The melt flow index tester is used for testing the melt flowability of thermoplastic polymers at high temperatures such as polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, nylon fluoroplastics and other high polymer. The machine adopts the industrial PLC programmable controller, touch screen operation platform, with micro-printer, to print test report. Automatic temperature control, operation method is divided into manual, time control, automatic three kinds of cutting way, can realize MFR and MVR two test methods. The machine also can measure the the melt density of raw material at the test temperature, the system also has a temperature calibration function.

     The machine is high-end models in the same industry, simple operation, stable operation, long time to test, praised by users. In line with ASTMD1238, BS2782, ISO1133 and others.

Standard test load (kg, total of eight)

Level 1: 0.325kg = (piston rod + weight tray + insulation set +No.1 weight) = 3.187N

Level 2: 1.200 kg = (0.325 + No.2 weight 0.875) = 11.77 N

Level 3: 2.160 kg = (0.325 + No.3 weight 1.835) = 21.18 N

Level 4:  3.800 kg = (0.325 + No.4 weight 3.475) = 37.26 N

Level 5: 5.000 kg = (0.325 + No.5 weight 4.675) = 49.03 N

Level 6: 10.000 kg = (0.325 + No.5 weight 4.675 + No.6 weight 5.000) = 98.07 N

Level 7: 12.500 kg = (0.325 + No.5 weight 4.675 + No.6 weight 5.000 + No.7 weight 2.500) = 122.58 N

Level 8: 21.600 kg = (0.325 + No.2 weight 0.875 + No.3 weight 1.835 + No.4 weight 3.475 + No.5 weight 4.675 + No.6 weight 5.000 + No.7 weight 2.500 + No.8 weight 2.915) = 211.82 N
