My company produced "Hua Wei" brand casting bentonite applied to the wet type, dry type, dry type, high-pressure type such as a different process cast steel, cast iron production. Main features are: (1), by adding small quantities, high intensity; (2), good air permeability; (3), hot wet tensile strength of high ability of anti-coarse; (4), heat is good; (5 ), a good reusability. Used as core sand binder, sand can have a good process performance, improve casting surface finish to ensure the casting quality, increase yield. In recent years, the company has developed and produced a new type of sodium bentonite and bentonite casting efficiency with superior integrated process performance, is the ideal binder for foundry sand.
