Automatic Melt Index Meter

  Melt flow indexer is a kind of instrument testing the melt flow rate of plastic polymer at high temperature on the basis of GB3682-2000, ISO 1133 and ASTM D1238 test methods. It is not only suitable for high melting temperature engineering plastics such as polycarbonate, polyarylsulfone, fluorine plastic and nylon but also suitable for some other low temperature plastic products which are made up of polyethylene (PE), polystyrene(PS), polypropylene(PP), ABS resin, and polyoxymethylene. So it is widely used in the plastic production, petroleum and chemical industry and the scientific research institutes.

Ambient temperature: 10℃-40℃

Relative humidity of environment: 30%-80%
（Used in an environment without corrosive media, strong air convection, vibration, or strong interference.）
　

Correct installation on a solid foundation

There is no strong magnetic field in the use environment, and no strong convection in the air

Power supply: AC110V±10%, 60Hz

Power: 0.5 KW

Two testing methods

For different flow rates, the mass method or volume method can be used for measurement.
MFR: Mass method
MVR: Volume method

Automatic cutting

Manual cutting and automatic cutting are integrated, and the cutting time and interval are set by customers at will.
　

Equipped with a tool rack
The machine is equipped with a tool rack for easy storage and flexible operation.

Automatic calculation and printing
Built in dedicated software, automatically calculates results, and data can be directly printed.

1. Unpack the instrument, check whether all accessories are available, clean the instrument and place it on a relatively stable workbench.

2. Push the pull rod into the instrument body, put the water level gauge into the barrel until the bottom surface of the water level gauge reaches the die baffle, adjust the four adjusting screws, tighten the adjusting screw lock nut and remove the water level gauge.

3. Push the die into the barrel from the top of the cylinder through the loader bar until it reaches the die plate, and put the piston rod (assembly) into the cylinder.

4. Connect the power plug, turn on the power switch on the control panel, and the power indicator will be on. Set the test parameters, press the start button on the test homepage, and start to heat the instrument.

5. When the stable temperature holds 15 minutes, wear the advanced prepared gloves (to prevent burns) to remove the piston rod and then put the samples into the barrel through the hopper. Put the loader bar into the barrel to compact the samples. Then put the piston back into the barrel.

6. Conduct sample cutting in different modes as needed:

(1)Automatic cutting: Press ‘RUN’ when the piston rod’s mark aligns with the barrel opening.

(2)Manual cutting: Press ‘SPIN’ when the piston rod’s mark aligns with the barrel opening.
(Note: For MVR testing, no need to set automatic cutting time and frequency.)

7. After the test is completed, select 3-5 bubble-free samples, cool them, weigh them, take the average value, input it into the instrument, and press "OK" to automatically display the result (MFR or MVR).

8. After finishing the test, clean the instrument thoroughly.

9. Turn off the instrument and pull out the power cord.

1. The individual socket must have a ground wire outlet hole and reliable grounding.

2. If there is any abnormal display on the LCD, please turn it off, then reset the test temperature and start the work.

3. If the furnace temperature is higher than 450℃ under normal operation, the software precaution will work to stop heating and give an alarm.

4. If there is anything abnormal, please turn off the instrument firstly and prepare for maintenance.

5. When cleaning the piston rod, it can’t be scraped with hard objects.

6. Keep hands, clothing and tools away from moving parts while the machine is in operation.
