Brabender® single screw measuring extruders and Extrusiograph® are interchangeable measuring heads which, in connection with a Plasti-Corder® Lab-Station or Plastograph®, serve for testing the extrudability of polymers and for studying problems occurring in research and development as well as in practical application. The Brabender® modular system allows the complete instrumentation of the extruders for raw material checks and development. Manifold screws, die heads, and downstream equipment fulfill all kinds of extrusion tasks.
The sample material is plastified under practice-oriented conditions and extruded through the die head. All measuring values such as torque, melt temperature, melt pressure (if requested, screw backforce, too) are recorded continuously and represented in the form of tables and diagrams parallel to the running test.
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 automatically by the WINExt software.
