Purpose

This machine is used to determine the indentation hardness of porous elastic materials. It can test polyurethane sponge foam samples according to national standard methods, accurately measuring the indentation hardness of materials such as sponges and foams. It can also be used to measure the specified indentation hardness of produced seat foams (such as backrest and seat cushion foams), providing precise hardness values for each foam component of a seat.

Principle

In the sponge foam compression stress test, the sample is placed between the upper and lower compression plates. The upper plate compresses the sample of a specified size downward at a set speed until the indentation specified by national standard methods (Method A, B, or C) is reached. The load cell on the upper plate senses the applied pressure and sends the data to the controller for processing and display, thereby determining the indentation hardness of sponge, foam, and other similar materials.

Features

Automatic Zeroing: The system automatically zeroes when the test starts.

Automatic Return: After the sample breaks, the plate automatically returns to its initial position.

Automatic Gear Switching: Different load ranges can be automatically switched to ensure measurement accuracy.

Adjustable Speed: The test speed can be adjusted according to different samples.

Indication Calibration: The system can accurately calibrate force values.

Control Methods: Test methods can be selected based on requirements, including test force, speed, displacement, and strain.

Multi-functional: Equipped with sensors of different specifications, allowing one machine to serve multiple purposes.

Curve Analysis: After testing, the force and deformation data at each point of the curve can be analyzed using a mouse.

Display: The data and test curves are dynamically displayed during the test.

Results: Test results can be stored and analyzed with the data curves.

Limit Protection: Equipped with both program-controlled and mechanical limits.

Overload Protection: The machine automatically stops when the load exceeds the rated value.
