Honeycomb Ceramic Filter also can be called Extruded Ceramic Filters or Molten Metal Cellular Filters, are widely used as molten metal filtration
in metallurgical and foundry industries. This product has the characters of excellent resistance to thermal shock, high strength, high porosity and specific surface area.
With its unique straight channel honeycomb designs, it can increase the specific
surface area between molten metal and ceramic filter, thereby to
improve its adsorptive and capturing tiny impurities ability, so as to get ride of non-metal impurity and gas, make the metal liquid steady, purify metal liquid. It can not only reduce casting cost, but also improve casting quality.
*Advanced casting filter manufacturer
*High strength and high thermal shock resistance
