Ceramic Honeycomb Filter (also called Extruded Ceramic Filter) apply to metal liquid filtration, has the function as:
1. eliminate big oxide mechanically by it’s small hole
2. commutate turbulent laminar flow
3. absorb impurities by it’s eyelets
4. improve casting/foundry products density, intensity and toughness, enhance productivity rate
