Aflow - the Allrounder

 

A defining feature of Aflow is its high level of automation - easy cleaning and defined pre-compacting at the touch of a button, stepless test-load settings - Aflow adapts to your testing requirements. Aflow was developed specifically for laboratories with high testing volumes; this is reflected in its robust design and convenient operation. It supports all established worldwide standards, including ISO 1133 and ASTM D1238. Aflow can be used to determine melt mass flow rate (MFR) and melt volume flow rate (MVR) to Methods A, B, C and D.

Key advantages and features
1  Advantage and features
 
The new generation melt flow index tester: The Aflow

Optimum test sequence - time-saving and operatorfriendly


The pneumatic pre-compaction feature allows the polymer to be defined and evenly pre-compacted at the press of button-saving time and effort. To further accelerate the procedure after the test, it is possible to eject the remaining material from the extrusion barrel with a force of up to 80kg and then clean it with a pneumatic cleaning device at the press of a button.

 

Flexibility via stepless test load up to 50kg

Test loads in Aflow can adjusted steplessly from 0.325kg to 50kg. A multi-stage test can be performed effortlessly to Method D purely by means of presets in the software. This allows several tests with different weight stages to be carried out with a single barrel filling.

2  Range of application
 

Speed, operator-independence and high test-result reproducibility and repeatability-all these things matter in reserch and development and in 24-hour operation, as in production control.

 

A defining feature of Aflow is its high level of automation - easy cleaning and defined pre-compacting at the touch of a button, stepless test-load setting - Aflow adapts to your testing requirements.

 

Aflow can be operated in stand-alone mode via a mode via a modern touch display or on a PC with ZwickRoell testing software.

 

  • The basic version of the Aflow extrusion plastometer is designed to perform MFR tests in accordance with Methods A, B, C and D. This can be usion an automatic extrudate cutter and balance. Tests can be performed in accordance with the following standards:
  • ISO 1133, ASTM D1238, ASTM D3364, JIS K 7210.
3  Cleaning
Aflow's pneumatic cleaning device enables cleaning and pre-compacting to be preformed at preset pressure. The Clean and Pre-compact option allows variable adjustment of the cleaning and pre-compacting pressure, While a switch on the cleaning unit allows one of the two pressure steps to be selected.
Using touch

Intuitive, workflow-based touch operation

 

The new standardized operating philosophy allows the operator to move easily between instrument and PC and always feel at home.

All test-related settings are grouped logically and are separated from higher-level system settings. The operator is guided through test configuration step by step. The saved test configuration can easily be exported and transferred to other instruments.

Integrated user management allows the operator's input options to be reduced to a minimum. Users see only what is important to them, allowing them to focus on the task at hand right from the start.

The MVR is shown "live" in graphic form in stand-alone mode and in the ZwickRoell testing software. This allows both melting process and behavior to be followed precisely during measurement.

Saving space when testing with multiple instruments

In labs with multiple instruments, testXpert III makes it possible to configure and control up to six Aflow and/or Mflow extrusion plastometers with one PC. Central operation and saving of results at a single workplace increases efficiency and affords a quick overview of all tests currently in progress. For a clear overview of operations, we recommend using two monitors.

The benefits of operating an extrusion plastometer with testXpert III are:

  • Automatic bubble detection that prevents measurement errors caused by air inclusions by detecting them in the plastic melt
  • Live display of the melt volume rate that follows the progress of melting and the behavior during measurement and graphically or numerically displays the test piston speed when the test starts in cm³ per 10 min. or in g per 10 min. when the melt density is preselected
