Ceramic
Honeycomb Filters
for Metal Filtration
Ceramic honeycomb filters remove non-metal impurities and gas, purifying and making the metal liquid steady. As a result, they reduce the casting costs and improve the quality of the product, making it the superior product to other options like 3D-printed and foam filters.

Ceramic Honeycomb & Holy Filters
CERAMIC HONEYCOMB FILTERS
Ceramic honeycomb filters are the best option if the company needs superior cleaning or casting ability. There are many multiple shapes available, but most are square, rectangle or round.
Typical Sizes | Minimum | Maximum |
Length or Diameter (in) | .5" | 6" |
Width (in) | .5" | 6" |
Height (in) | .25" | 1" |
CPSI | 16 | 500 |

Laminar Flow vs. Turbulent Flow
Using a ceramic honeycomb filter improves the quality of molten metal flow. The ceramic honeycomb filters create laminar flow which is superior to turbulent flow. When the molten liquid metal passes through the ceramic honeycomb channel, the debris, the slag and other inclusions are removed. A stable and fast laminar molten metal flow prevents air from getting into the molten metal flow, molten metal getting oxidized and splashing out.
Comparable foam filters have a wide variation in the amount of time it takes liquid to flow through them. Although the result of the designed random pattern creates the “tortuous path”, it increases the time variability and the “splash” effect. Even from filter to filter in the same exact size and PPI the flow can vary considerably (+/- seconds), even in the same filter from pour to pour. This can create problems when trying to control the solidification of the crystals during casting.
The honeycomb filters have very consistent flow as well as generating laminar flow. Having more laminar flow prevents splashing and void inclusions in the castings.
DESIGN SUPPORT
Depending on your company’s needs, our products can be designed specifically for your flow control, strength, and performance. Applied Ceramics began manufacturing ceramic honeycomb in 1980. Since then, ACI continues to offer our world-class engineering support to create more value for its customers and partners and selling into this market since 1984.
