Product Description
This is a high-precision fully automatic melt flow index tester.
It is used to measure the MFR/MVR value of the melt flow rate of
various plastics and resins through a standard die every 10 minutes
when they pass through a certain temperature and load in the
viscous flow state.
It is suitable for engineering plastics such as polycarbonate,
polyarylsulfone, fluoroplastics, and nylon with higher melting
temperatures.
It is also suitable for polyethylene (PE), polystyrene (PS),
polypropylene (PP), ABS resin, polyethylene Testing of plastics
with lower melting temperatures such as formaldehyde (POM) and
polycarbonate (PC) resin is widely used in plastic production,
plastic products, petrochemical and other industries as well as
related universities, scientific research units and commodity
inspection departments.

Product advantage:
-1.Multi-stage (2-stage) temperature control method, 2 sets of
platinum resistance sensors, 2 heating jackets for independent
temperature control, high-precision intelligent PID control, the
heating slope or heating speed is adjustable
-2.The temperature resolution is 0.1℃, the temperature uniformity
is 0.2℃, the temperature fluctuation within 24 hours does not
exceed 0.5℃, and the displacement sensor resolution is 0.001mm.
-3.Temperature over-temperature protection device
Integrated manual and automatic cutting, cutting time (0~999) and
cutting times (0~999) can be set arbitrarily
-4.When testing, you can choose the mass method, the volume method,
or both testing methods at the same time, and the flow rate ratio
can be calculated. Both methods start testing when the piston rod
moves to a certain position.
-5.It has a built-in temperature stabilization alarm, and adds a
240-second (GB3682 stipulated) material preheating second
countdown. After the countdown is over, a prompt sound will sound,
and the preheating time such as American Standard (ASTM) can also
be set.
-6.A variety of plastic material melt index test conditions are
built-in, which is convenient for customers to call up and use at
any time, reducing tedious workload, and storing the last test
conditions and results.
-7.Built-in micro printer for easy printing of test data
-8.High-precision touch screen controller, 7-inch touch screen, can
store and print recent test conditions and data. The settings of
the test print menu include test time (system default), operator,
material name, test method, test conditions (temperature, weight)
Weight, cutting time interval), test result data, test result
artificial judgment OK or NG, etc.
-9.The RS232 interface or USB interface is reserved to connect to
the computer, and the instrument operation can be controlled
through the computer and the test data can be transmitted and saved
to the computer.
-10.The weight can be loaded manually or the ball screw can be
driven by a stepper motor to automatically control the rise or fall
of the top-loaded weight.
