Round-hole filters
One of the main causes of high rejection rates are inclusions in cast parts. But this is one area where quality standards can easily be raised. Rely on ceramic filters from HOFMANN CERAMIC, which have been tried and tested many millions of times in practice.
We operate our own highly developed in-house tool manufacturing facilities and maintain excellent links with the scientific community. As a result, as well as creating first-class series products, we are also able to customize products to your own specific requirements.
Filtered cast parts are not only much stronger, but also reduce wear and tear on processing tools by up to 15 percent.
Our pressed, ceramic round-hole filters are produced using an in-house dry-pressing process that is unique worldwide. What's more, they are the only such filters on the market that are stamped "Made in Germany". Precisely calibrated flow rates ensure your casting processes are homogeneous, and the filters have already demonstrated their dimensional stability and quality for large castings weighing up to 50 t.
