Application of Foam Ceramic Filter for Casting
Casting is an immensely popular manufacturing process that involves pouring molten material into a mold and allowing it to cool and solidify in the shape of the mold. Nearly two-thirds of all metal products produced in the United States are casted in a vast array of industries. In addition to casting, other popular manufacturing processes include forging, stamping, and machining. Casting is unique in the other processes, however, due to its ability to create complex shapes and thicknesses. Due to the nature of the casting process, it is often required to clean the molten metal before casting for safety and quality reasons, and foam ceramic filter is one of the most popular types of filters for this purpose.
Foam ceramic filter is specifically designed to remove and capture particles and debris from molten metal, like slag and oxides. Due to the larger pores in the ceramic foam, the larger unfiltered particles can easily and quickly be removed. After the cleaning process, the majority of the large particles are removed while allowing the more uniform and refined particles to pass through. The passer rate and pore size of foam ceramic filter is adjustable depending on the needs of the project and application. The resulting pass of molten metal is much more uniform and refined, allowing the casting of higher quality, more precise parts and products.
In addition to its ability to filter impurities and large particles from molten metal, foam ceramic filter also has a temperature resistance that makes it suitable for most projects and applications. With a melting temperature of over 2700 ℃(4872F), this filter is able to withstand longer periods at higher temperatures without warping or deformation, making it a preferred choice for applications that require molten metals at temperatures greater than 600 ℃(1112F). With a thermal expansion coefficient close to 0, foam ceramic filter is able to resist impacts from heat changes over time, meaning it can maintain its shape and integrity for long periods of time.
By combining the temperature resistant properties of foam ceramic filter with its ability to easily and quickly remove large particles and debris from molten metals, it is easy to see why it is so popular for casting applications. It is able to provide superior cleaning and filtering capabilities while requiring lower maintenance costs and providing longer service life. The use of this filter is also able to provide a much higher rate of casting success due to the greater purity of the molten metal, resulting in finished products and parts that are of a more precise quality.
Overall, foam ceramic filter is a great option for a variety of casting applications. With its superior cleaning and filtering capabilities, temperature resistance, and long service life, this is an ideal filter for a wide array of casting projects and needs. With its ability to provide better quality and purer molten metal for casting, the use of this filter can ensure a greater rate of success for any casting efforts.
