Product Description
Foam Rebound Tester(HD-F754) Main function: The machine is in accordance with the GB/T6670-2008 design and manufacturing, with ASTM D3574 and ISO8307 American Standard testing standards. At the same time with the Japanese car seat test methods forurethane foam SES N3296. Suitable for performance ball rebound off thedetermination of soft polyurethane foam. This instrument is given by steel balldiameter and quality at a specified height free fall on the foam sample the maximum height of the ball, and the calculation of ball rebound height of fall the percentage of both the rebound rate, said resilience foam to rebound rate. This machine uses the microprocessor to control, liquid crystal Chinese display, and print the test data. The machine has the advantages of safety, reliability, high measuring accuracy.

User-Friendly and Efficient OperationDesigned for ease-of-use, the device features a user-friendly control panel, manual or automatic control modes, and a clear observation window. The platform accommodates specimens of 100 x 100 x 50 mm, providing flexibility while maintaining measurement accuracy and efficiency during testing.
FAQs of Foam rebound tester:
Q: How is the foam resilience measured using this Foam Rebound Tester?
A: The foam resilience is measured by dropping a 16 mm diameter steel ball from a height of 150 0.5 mm onto a cylindrical foam specimen. The rebound height is observed through the graduated scale and displayed on the digital LED screen, giving results within the 0-80% range with 1% accuracy.
Q: What type of foam samples can be tested with this equipment?
A: This tester is suitable for soft to medium foam types, requiring cylindrical specimens sized at 100 x 100 x 50 mm. It can test between 1 to 3 specimens per session, providing flexibility for various foam applications.
Q: When should calibration be performed on the Foam Rebound Tester?
A: Calibration is performed prior to delivery and a calibration certificate is included. Periodic calibration, as per your laboratorys quality management system, is recommended to maintain testing accuracy and reliability.
Q: Where can the Foam Rebound Tester be used efficiently?
A: This bench-top, semi-automatic device is ideal for use in manufacturing plants, research labs, quality control departments, and foam product development facilities, ensuring convenient installation and operation in varied environments.
Q: What is the process for setting up a test using the Foam Rebound Tester?
A: Prepare a cylindrical foam sample, secure it in the sample holder, and position the steel ball at the set drop height. Select manual or automatic mode via the control panel, then initiate the test. The rebound is measured visually and digitally, ensuring quick and accurate results.
Q: How does using this tester benefit manufacturers and suppliers?
A: Manufacturers and suppliers benefit from consistent, accurate, and fast measurements of foam elasticity and recovery, supporting product development, compliance with international standards, and reliable performance assurance for foam products.
