This standard specifies the physical performance test method of medium temperature mold materials for investment casting, which aims to evaluate the performance and Stability of mold materials in practical applications. The standard includes the determination methods of key physical properties such as density, flexural strength, compressire strength, thermal expansion performance of mold materials. These test methods not only help manufacturers to confirm product mass, but also guide users to make accurate evaluations when selecting and using mold materials. It is suitable for all kinds of medium temperature mold materials for investment casting, such as silicate, aluminum oxide, graphite, etc., especially in industrial applications under high temperature and high voltage environment, which has important technical guidance significance. The implementation of this standard will help to improve the standardization level of mold materials, promote the optimization of investment casting processes, and extend the life of molds, thus promoting the technological progress and economic benefits of the entire industry.
