Bentonite for Foundry

Bentonite is used as a bonding material in the preparation of moulding sand for the production of iron, steel and non-ferrous casting. The unique properties of bentonite yield green sand moulds with good flowability, compactability and thermal stability for the production of high quality castings.

Quartz sand  forms the structural framework of the mold thanks to bentonite, which binds the sand particles together, giving the mold strength.

The main advantage of bentonite is the ability to restore its properties after additional hydration. This allows you to reuse the moldable mixture after pouring molds with metal and knocking out castings.

Repeated use of the molding mixture with bentonite significantly reduces the cost of waste transported to dumps and their disposal.
