Alumina Ceramic Foam Filter
Alumina Ceramic Foam Filter
Alumina 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. Alumina Ceramic Foam Filter is one of the size ,the size can be customized.
Pore Density: 10-60 PPI
Functions of ceramic foam filter
● decontaminate the melting metal liquid
● Simplified gating system
● Improve the metallurgical structure of the castings
● Reduce imparities of the castings
● Improve casting quality rate
● Reduce casting internal re-oxidation defects
● Reduce the surface defects after machining of the castings

Guide of Choosing Ceramic Foam Filter
It’s very important to choose and design filter model & filter seat correctly according to casting
types and pouring weight. The general principle is that the whole gating system should be a
system without pressure to ensure that the molten metal liquid filling mould smoothly. Ratio of the
sectional area will be the main point.
