Simulate production realistically on a laboratory scale. Brabender? single screw measuring extruders and Extrusiograph? are inter?change?able measuring heads which, in connection with a Plasti-Corder? Lab-Station or Plastograph?, serve for testing the extruda?bility of polymers and for studying problems occurring in research and develop?ment as well as in practical application. An important example for the manifold test methods are viscosity measurements with a measuring extruder equipped with a rheometric capillary die head. The relevant data are recorded and evaluated auto?matically by the WINExt software.
