GB/T 14235.7-1993 Determination of the flowability of mold materials in focused investment casting. The standard describes the principle of measuring the flow characteristics of mold materials to determine the flowability through specific devices and conditions. Detailed description of the equipment required for the determination, such as the parameter requirements of the flowability meter. Specify the preparation process of mold material samples, clarify the test conditions such as temperature and pressure, and the specific operation steps such as the measurement of the flow distance of the mold material. The standard provides a unified method for the accurate determination of the flowability of the mold materials in investment casting, helping to ensure the mass of the mold materials and ensure the smooth progress of the investment casting process.
