Precision casting sand is a sand mold material specifically designed for high-precision casting. It is usually made of special materials such as quartz sand and resin, which have high strength and fire resistance after processing and treatment, and can be made into very complex sand molds. Characteristics of precision casting sand 1. High precision: Precision casting sand has high detail accuracy and surface smoothness, and is widely used in high-precision casting. 2. Good thermal stability: Precision casting sand has good thermal stability at high temperatures, is not easily deformed, and can maintain good casting accuracy. 3. Easy to process: Compared to other sand mold materials, precision casting sand is relatively easy to process and can be made into various complex shapes of sand molds. 4. Good reusability: The processed precision casting sand can be reused multiple times, reducing the cost of sand mold materials and their impact on the environment. Application of Precision Casting Sand Precision casting sand is widely used in high-precision casting processes, such as aviation engine blades, aerospace, automotive components, and other fields, especially in parts that require high-precision casting. It can improve the surface smoothness and detail accuracy of castings, ensuring the accuracy and quality of parts. In short, precision casting sand is a very important sand mold material that can greatly improve the accuracy and surface quality of castings, and is widely used in the fiel
