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 A Combination of Safety and Functionality
addition to increased operability to improve testing efficiency, accurate temperature measurement and stable control are provided through a reliable
temperature control system.
High Test Force Precision and Wide Pressure Wide Test Temperature Range from
Range up to 50 MPa 20°C above Room Temperature to 400°C
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

Viscosity Evaluation of Thermosetting Resin

Weight-based constant test force extrusion is used to measure the amount of piston movement (movement speed), which is
used to determine viscosity. Highly reproducible measurements of fluidity of thermosetting resins, which cure rapidly due to
heating, can be determined due to the highly precise temperature control and the range of test forces available.

Improved Efficiency MAX 20°C above Room
50MPa Temperature to 400°C
Enhanced labor-savings have been implemented throughout the entire testing process, from setting of the sample and starting the test to output of the
test results. All of this greatly increases the efficiency of production procession, quality control, and research and development testing.
High test force precision is obtained by the weight-based fixed test force The wide temperature range makes it possible to measure a wide range of
loading system. In addition, since the test force can be set over a wide range, materials, including engineering plastics. Furthermore, by using the optional

· The bending press joint (tip of the loading unit) facilitates setting the sample. High-Precision Temperature Control System Focus on Ease of Use and Safety

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.
· Test results are quickly output as a report.
· Use of analysis software permits detailed analysis and graph generation. The temperature control system developed specifically for the flowtester Since the furnace can be rotated up to 90° to the left and right, little
