NATI Ceramic foam filter is a kind of effective molten metal filter. It is three dimensional connected mesh structure and high porosity has many advantages, for example, large surface area of slags  collection, large inner surface area of filtering, small flow resistance, good filtering effect, etc.

Function of Ceramic Foam Filter

*Decontaminate the molten metal liquid

*Simplified gating system

*Improve the metallurgical structure of the castings

*Reduce slag inclusions of the castings

*Increase the casting quality rate

*Reduce casting internal re-oxidation defects

*Reduce the surface defects after machining of the castings
