Foundry Materials Silicon Carbide Ceramic Foam Filter For Casting

Ceramic Foam Filter is a kind of effective molten metal filter that is mainly designed for filtering impurities from grey iron. SiC Ceramic Foam Filters is available in all standard dimensions and different thicknesses. The most common porosity are PPI 10, 20, 30, and 40; higher porosity is available upon request. Custom-made cut-to-size filters are also possible.


Product Features:

1. Precise size. The control of silicon carbide ceramic foam filter for casting size is processed from filter media sponge cutting to the final sinter.

2. High strength and free from loose debris. Special formula and technique adjustment together with the good package are to make sure it prevents debris either during transportation or molten metal pouring.

3. Branded main material. Branded filter media sponge with a strict inspection to make a sure uniform hole with high porosity.Triple check on pores of sponge: before cutting, cutted, sintered.

4. High purity of raw materials, high refractory, and good thermal shock resistance.
