Steel and iron foundries produce large castings accurately and cleanly. As the castings become more complicated, the demands on the metal increase as well. Intelligent techniques are needed on how to improve metal cleanliness so that production costs do not increase. 

Our experts developed tubular filter technology to meet these new requirements: It improves metal cleanliness and thus avoids time-consuming reworking and scrap. In addition to saving time, it reduces labor, plant training and energy costs. Our expert Ulrich Voigt explains how the tubular filter works and what other advantages it offers.
