The compact Aflow extrusion plastometer uses state-of-the-art force control in place of the usual individual weights The advantages of this technology are that it makes melt index determination significantly easier and more reliable. Load application via electromechanical drive provides improved load control during the test. Multi-stage tests in particular, i.e. tests with various test loads, are largely impact-free using this instrument. Residual material at the end of the test can easily be extruded using the maximum test load of 50 kg, saving testing time. It is equipped with a pneumatic device for cleaning the extrusion barrel. This device can also be used for pre-compacting the test material directly after charging. The temperature in the extrusion barrel is generated by four heating elements, allowing for a temperature accuracy of better than +0.3°C over the relevant area of the barrel.
