Melt Index Tester

The Melt Index Tester is designed to determine the melt flow rate (MFR) of thermoplastic materials under specified temperature and load conditions. It uses a heated barrel and extrusion die to measure the flow behavior of molten polymers, providing useful data for material characterization, production quality control, and comparison between polymer batches.

The instrument uses automatic sampling and balance weighing to measure the mass of extruded material and calculate the melt flow rate. It features fast heating, stable temperature control, adjustable test parameters, and manual or automatic cutting modes. Test results are displayed on an LCD screen and can be printed automatically.
