quartz and the content of harmful impurities without specific request.
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.
