Sleeves and feeders

HA Ilarduya provides a wide range of highly exothermic sleeves and feeders with excellent isolating properties.

These products help to keep metal in liquid conditions so a complete model filling is possible.

At identical module dimensions, exothermic sleeves and feeders have less internal volume than insert sleeves so they are particularly appropriate for pieces limited in space.

They considerably increase casting yields and are mainly used in nodular iron casting.

Exothermics are manufactured with the Cold Box binding process and, compared to Silicate based conventional ones, have around 30% less weight and higher mechanical and abrasion strength.

The use of these products avoids metallurgical defects in the casting contact area and surroundings and reduces moulding sand contamination due to its low fluorine content.
