 Extrusiograph 19/25 D |
Single Screw Extruders
Simulate production realistically on a laboratory scale
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.

User-optimized 32-bit software under Windows© 98/2000 or XP
The comfortable 32-bit software allows real multitasking. Several tests can be run and controlled on various instruments while texts or spreadsheets can be edited - all at a time from a single computer. Enter your test parameters from your computer keyboard, store them in MS Access database format together with the measuring data and results, and easily use them in other applications like word processing programs or spreadsheets.
Definition of reference curves with tolerance limits makes it easy to check already during the test whether a material meets the specifications for a certain application or not.
A powerful correlation program compares diagrams and results of up to 15 tests with each other. Test conditions and results are contrasted in tables and evaluated statistically for quickly assessing trends or irregularities.
Additional software packages enable programming of speed profiles, e.g. slow premixing and increasing or decreasing mixing speed during the test. This supplementary software can also evaluate diagrams that do not have the typical shape of a standard Plastogram.The melt temperature is also measured and recorded during the test.
