    The 6MBA is the basic model offered within the Ray-Ran Range of Melt Flow Indexers. The manually operated test procedure is very simple to undertake. Molten Polymer is extruded through a closely controlled orifice (die) from the apparatus using pre set conditions of temperature and pressure produced by a dead weight system. The extruded polymer is cut off manually and is then weighed. Using the time interval to extrude the polymer its flow rate over 10 minutes can easily be determined, thus giving the Melt Flow Index (MFI) or Melt Mass Flow Rate (MFR) in g/10 min. By conducting a simple Density Test at test temperature on the same material using the same pre set conditions and a known piston travel distance the Melt Volume Rate (MVR) can also be determined.

    The 6MPCA is the most advanced model offered within the Ray-Ran Range of Melt Flow Indexers. The operating procedure is very simple to undertake using its on board advanced microprocessor technology. The large liquid crystal display (LCD) provides simple on screen instructions reducing user error and the test parameters are easily entered via the alpha numeric membrane keypad. The apparatus can accurately determine results for MFR, MVR and Density at test temperature.

  • Ray-Ran – Advanced Universal Pendulum Impact Tester

    The Ray-Ran Advanced Universal Pendulum Impact Tester utilises advanced microprocessor technology to determine the energy required to break or rupture specimens such as plastics, composites, ceramics and non ferrous metals to International testing methods for Izod, Charpy and Tension Impact Testing.

    To calculate the impact energy, the apparatus uses advanced and highly accurate rotary encoder technology to record the lost angle of the hammer after impacting a test sample against the angle recorded after calibrating the hammer. The resulting lost angle is calculated as the test sample’s impact energy by the advanced microprocessor system.

    The apparatus is supplied as standard with Ray-Ran’s Techni–Test Windows based PC software for connection to the apparatus via an RS232 or Ethernet connection. Test results can be printed directly from the Techni–Test software or can be saved and exported as .CSV files which can be opened with Microsoft Excel in tabular form which can be manipulated to your specific requirements such as preparing a graphical presentation or copying the results to a Word document for a report presentation if required.

  • Ray-Ran – Apparent Bulk Density Apparatus – ASTM D1895 Method A

    Bulk density apparatus is testing equipment used to measure the bulk density property of powder, granules and other “divided” solids, especially used in reference to mineral components (soil, gravel, sand), chemical substances, (pharma...

    Bulk density apparatus is testing equipment used to measure the bulk density property of powder, granules and other “divided” solids, especially used in reference to mineral components (soil, gravel, sand), chemical substances, (pharmaceutical), plastics like polyethylene (hdpe or mdpe) pvc, polystyrene etc, or foodstuff and any other masses of granular or particulate matter.

    The Method A tester is primarily used to measure the apparent density of fine granules that can be poured readily through a “V” shaped funnel, the material under test is allowed to flow into a cylindrical cup with a known volume of 100cm³.

  • Ray-Ran – Auto Density Measurement System

    The Auto Density Gradient Apparatus from Ray-Ran has become the world’s benchmark for accurate density measurement of small solid specimens using the column method. Offered as a 3 or 6 column version, the built-in on-board Microprocessor System ...

    The Auto Density Gradient Apparatus from Ray-Ran has become the world’s benchmark for accurate density measurement of small solid specimens using the column method. Offered as a 3 or 6 column version, the built-in on-board Microprocessor System accurately calculates the specimen’s density more quickly and more accurately by using the latest linear encoder technology that measures the samples position in the column relative to the calibrated glass marker floats. Once the correct position of the sample is recorded the density is displayed on the LCD screen.
