We supply ceramic foam filters for foundries. Alumina Ceramic Foam Filter is applied to filter molten aluminium and aluminium alloys. White in color alumina foam filter is made from high purity alumina (AI2O3). It has excellent ability to resist high thermal shock while maintaining efficient removal of impurities with continuous and thorough filtration.
Ceramic foam filters are only developed as a new type of molten metal filter to reduce casting defects. They play a vital role in the metal casting and foundry industries. They are used to filter out impurities in molten metal, improve quality and performance.
A “filter cake” is formed on one side of the inlet filter, and deep filtration is carried out inside the ceramic matrix, so these ceramic foam filters are an effective tool to achieve the metallurgical purity of molten metal during the casting process. The filter also stabilizes the filling of the mold, thereby preventing undesirable defects in the casting. The type of ceramic foam filter especially depends on its application requirements.
In the ceramic industry, foundries ceramic filters are used to filter impurities in molten metal to improve the quality and performance of the final product.
Ceramic foam filters require precise performance under extremely high temperatures and harsh conditions, and must meet the highest standards in terms of performance, durability, and heat resistance. This is where the expertise and engineering expertise of technology bubble services stand out. As a recognized leader in engineering-based foam conversion, our products are used by some of the most well-known foundries around the world for casting aluminum.
Advantage of Foundries Ceramic Foam Filters
- Simplified and shorten gating system, increasing yield.
- High strength without loose ceramic particles or powder
- Remove tiny slag effectively and purify the molten metal.
- Three dimensional connected mesh structure and high porosity
- Well-distributed molten metal and improve performance.
- Quiet laminar flow of molten metal.
- Smaller particles are captured on the filter cake created by the larger particles, finer particles are captured within the pores in the filter.
