The 6MPCA is the most advanced model offered within the Ray-Ran range of melt flow indexers. The operating procedure is simple to undertake using its onboard advanced microprocessor technology. The large LCD provides onscreen instructions, reducing user error, and test parameters are easily entered via the keypad. The apparatus can accurately determine results for MFR, MVR and Density at test temperature.

To conduct a test, molten polymer is extruded through a closely controlled orifice (die) from the apparatus using user set test parameters of temperature and pressure produced by a dead weight system. Rotary encoder technology accurately determines piston displacement as the polymer is extruded and automatically starts the test when the piston is in the critical zone for testing.

Simple parameters are entered, such as user names, material reference numbers and batch numbers, which are stored in lists for future recall and results presentation. Other parameters, which are user defined, and multi slicing and hi – lo limits. The multi slicing feature of the unit makes flow curve analysis instantly recognizable when the results are downloaded to the supplied software. The operator inputs data for the amount of slices to be made during the setup process and the microprocessor accurately records the MFR result at each slid during the test.
