Efficient Testing with a Reliable Evaluation Method

High test force precision, provided by a weight-based constant test force loading system, enables high measurement reproducibility and test efficiency. In
addition to increased operability to improve testing efficiency, accurate temperature measurement and stable control are provided through a reliable
temperature control system.

Evaluation of Softening and Flow Beginning Temperature
Using Constant Heating Rate Testing

Testing methods include a constant temperature method a constant heating rate method. The constant heating rate method
permits measurement of resin softening temperature and flow beginning temperature to determine shear rate and viscosity at
each temperature and cannot be conducted using other capillary type rheometers. Constant Heating

test results. All of this greatly increases the efficiency of production procession, quality control, and research and development testing.

Setting the Sample

· Selecting test conditions causes the cylinder temperature to rise to the set
temperature.
· The bending press joint (tip of the loading unit) facilitates setting the sample.

Test Start

· The test starts automatically by pressing the start button.
· A stable test force is achieved using the loading weights.
· The test continues until extrusion is complete.
· A cylinder cover ensures that testing is conducted safely.

Output of Test Results

· Temperature and test status can be monitored in real time.
· Monitoring viscosity in real time enables to make a judgment on normal/abnomal values.
· Test results are quickly output as a report.
· Use of analysis software permits detailed analysis and graph generation.
