Casting is a vital link in the manufacturing industry, and in the casting process, silicon carbide ceramic foam filters are one of the indispensable tools. These filters have a wide range of pore sizes. The common 10-40PPI pore size can meet the filtering needs of different cast iron parts, but for different types of molten iron and specific application scenarios, choosing the right pore size is crucial.
First, let’s look at the 10PPI silicon carbide ceramic foam filter. This larger pore size filter is suitable for processing ductile iron with high fluidity requirements. For example, in the automotive manufacturing industry, when producing parts such as automobile engine blocks that require high fluidity, 10PPI filters can effectively filter out larger inclusions and improve the surface quality and mechanical properties of castings.
On the other hand, 30PPI silicon carbide ceramic foam filters provide higher filtration efficiency and are suitable for ductile iron parts with higher surface quality requirements. For example, parts used in automotive brake systems require high-quality surfaces, and 30PPI filters can provide the required filtration accuracy to ensure that castings meet high standards of surface quality.
For iron castings that require high precision and mechanical properties, 40PPI silicon carbide ceramic foam filters are an ideal choice. High-precision mechanical parts in the aerospace field are a typical example. These parts have extremely high precision requirements, and the 40PPI filter provides excellent filtration accuracy, which can effectively filter tiny inclusions and ensure that the castings meet high precision requirements.
Therefore, in the casting field, it is very important to choose the appropriate silicon carbide ceramic foam filter pore size. Carefully consider the type of molten iron and the requirements of the iron castings, and choose the correct filter pore size to maximize the quality of the castings and production efficiency, and meet the stringent requirements of different industries for casting quality.
