ACTIVE bentonite mixtures

Mieszanki bentonitowo-kormixowe

ACTIVE bentonite mixtures is a modern material used in the foundry industry to make synthetic moulding compounds. It consists of carefully selected SPECJAL bentonite, charcoal dust, and a synthetic glossy carbon carrier. The use of mixtures eliminates the need to develop technology for two different materials, i.e. bentonite and coal dust. The castings are clearly of better quality – they have smooth surfaces without flaws in the form of burns, scabs, or veins. In addition, they are very accurately reproduced, thus removing the need for processing, which in turn translates into lower production costs.

ADVANTAGES OF USE:

  • facilitates the dosage of moulding compound ingredients,

  • ensures accurate surface reproduction of cast parts,

  • reduces the costs associated with casting cleaning and processing,

  • improves the quality of the castings produced,

  • improves health, safety, and fire safety conditions.

ACTIVE PLUS bentonite mixtures

Mieszanki bentonitowo-kormixowe

ACTIVE Plus bentonite mixtures are based on hybrid bentonite, glossy carbon, and a synthetic glossy carbon carrier. The new range of compounds is characterised by high strength, heat resistance and performance stability.

ADVANTAGES OF USE:

  • results in an increase in the strength of the moulding compound;

  • influences the stabilisation/growth of active clay in the compound;

  • stabilises the water requirements of the compound;

  • results in a decrease in the use of bentonite/mix of approximately 10%;

  • improves the surface quality of castings (reduction in defects).

ZGM Zębiec SA currently offers three types of bentonite mixtures with the following technical parameters:
