Application of Ceramic Foundry Sand in Alkaline Phenolic Resin No-bake Process

For the production of steel castings, sodium silicate no-bake sand, furan resin no-bake sand and alkali phenolic resin are commonly used. Since the 1990s, the above various molding and core-making processes have been tested (practiced) under various adaptive conditions and have been produced for more than 30 years. With the discovery and popularization of Kailin Ceramic Foundry Sand, and the improvement of used sand recycling technology, Alkaline phenolic resin no-bake sand gradually shows the advantages of high-quality steel castings in mass production, and is increasingly becoming the primary choice of molding process for newly-built and reconstructed cast steel mills.
