Die-cast ceramic filters are made from high-purity alumina or silicon carbide ceramics and sintered at high temperatures. They have strong resistance to high-temperature erosion and chemical stability. They can withstand high-temperature metal liquids above 1700 ℃ and do not undergo chemical reactions with alloys such as aluminum, copper, and iron. This ensures no secondary pollution during the filtration process.
The uniform microporous structure can accurately capture small slag particles in molten metal. The infiltration efficiency can be over 98%. This effectively improves the mechanical properties and surface quality of castings.
In addition, ceramic filters have high strength and good thermal shock resistance. They are not easily broken during continuous die-casting operations and have a long service life. They are key consumables to ensure the quality of high-end castings.
