The casting bentonite produced by Chunyuan Bentonite Processing Plant in Heishan County is suitable for the production of cast steel and cast iron using different processes such as wet mold, dry mold, surface dry mold, and high-pressure mold.

The main features are:

(1) Low dosage and high strength;

(2) Good breathability;

(3) High thermal wet tensile strength and strong resistance to sand inclusion;

(4) Good high-temperature resistance;

(5) Good reusability. When used as a core sand adhesive, the sand can have good process performance, improve the surface smoothness of castings, ensure the quality of castings, and improve the yield.

In recent years, our company has developed and produced new types of sodium based bentonite and casting efficiency enhancing bentonite, which have better comprehensive process performance and are ideal adhesives for molding sand casting.
