The ceramic foam filter is a kind of porous material with 3-dimensional structures to remove the impurity and non-metallic inclusions during the molten metal casting. It’s been widely used in casting parts filtration like brake discs, brake drums, cylinder body and head, shaft, etc. It will efficiently perform the following characteristics,
- gas and non-metallic inclusions
- turbulence level
- surface defects
- the casting rejection rate
- mechanical properties
- surface finish
- filling capacity
- casting yield
Not at all. The filter itself will not affect the flow rate of the molten metal. The choke of the gating system plays a key role in the flow rate. It is highly recommended the filter area has to be larger than the gating system choke as suggested below.
3:1 for grey iron casting
4:1 for alumina and copper casting
5:1 even bigger for ductile iron or steel casting
