​BENTONITE FOR FOUNDRY


The molds of sand of founjdry in green are the most employees in smelting due to his versatility and his major economic efficiency. These molds need to be sufficiently stable to support the form of the piece during the emptying of the molten metal and to allow easily extract of the mold once cooled the piece. Our bentonites guarantee the suitable behavior of the mold during the different phases of the production of the piece.

 

Silmin Ibérica proposes a sodium bentonite of high purity that provides excellent characteristics to the sand recycled in the systems of I mold in green providing cohesion and plasticity to the mixture, fulfilling the requirements of the most modern systems of I mold, obtaining a high Resistance to the Compression in Green.

Bentonites range that represents, distributes and commercializes Silmin Ibérica is very stable to high temperatures being in use in foundry steel, ductile iron, and in the range of not ferreous metals, providing a lot of excellent Characteristics in I Mold:

Excellent Resistance to the Compression in Green for Unit of our added bentonite when it uses in synthetic systems of sand in green.
Exceptional in terms in speed of agglomeration.
High fluency in the sand by means of control of the compactness.

Our Bentonites wide range is based on criteria very defined depending on the final application of the product.

Bentonite for ferrous foundry
Is the the most abundant and varied in size and form of molten pieces, for what the stability of the sand that our additives provide is fundamental for the optimization of the production.

Bentonite designed to agglomerate and to assure the stability of the molds of sand in which a high thermal stability and binder should be needed. Specially indicated for smelting of steel and complex geometries.

Specific Bentonite to agglomerate and to assure the stability of the molds of sand for a wide range of metals and forms.

Bentonites with additives that agglomerate and assure the stability of the molds of sand in which a notable thermal stability and binder should be needed. Specially indicated for smelting of steel and complex geometries.

Bentonite for not ferrous foundry
Is in the habit of being more specialized than the ferrous one and therefore of major technical requirements for the molds. Again the high thermal stability is crucial in the performance of the application.

Bentonite designed to agglomerate and to assure the stability of the molds of sand in which there should be needed a very high thermal stability as well as a high refractority. Specially indicated for not ferreous smelting and refractory masses.

Bentonites with additives designed to agglomerate and to assure the stability of the molds of sand in which a high thermal stability and binder should be needed. Specially indicated for complex geometries.

Uses
Very effective when a high Resistance is needed to the Compression in  Green.
Applicable with all the types of equipments of grinding, where often they can diminish the times of mixture.
 Very recommended for the production of all the degrees of ferrous smelting that use the system of I mold with sands.

Dosing
The dosing of our bentonites changes depending on the technical requirements of the mold. The dosing ranges between 5 % and 9 %.
