Application
This machine is specifically designed for conductive foam. It can accurately measure the stress and resistance values of the foam when it is compressed to a specified height or compression rate. This helps enterprises control the matching degree of the product's conductive performance and mechanical performance. At the same time, it is widely applicable for compressive resistance tests of various conductive flexible products such as conductive foam tapes, conductive films, conductive fabrics, and conductive tapes. It meets the detection requirements of multiple product categories. This machine is also known as conductive foam pressure impedance tester, conductive foam compression resistance tester, conductive tape compression resistance tester, and is compatible with various industry naming conventions.
Test Standard
This machine is strictly designed and manufactured in accordance with multiple national and international standards, ensuring accurate and compliant detection data. It can fully meet the following standard requirements and is suitable for various product detection and certification needs:
National Standard: GB/T 35674-2017 "General Technical Requirements for All-Directional Conductive Sponge for Electromagnetic Shielding"
Test Philosophy
This machine adopts the core testing principle of "electrode pressure application - real-time data collection - data feedback", which is fully automated and precisely controlled throughout the process, ensuring the authenticity and repeatability of the test data: Place the sample to be tested steadily between the two dedicated electrodes. Through the Panasonic servo drive system, the precise screw rod operates, applying uniform and controllable pressure to both sides of the electrodes. During the test, the American high-precision sensor collects real-time force value data of the sample under different compression heights and different pressures. At the same time, through the four-wire BNC shielded test end, the resistance signal is accurately collected. The instrument automatically records and synchronously analyzes the corresponding relationship between force value, pressure and resistance value, forming a complete test curve and data report. The entire process does not require manual intervention, effectively avoiding human operational errors, and ensuring the accuracy and reliability of the test results.
Product Features
● Intelligent computer control: Adopting a fully digital control mode, it enables real-time measurement, high-speed sampling, and synchronous display of the dynamic relationships of key parameters such as test force, pressure, resistance, and displacement. The operation is convenient, intuitive, and efficient.
● Multi-dimensional curve display: It can simultaneously achieve real-time display of various test curves such as load-deformation and load-resistance on the screen, clearly presenting the dynamic changes of compression ratio, compression height, compression force value, and resistance value, facilitating intuitive analysis of product performance.
● Professional data processing: The test data can be directly output as standardized reports. The graphics and data are deeply combined, supporting saving, reviewing, exporting, and sending, meeting the multi-scenario needs of enterprises for quality inspection archiving and customer acceptance.
● Stable transmission system: Equipped with Panasonic servo drives and precise screw rod transmission structure, it runs smoothly with low noise, has precise speed adjustment, and effectively ensures the stability and repeatability of the testing process.
● Multiple safety protections: Equipped with upper and lower limit position photoelectric protection switches, it effectively prevents the test table from exceeding the preset travel; combined with emergency stop switches and software automatic diagnosis, overload protection functions, it provides comprehensive safety protection for the equipment, test samples, and operators.
