Why are casting filters used during foundry production

In casting production, the rejection rate of castings is 50 to 60% due to casting problems such as non-metallic inclusions. 

The inclusions do not only reduce mechanical properties of the casting, but also has a great influence on processability and appearance. 

The use of casting filters has become an important auxiliary material for purification of liquid casting alloys and reducing or filtering various non-metallic inclusions, then good quality castings can be obtained.
