Digital Melt Flow Index Tester
A Digital Melt Flow Index Tester is a critical instrument used in the plastics industry to measure the flow rate of molten polymers under specified temperature and pressure conditions. This equipment helps determine the Melt Flow Rate (MFR), which is crucial for understanding the viscosity of thermoplastic materials. The tester works by extruding a polymer through a standardized die using a specific weight, and then calculates the rate of flow in grams per 10 minutes.
Modern digital versions come equipped with automated controls, touchscreen interfaces, and advanced data analysis capabilities, ensuring higher accuracy and repeatability of results. The automation allows for easy control of parameters such as temperature, weight, and time intervals. Furthermore, digital testers often feature real-time data logging, making them an integral part of quality control processes for materials used in injection molding, extrusion, and other manufacturing processes.
This tool adheres to international testing standards such as ASTM D1238 and ISO 1133, ensuring consistency and reliability in results across various applications. By using a digital tester, manufacturers can maintain product quality, optimize processing conditions, and reduce production costs through better material selection and efficient production
