MFI MFR Testing Machine Product introduction:

It is designed  with GB/ t3682-2018, ASTM D1238, JB/T5456, ISO1133 standards, for the determination of thermoplastic melt mass flow rate (MFR) and melt volume flow (MVR) instruments.To measure the mass flow rate of the melt, manual and automatic sampling is adopted, and the interval of cutting is prompted by the alarm of the computer, and the balance is weighed. measurement of melt volume flow rate is through the displacement sensor and automatic timing system, first measure the required time for the piston to move the specified distance, and then calculate the volume flow rate according to the formula.The final results of the two methods are printed out by a microprinter.

MFI MFR Testing Machine Character

Melt index instrument color touch-screen display, PLC control machine control, circuit modular, measurement data is accurate, the operation is simple, intuitive and clear, stable and reliable performance, it is not only applicable to the high melting temperature of polycarbonate (PC), fluorine plastic, nylon and other engineering plastics, can also be applied to polyethylene (PE), ABS resin with lower melting temperature, such as plastic test, widely used in plastic production, plastic products, petrochemical and other industries as well as universities and colleges, scientific research units, the commodity inspection department.
