Molten metal filter screens that collect contaminants
Maxsil® HS-3000 molten metal filters are manufactured from 96% amorphous silica fiber that has been coated with a phenolic resin. They offer a pouring temperature of 3000°F/1620°C. They also offer pour rates with a 10-25% reduction as compared to unfiltered castings and castings loads up to 300kg. McAllister Mills' molten metal filters are an economical alternative to foamed ceramic filters or honeycomb ceramic filters. They are available in sheets to be cut to size or can be precut to specific dimensions.
