Product manual:

The MFI-450 melt flow rate tester is used to determine the flowability of thermoplastic polymers at high temperatures, such as polyethylene, polypropylene, polyoxymethylene, ABS resins, polycarbonates, according to the test method of GB / T 3682 , Nylon fluoroplastics and other polymers. The machine adopts the industrial PLC programmable controller, the touch screen operation platform, the Chinese character liquid crystal display. The machine automatic temperature control is divided into manual, time control and automatic cutting method, which can realize the quality method (MFR) and the volume method (MVR) two test methods; the machine can measure the raw material at the test temperature of the melt density, the system also has a temperature calibration function. In this case,

The machine is equipped with micro-printer can print test report, is currently in the same industry in the high-end models, simple operation, stable operation, long time to test, praised by users.
