Ryobi Group Ceramic Foam Filter is suitable for purification and filtration of high-temperature aluminum and aluminum alloy solutions. It can filter non-metallic slag and slag as small as micrometers, making the surface of castings smoother and reducing processing losses.
Filtration can make the molten aluminum fill the cavity more uniformly. The molten metal has a higher tendency of turbulence during the casting process, and finally is transformed into a very stable laminar flow through the turbulent flow of the three-dimensional pore structure. Laminar flow has a better effect on the cavity. The filling, thereby reducing the metal solution pair.
Impact corrosion of the casting cavity, significantly reduce the rejection rate, reduce production costs, and improve labor productivity.

Ryobi Group Ceramic Foam Filter-These filters are only used for aluminum castings.
Currently, the market’s leading suppliers offer various sizes and thicknesses.
You must choose the correct one according to your requirements.
If your requirements are not suitable for common sizes, you can order custom sizes.
In order to avoid re-oxidation of molten aluminum during the casting process, pressureless casting technology can be used.
It improves the productivity of the manufacturer while preparing the filter for the next high-volume shipment.

According to Alitalia, purchasing Ceramic Filter Foundry through sales@adtechamm.com can solve the following problems.
Avoid the presence of inclusions. Make aluminum products more resistant to corrosion and better appearance.
Avoid product defects such as pinholes, looseness, and cracks.
Therefore, the Italian aluminum ceramic filter foundry is a key process in the Italian aluminum aluminum and aluminum smelting.
Commonly used filtration methods for molten aluminum In the modern aluminum liquid purification process, the filter is close to the end of the purification process of the last casting.

Alumina Ceramic Foam Filters are classified according to different apertures, such as 10PPi, 15PPi, 20PPi, 30PPi, etc. The mesh classification of sponge is not the same as the classification of product mesh. Generally speaking, the larger the PPi value, the smaller the corresponding pore size and the smaller the filtered inclusions.

Alumina Ceramic Foam Filters production process
It uses polyurethane foam as a carrier and immerses it in a slurry made of ceramic powder, binder, sintering aid, suspending agent, etc. Then squeeze out the excess slurry so that the ceramic slurry is evenly coated on the carrier frame to form a green body, and then the green body is dried and sintered at a high temperature.
This process is also called organic foam impregnation method, which is a relatively mature production process in China.
