Sponge Indentation Hardness Testing Machine Used To Measure The Indentation Hardness Of Porous Elastic Materials

I. Usage:
This machine is used to measure the indentation hardness of porous elastic materials. The polyurethane sponge foam samples can be tested in accordance with the national standards, accurately measuring the indentation hardness of materials such as sponge and foam. It can also be used to measure the specified indentation hardness of already produced seat foams (such as backrest and seat cushion foams, etc.), accurately determining the indentation hardness of each foam component of the seat.
Ii. Principle
In the sponge foam compression stress test, the sample is placed between the upper and lower pressure plates. When the upper pressure plate compresses the sample of A certain size at a specified speed to the concave degree specified by Method A (Method B, Method C) as required by the national standard, the load cell on it will feed back the sensed pressure to the controller for processing and display, thereby measuring the indentation hardness of materials such as sponge and foam samples.
Iii. Functional Features
1. Automatic zeroing: After the computer receives the command to start the test, the system automatically zeros.
2. Automatic return: After the sample breaks, it automatically returns to the initial position.
3. Automatic gear shifting: Different gears can be switched according to the size of the load to ensure measurement accuracy.
4. Speed adjustment: This machine can adjust the test speed at will according to different samples.
5. Indication verification: The system can accurately calibrate the force value.
6. Control method: According to the test requirements, test methods such as test force, test speed, displacement, and strain can be selected.
7. Multi-functionality in one machine: Equipped with sensors of different specifications, it can be used for multiple purposes with one machine.
8. Curve traversal: After the test is completed, the force value and deformation data of each point on the test curve can be found and analyzed at will by using the mouse.
9. Display: Dynamic display of data and curves during the test process.
10. Results: The test results can be accessed and analyzed for the data curves.
11. Limit: It has both program-controlled and mechanical limit functions.
12. Overload: The machine will automatically shut down when the load exceeds the rated value.
