Bentonite

Bentonite for founding industry
Bentonite serves as an economical bonding material in the molding processes associated with the metal casting industry. Bentonite, when mixed with foundry molding sands, forms a pliable bond with the sand granules. Impressions are formed into the face of the bentonite/sand mixtures. Molten metal is pored into the impressions at temperatures exceeding 2,800 F. The unique bonding characteristics of bentonite insures the durability of the mold during these high temperatures. once the process is complete, the bentonite/sand mold can then be broken away from the casting face and reused.
For over 10 years foundrymen have used our calcium bentonite as the binder of choice for making greensand molds for metal castings. Our Bentonite is a unique blend of high quality bentonite that has been specifically designed to have properties similar to those found in custom blends of sodium and calcium bentonites. The rapid rate of water absorption and low water requirement for activation often result in shorter mulling times for sands bound with our Foundry Grade Bentonite. These sands exhibit high green, dry and hot compression strengths with low compactability, good permeability and a high level of durability. This makes our foundry Grade Bentonite an excellent binder choice for all types of greensand metal casting.
