Precision Ball Screw Foam Indentation Force Deflection Tester
Description:
This machine is used to measure the concave hardness of porous
elastic materials. The polyurethane sponge foam sample can be
tested and tested according to the national standard, and the
hardness of the sponge, foam and other materials can be accurately
measured. It can also be used to measure the specified indentation
hardness of the seat foam (such as the backrest, cushion foam,
etc.) that has been produced, and accurately measure the
indentation hardness of each foam member of the seat.
Principle:
The sponge foam compressive stress test places the sample between
the upper and lower platens, and the upper platen compresses the
sample of a certain size downward at a predetermined speed to the
concavity specified by the A method (B method, C method) required
by the national standard. At the time, the load element on the load
feedbacks the sensed pressure to the controller for processing and
display, thereby measuring the indentation hardness of materials
such as sponges, foams, and the like.
Functional characteristics:
1. Automatic clearing: After the computer receives the test start
command, the system will automatically clear it.
2. Automatic return: After the sample is broken, it will
automatically return to the initial position.
3. Automatic shifting: According to the size of the load, different
gear positions can be switched to ensure measurement accuracy.
4. Change speed: This machine can change the test speed arbitrarily
according to different samples.
5. Indication verification: The system can achieve accurate
calibration of force values.
6. Control method: Test methods such as test force, test speed,
displacement and strain can be selected according to the test
requirements.
7, a multi-purpose machine: equipped with different specifications
of the sensor, can achieve a multi-purpose machine.
8. Curve traversal: After the test is completed, the mouse can be
used to find out the point-by-point force value and deformation
data of the test curve and analyze it.
9. Display: Dynamic display of data and curve test process.
10. Results: The test results are accessible and the data curve is
analyzed.
11, limit: with program control and mechanical limit.
12. Overload: Automatically stops when the load exceeds the rated
value.
