Product Description

Product Description

Sponge fatigue tester/Rubber Foam repeated impact hardness test machine/Ball rebound testing machine
Purpose:
This tester is used to measure the concave hardness of porous elastic materials. It can measure the polyurethane sponge foam samples and carry out the tests specified in the our country standards, and accurately measure the indentation hardness of sponges, foams and other materials. It can also be used to measure the specified indentation hardness of the produced seat foam (such as backrest, seat cushion foam, etc.), and accurately measure the indentation hardness of each foam part of the seat.
This tester can also be used for the reciprocating compression test of foamed polymer materials to determine the residual deformation rate. From this, it is possible to understand the dynamic fatigue properties of the material.

Sponge fatigue tester/Rubber Foam repeated impact hardness test machine/Ball rebound testing machine

Principle:
The sample is placed between the upper and lower platens, and the upper platen compresses the sample of a certain size downward at a specified speed to the concavity specified by the A method (B method, C method) required by the national standard. When the load cell on it feeds back the sensed pressure to the controller for processing and display, the indentation hardness of materials such as sponge and foam can be measured.

Features

1. Automatic reset: After receiving the test start command, the system will automatically reset.

2. Automatic return: After the sample is broken, it will automatically return to the initial position.

3. Change the speed: The machine can arbitrarily change the test speed according to different samples.

4. Indication calibration: the system can realize accurate calibration of force value.

5. Control method: Test methods such as test force, test speed and displacement can be selected according to the test needs.
