MeltFlow Testing

  • AFlow Extrution Plastomester Zwick

    Applicational range

    The Aflow is noted for having a high degree of automation: whether simple cleaning and defined pre-compacting at the press of a button, or infinitely settable test loads – the Aflow adapts to your test tasks. The extrusion plastometer supports all globally common standards and procedures, including ISO 1133, ASTM D 1238 according to Methods A, B, C and D.

    The pneumatic precompacting feature allows the polymer to be defined and evenly precompacted at the press of a button – saving time and effort. Furthermore, testXpert II determines the test results in the automatic parameter control, so that the Aflow automatically selects the correct test parameters. This precompacting feature gives you a high degree of user independence even if the testers change often. To further accelerate the test procedure after the test, you have the possibility to eject the remaining material from the extrusion barrel with a force of up to 80 kg and then to clean the extrusion barrel with a pneumatic cleaning device at the press of a button. Space-saving, multi-device operation lets you connect up to six Aflow or Mflow extrusion plastometers to a PC. Of course, you can also use the Aflow in Stand Alone Mode without a PC.

  • CFlow Extrution Plastomester Zwick

    Applicational range

     The Cflow is a compact instrument that allows rapid determination of the Melt mass flow rate of plastics. It is specifically designed for the processors of plastics that are less subject to extrusion tests and which do not require a connection to a PC.

    The temperature control of the heating elements, the heating chamber and the extrusion barrel are perfectly matched to each other. The temperature is generated where it is needed. That ensures an excellent distribution of temperature across the full height of the barrel from the outset.

    Rapid device control is facilitated by the test granulate contained in the scope of delivery. Addition control options are available for the temperature in the extrusion barrel, for the diameter of orifices and barrels with plug gages. An automatic or manual extrudate cutter, a separating door and a die plug are optionally available for the Cflow.

  • MFlow Extrution Plastomester Zwick

    Applicational range

    The Mflow is a modular, expandable device with which you can determine the melt mass and melt volume flow rate. Affordable to setup and gradually expand at any time.

    You can optionally expand the Mflow with, for example, the pneumatic weight lifting unit or the weight pegging unit. The extrusion plastometers are equipped with heating elements that are specially adapted to the thermal conditions of extrusion barrel and device covers. This achieves a very good distribution of temperature over space and time.

    Operation of the Mflow via a PC offers all the advantages of testXpert II: up to six devices per PC can be operated, the traceability of the results and their further processing with testXpert II LIMS is possible for a statistical check and as long-term statistics.
