Bentonite for Foundry

“Huawei” bentonite used for Chemical, Coatings, Rubber pesticide, Fertilizer, Fodder, Medicine, Cosmetics, Paper making, Purifying water, Animal feed, Food grade for humas, Moisture absorption of water and others.

   "Hua Wei" series casting bentonite is be used of green sand mold, drying mold,etc. for casting production. Be suitable for wet type, dry type, dry type, high pressure molding processes for various steel, cast iron production . Main features are as follows: 

1.Adding less, high strength. 

2.Good air permeability. 

3.High wet-heat tensile strength , high resisting sand inclusion ability. 

4.High temperature resistance. 

5 Good reusability. 

    As a core sand binder, make molding sand has good process performance, to improve casting surface finish, to ensure the quality of castings and improve yield.

    In recent years, our company has developed and produced a new type of sodium bentonite and synergistic casting bentonite, with more excellent process performance, is the best right binder for foundry sand.
