GB/T 14235.7-1993

This standard specifies a testing method to measure the fluidity of pattern materials used in investment casting, which is critical for ensuring that the molten wax or plastic can completely fill complex mold cavities. It is applied in the metallurgy and precision casting industries, specifically for quality control of pattern materials during the production of investment castings, such as turbine blades or jewelry. The method helps manufacturers evaluate and select materials that will produce defect-free, detailed castings by simulating the flow behavior under controlled conditions.
