Advanced Casting Materials with Premium Quality

As a key clay sand casting material inherited from traditional clay sand casting system to this day, High-Efficiency Foundry Coal Powder still plays an irreplaceable role in the upgrading of modern casting process, and is an economical and practical high-quality cast iron auxiliary material. Made of high-grade anthracite as raw material, this product adopts environment-friendly processing technology to remove impurities, optimize particle size and increase fixed carbon content, making it exert the best bright carbon formation and isolation protection effect in sand molds, improving casting surface quality from the source. As a professional clay sand casting material, this product can effectively improve sand mold high-temperature performance, reduce molten metal erosion on sand molds, prevent defects such as sand burn, sand inclusion and peeling, improve casting finish and yield. At the same time, it can reduce molding sand moisture, improve air permeability and fluidity, optimize mold…
