The presence of non-metallic inclusions is detrimental to the production of high-quality castings and the ceramic foam filter provides the best method of eliminating non-metallic inclusions and is a new type of molten metal filter that has been developed in recent years to reduce casting defects.

Foam ceramics are characterized by lightweight, high mechanical strength, large specific surface area, high porosity, good thermal shock resistance, chemical resistance, and high-temperature stability in molten metal. The mesh structure with distributed pores makes for better casting quality. Meeting your increasing quality requirements.

Foam Ceramic Filters

Filtration with foam ceramic filters offers several key advantages to improve the quality of castings. 

These advantages include：

1. Remove impurities, refractory waste, solid refractory alloys, and sintered material from the metal fluid during casting, remove turbulence, reduce casting porosity and improve casting quality.

2. Eliminating turbulence in the metal flow, smoothing the metal flow, and avoiding spatter, splash and reflux.

3. Provides consistent flow and capacity.

4. Improves flowability, castability, machinability, yield, and cost-effectiveness.

5. Removal of more fine particles, reducing scrap and rework.

6. Reduction of dye penetration indications.

7. Reduction of X-ray evidence of non-metals.

8. Various sizes, shapes, and orifice sizes are available.

9. Reduced time spent on quality testing and inspection.

Foam ceramic filters are therefore widely used in the foundry industry for casting/casting of mild steel, stainless steel, iron, bronze, copper, alloys, and aluminum to prevent defects and other inclusions caused by oxides, scum, gases, and slag.
