The Ray-Ran MFR200 Microprocessor Melt Flow System measures the melt flow index of thermoplastic materials to ASTM D1238 and ISO 1133, using an automated cut device for improved repeatability. Suitable for plastics manufacturers, compounders and quality control laboratories.
The MFR200 melt flow indexer offers a more automated procedure compared to the MFR100, vastly improving results accuracy for “method A” testing. Designed for manufacturers in the plastics and polymers,automotive and medical devices industries, as well as research laboratories and quality control facilities, the MFR200 helps verify the flow characteristics of thermoplastic materials to support consistent product quality and process control.
Accurate melt flow data helps manufacturers identify batch-to-batch variation in raw materials before it affects production output or finished product quality.
Consistent MFI measurement supports process control during polymer compounding, extrusion and injection moulding, reducing waste and rework.
Compliance with ASTM D1238 and ISO 1133 helps quality and R&D teams validate materials against supplier specifications and internal standards.
The test procedure is very simple to conduct. Molten Polymer is extruded through a closely controlled orifice (die) from the apparatus using pre-set conditions for temperature and pressure, produced by a dead weight system. The extruded polymer is cut off automatically and is then weighed. Using the time interval to extrude the polymer its flow rate over 10 minutes can easily be determined. Test results are given as the Melt Flow Index (MFI). A density at melt temperature test can also be conducted. This enables manufacturers to assess material consistency quickly, helping identify variations before they affect production or finished product performance.
The MFR series of Melt Flow Indexers are supplied as standard with a replaceable hardened steel cylinder liner which can be simply swapped if a replacement is needed or for Hastelloy (optional) if testing corrosive materials is a requirement. A Tungsten Carbide test die and hardened steel piston along with 2.16 kg test load and tooling ancillaries complement the apparatus to get you testing straight out the box.
The apparatus features a rotary “Auto Cut Device” feature for consistent cutting accuracy of the extrudate eliminating the need for manual cutting. Automating this stage improves repeatability and reduces operator variability between tests.
For simplicity of use the apparatus is fitted with an intuitive 4″ color touchscreen panel and microprocessor interface so test parameters can easily be set. Features include, temperature set point value (SV), actual temperature value (AV), number of cuts, cut time, auto MFI calculation and “ECO” mode. Simply weigh the cut samples and enter the weights as a mean or individual cut and let the microprocessor calculate the MFI value. This helps laboratories complete testing more efficiently while maintaining consistent, reliable results.
The integrated temperature controller and PT100 Platinum Resistance Thermocouple accurately control the barrel temperature to 0.01°C. Dual-zone heating gives accurate temperature deviation along the length of the barrel to international test standards. Precise temperature control helps ensure repeatable melt flow measurements and confidence in quality control data.
All documentation is supplied including a product user manual and a fully traceable calibration certificate.
Optional weights up to and including 21.6kg can be supplied to cover all testing parameters to International Test standards and for the heavier weights the optional pneumatic weight loader can be fitted to the apparatus for ease in loading the piston. The weight loader can also be used to hold a cleaning tool so cleaning can be done more simply. The improved die release feature makes removing the test die a simple task.
The MFR200 is supplied with the latest edition of Ray-Ran’s Techni-Test 2 software. Techni-Test 2 allows for graphical and tabular results to be presented and reports to be printed or saved as .CSV files that can be exported and opened in Microsoft Excel if required. Previous saved tests can also be recalled into the software. USB and Ethernet ports are fitted as standard for results file capture as well as direct download to USB Flashdrive. This supports efficient data management, reporting and traceability across laboratory and manufacturing environments.
Although the MFR value is not a fundamental property of the polymer, it does however, give an indication of the flow characteristics of the polymer and it has become one of the most widely used references for the quality control of polymers.
The machine is available in either 220-240v 50Hz or 110-120v 60Hz.

The MFR200 measures the Melt Flow Index (MFI) of thermoplastic materials using Method A testing. Molten polymer is extruded through a precisely controlled die under set temperature and pressure conditions, and the flow rate over 10 minutes is calculated automatically. A density at melt temperature test can also be conducted.
The MFR200 is supplied as standard with a 2.16 kg test load. Optional weights are available from 1 kg up to and including 21.6 kg to cover all standard testing parameters. For heavier weights, an optional pneumatic weight loader can be fitted to ease piston loading and assist with cleaning.
Yes. The standard MFR200 is supplied with a replaceable hardened steel cylinder liner. For testing corrosive materials, an optional Hastelloy cylinder, liner and die are available as a direct replacement, making the instrument suitable for a wider range of specialist polymer compounds.
The MFR200 complies with Method A of ASTM D1238 and ISO 1133, the primary international standards for melt flow rate testing of thermoplastics. Additional international test standards may also be covered depending on the weight configuration selected.
The MFR200 is supplied with Ray-Ran’s Techni-Test 2 software, which presents results in graphical and tabular format. Reports can be printed or exported as CSV files compatible with Microsoft Excel. USB and Ethernet ports are fitted as standard for direct PC connection or USB flash drive export. Previous test results can also be recalled from within the software.
