Introduction
Ceramic foam filters can significantly improve the quality of metal parts in the casting industry and reduce scrap rates, and can also be used in the continuous casting and rolling process and can be manufactured in all standard sizes and different thicknesses. It uses a three-dimensional structure to effectively remove oxidizing inclusions and other nonmetallic inclusions by blocking capture and adsorption. Whether it is gray iron, ductile iron or shaft body, cylinder body or complex large parts, precision hardware parts and aerospace superalloy precision castings of metal solutions filtered, product quality will be satisfactory results.

PPI and Thickness of Ceramic Filter Foam
The mesh of the filter screen is generally divided into 10P, 15P, 20P, 25P according to the size, and the thickness is divided into 10mm, 15mm, 20mm, 25mm, 30mm, etc. Most factories generally choose mesh 15P, 20P thickness 20mm. If the filter effect is not satisfied with the selection of a thicker filter, pay attention to a problem, the thickness of the plane area is generally increased by 2% per 1 mm.

Foam ceramic filters have broad application prospects in many fields:
1. Chemical industry: Ceramic foam filters can be used to filter and separate impurities and particles in chemical reactions to improve the purity and quality of products.
2. Pollution control: Foam ceramic filter can be used to remove particles and harmful gases in the air to improve environmental quality.
3. Electronics: In the electronics industry, foam ceramic filters can be used to manufacture electronic components and circuit boards to improve product performance and stability.
4. Metallurgical industry: Ceramic foam filters can be used to purify liquid metal in the metallurgical industry, remove impurities and particles, and improve product quality.
5. Construction field: foam ceramic filters can be used for building sound insulation, heat insulation, fire prevention and other aspects to improve the performance and service life of buildings.
