Ball Screw Foam Indentation Force Deflection Tester
This precision testing machine measures the concave hardness of porous elastic materials including polyurethane sponge foam. Designed to comply with national standards, it accurately determines the hardness of sponge, foam, and similar materials, as well as the specified indentation hardness of manufactured seat foam components.
Testing Principle
The foam compressive stress test positions samples between upper and lower platens. The upper platen compresses the sample at a predetermined speed to achieve the concavity specified by national standard methods (A, B, or C). A load element senses pressure and feeds back to the controller for processing and display, enabling precise measurement of material indentation hardness.
Functional Characteristics
Automatic clearing system upon test initiation
Automatic return to initial position after sample break
Automatic gear shifting based on load for measurement accuracy
Variable test speeds adaptable to different samples
Force value calibration and verification system
Multiple control methods: test force, speed, displacement, and strain
Multi-purpose capability with different sensor specifications
Curve analysis with point-by-point force and deformation data
Dynamic display of test data and curves during operation
Comprehensive test results and data curve analysis
