Foam ceramic filter, Honeycomb ceramic filter
SiC foam ceramic filter
Since the internal structure of the foam filter is a three-dimensional honeycomb type, the size and shape are irregular; it can absorb particles and remove inclusions in the molten iron, and make metal filling steady in mould. It can also reduce air flow and casting impact in mould,and significantly decrease casting defects such as pin hole and sand hole, etc. to improve casting quality and manufacturing yield.

Honeycomb ceramic filter
The size and shape of the straight hole ceramic filter are stable which is made of mullite refractory materi-als, the main chemical composition is similar to that of sundries in molten iron, so it has a strong adhesive force to the impurities in molten iron, especially the tiny sundry goods in the ductile iron molten iron is adsorbed on the surface of straight hole extruded ceramic filter. The adsorption capacity of foam filter to tiny sundries is not comparable with the honeycomb ceramic filter.
