Ceramic foam filter of aluminum is used to remove the oxide inclusions and provide high-quality molten aluminum for the casting process. Before the ceramic foam filter (CFF) filters the molten aluminum, it is necessary to fully preheat the ceramic sheet and the filter box to ensure that the molten aluminum can pass through the filter […]

Ceramic foam can be divided into two categories, namely, open hole (net) ceramic material and closed-cell ceramic material, depending on whether each hole has a solid wall. If the foam solid is only included in the hole, it is called an open hole ceramic material whose pores are interconnected. If there is a wall surface, […]
Porous Ceramic Filter Filtration can remove alumina and other nonmetallic compounds, such as lithium oxide from the molten aluminum lithium alloy. The porous ceramic filter may be a cellular structure or a foam with interconnect pores. As everyone knows, in order to remove alumina from molten aluminum or aluminum alloy, aluminum or aluminum alloy is […]
Cake filtration is the most common mechanism in which the foam ceramic foundry filters acts as a sieve and retains particles larger than its pore size on the surface of the filter. These retained particles then form a screen and capture particles smaller than the filter aperture. As the cake accumulates on the surface of […]
Foam ceramic filter board has advantages: high dimensional accuracy, high mechanical strength, stable chemical composition, corrosion resistance to liquid aluminum and its alloys, no phosphorus and environmental friendliness, purifying aluminum liquid, improving aluminum quality, reducing defects, reducing defective rate, reducing cost, increasing production efficiency, and using simple and flexible size from 40mm to 600mm to […]
Metal foam filter manufacturing process uses the web polyurethane foam as the carrier, makes the foam plastics evenly soaked to infiltrate the ceramic slurry, and then repeatedly squeezes the foam plastics to remove the excess slurry, so that the ceramic particles are fully removed. Evenly attached to the top of the foam plastic. Finally, it […]
When evaluating a ceramic foam filter for molten aluminum filtration, many buyers focus on pore size, dimensions, or price. However, the manufacturing process often has a greater impact on filtration efficiency than any specification listed on a datasheet. The quality of a ceramic foam filter is determined by raw material selection, slurry formulation, pore structure […]
The aluminum oxide foam ceramic filter plate can effectively remove inclusions from micron-sized fines in aluminum water and make aluminum water into stable laminar flow, which is good for punching. It has a unique mullite corundum structure, good mechanical strength, and chemical stability, superior aluminum water scouring performance, and strict control of pore size and […]
CFF for Molten Aluminum is the most effective and reliable means to remove non-metallic inclusions in the aluminum melt, and is the most effective filtering method. The deep bed filter is large in size, it takes time and effort to install and replace the filter medium, and it is only suitable for the production of […]
Foam ceramic is a kind of porous material. Foam Filter Material for Aluminum Foundry is a third-generation porous ceramic product, developed after the first-generation common porous ceramics and the second-generation honeycomb porous ceramics. Its pore size ranges from nanometer to micrometer, and it has three-dimensional network structure and high porosity material characteristics, and the porosity […]
