Ceramic foam filter is a kind of effective molten metal filter. It’s 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.

Functions 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
