Fluorine-free riser for more sustainability in the foundry

The use of fluorine-free risers not only reduces surface defects on the casting, but also graphite degeneration.

In addition to these aspects, however, the ecological properties are becoming increasingly important. The fluorine content of used sands and dusts plays a major role, especially in disposal and the associated classification in the various landfill classes. Increased fluorine content can thus become an undesirable cost driver.

For foundries that have a particular focus on sustainability and want to improve their environmental footprint, ASK Chemicals offers fully emission-free, inorganic mini-feeders in addition to organically bonded, fluorine-free feeders. The combination of state-of-the-art feeder systems and fluorine-free exothermic compounds is convincing: It offers effective environmental protection with better quality and lower process costs!
