Electronic Plastic Testing Equipment Melt Flow Index Tester meter

Melt Flow Index Tester  GC-MI-DP

A. Product Introduction :

It is used to determine the MFR & MVR value of the melt flow rate through the standard die every 10 minutes when various plastics and gums pass through a certain temperature and load in a viscous flow state. It is suitable for melting high temperature polycarbonate, poly sulfoxide, fluorine plastics, nylon and other engineering plastics. Also, it is appropriate for the poly formaldehyde, polystyrene, polypropylene, ABS resin poly formaldehyde, polycarbonate resin and other low-temperature plastic melting test. The machine is widely use in plastic production, plastic products, petrochemical and other industries and related universities, scientific research units and commodity inspection departments.

B. Test standards:

GB-T3682-2018  Determination of melt flow rate and melt volume flow rate for thermoplastics
ISO1133: 1997  Determination of melt mass flow rate MFR and melt volume flow rate MVR for thermoplastics
ASTM D1238  Standard test method for determination of flow rate of thermoplastics melt by extruded plastometer

C.Feature:

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 and the heating speed are adjustable

2. The temperature resolution is 0.1°C, the temperature uniformity is 0.2°C, the temperature fluctuation within 24 hours does not exceed 0.5°C, and the displacement sensor resolution is 0.001mm.

3. Over-temperature protection device

4. Manual and automatic cutting is integrated, and the cutting time (0~999) and cutting times (0~999) can be set arbitrarily

5. The mass method, the volume method, or the two test methods can be selected for the test at the same time, and the flow rate ratio can be calculated. Both methods start the test when the piston rod moves to a certain position.

6. Built-in temperature stability prompt alarm, and add 240 seconds (specified by GB3682) to count down the material preheating seconds. After the countdown is over, a prompt tone will sound, and the preheating time such as American Standard (ASTM) can also be set.

7. Built-in multiple melt index test conditions for plastic materials, convenient for customers to call and use at any time, reduce tedious workload, and store the last test conditions and results

8. Built-in micro-printer for easy printing of test data

9. High-precision touch screen controller, 4.3-inch touch screen, can store and print the latest 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 code weight, cutting time interval), test result data, test results are manually judged OK or NG, etc.

10. Reserve RS232 interface or USB interface to connect to the computer, you can control the operation of the instrument and transfer the test data to the computer through the computer.

11. Pre-placed weights on weight brackets allow for electric loading and unloading, reducing manual handling.

D. Product usage:

1. This kind of instrument can be used to test the melt flow rate(MFR) figures of all kinds of plastic and resin in the viscous flow state. It is not only suitable for the high melting temperature engineering plastics of 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, polyoxymethylene(POM) and polycarbonate. So it is not only widely used in the plastic production, petroleum and chemical industry but also in the relevant institutions such as scientific research units and the community inspection departments.

2. The melt flow rate instrument is suitable for measuring the thermoplastic melt mass flow rate following the determination in the standard ”GB/T3682-2000 thermoplastic melt mass and volume flow rate measurement”. The standard is equivalent to the requirement in the ISO 1133:1997 and can meet the ASTM D1238 test.

3. Considering the beautiful appearance and convenient operation ,the desktop structure of the melt flow rate instrument makes the equipment performance reliably and stably. Besides, the high-precision control instrument using fuzzy PID algorithm for temperature control has the feature of high sampling precision and high speed control.
