PRODUCTS FOR FOUNDRIES

EUSKATFUND designs and manufactures a wide range of furan resins with excellent characteristics:

✓ Molds with high mechanical resistance and good thermal shock behavior.

✓ Low addition of binders.

✓ Low viscosity.

✓ Low emissions during the molding and melting phase.

✓ Very reactive systems to obtain the best performance in the most demanding Fast Loops.

✓ Slower systems to be able to work large molds that are difficult to attack, in extreme temperature conditions, both ambient and hot and highly acidic sands.

Special mention should be made of the systems free of Formaldehyde, Phenol, Nitrogen and water, which guarantee a good surface quality of the parts, without metal/mold reaction, especially in nodular iron and steel parts.

EUSKATFUND designs and manufactures a range of alkaline phenolic resins with excellent characteristics:

✓ The URSET range of resins do not contain Nitrogen or Sulfur.

✓ Particularly suitable for steel casting.

Ceramic foam filters whose main raw material is AL2O3.

AL ceramic foam filters, for application in foundries, are designed for the filtration of aluminum and aluminum alloys up to a temperature of 1,200 °C, especially for gravity casting in sand, ceramic or metal shell moulds.

✓ Foam filters help achieve lower production cost and improve the quality of the final casting.

✓ Very light.

✓ Filters can be placed in different positions within the casting system.

✓ Homogeneous porous structure with a minimum of obstructions.

✓ High pouring capacity and flow rate.

CHARACTERISTICS

✓ Working process especially suitable for the casting of steel, nodular iron and aluminum.

✓ An advantage of this process is that the binder does not contain Nitrogen or Sulfur, and the Carbon level is very low.

✓ The good thermostability of the system prevents cracks in the cores so, in many cases, it is not necessary to apply refractory coating to protect them.

EURCAST sleeves are used in casting pieces of sheet iron, spheroidal iron, steels, aluminum and copper alloys.

CHARACTERISTICS

✓ Insulating and Exothermic Sleeves.

✓ Conical, cylindrical, oval, precision insertable sleeves, casting sleeves with built-in filter.

✓ EUSKATFUND sleeves prevent defects resulting from contraction.

✓ Improves smelting performance.

✓ Significant improvement in the amount of metal poured, improving performance.

✓ Significant improvement in deburring and cleaning operations.

✓ BREAKER CORE. Composed of silica sand and chromite sand, resistant and without reaction. Flat, conical and oval breaker core.

High quality steel shot, suitable for use in any shot blasting operation.

✓ Bainitic microstructure, free of cracks, which is achieved in the tempering process due to the use of selected scrap with low Carbon, Sulfur and Phosphorus content.

✓ Low Carbon shot blasts harden, up to 46-49 HRC, in the first shot blasting cycles, due to their higher manganese content.

✓ The low Carbon and high Manganese content grits are resistant to impacts, being more tenacious and resistant to wear, improving their performance.

✓ Wear occurs due to the detachment of layers, like in an onion, in 80% of its useful life.

✓ Less amount of broken shot will cause less wear on the blades, turbine and shot blasting machine in general.
