In practice, ceramic foam filters are generally used in aluminium sand and die casting processes in order
to decrease number of defects. Efficiency of filters depend on the pore size. Ardekhani and Raiszadeh [1] claim
that 30 ppi filters can eliminate almost all of bifilms from molten aluminium but filters will decrease cleanliness
of molten metal because of creating new surfaces. Bozchaloei et al. [2] indicate that it is important that it is
important where the filter is placed in mould cavity. Also, efficiency of filtration is more than 65% to increase
mechanical properties of casting parts [1, 3].
