Melt Flow Index Tester (MFI) Digital

The Melt Flow Index Tester – Digital Auto Cut Model from 4B Testing Equipments Pvt. Ltd. is a high-precision laboratory instrument designed to determine the Melt Flow Rate (MFR) and Melt Volume Rate (MVR) of thermoplastic materials under controlled temperature and load conditions. The tester features an automatic sample cutting mechanism, ensuring consistent specimen collection, improved accuracy, and enhanced repeatability while minimizing operator intervention.

The Digital Auto Cut Melt Flow Index Tester is widely used by plastic manufacturers, polymer processing industries, masterbatch manufacturers, research laboratories, quality control departments, and educational institutions to evaluate the flow characteristics of molten polymers during production and material development.

The instrument is equipped with a Digital PID Temperature Controller, high-precision heating system, and automatic timer for accurate temperature regulation and reliable testing. The Auto Cut System automatically cuts the extruded polymer at preset intervals, eliminating manual cutting errors and providing precise and repeatable MFR measurements.

The tester is suitable for testing a wide range of thermoplastic materials, including Polypropylene (PP), Polyethylene (PE), HDPE, LDPE, LLDPE, ABS, PVC, Polycarbonate (PC), PET, PBT, Nylon (PA), Polystyrene (PS), POM, EVA, Engineering Plastics, and Masterbatch Materials.
