Sponge foam ball falling rebound tester

model:HY-7721C

Resilience test (ball rebound) Tester

Sponge foam ball falling rebound testerMain application scope and functions:

This machine is designed and manufactured according to GB/T6670-2008, and complies with ASTM American standard D3574 and ISO 8307 testing standards It is suitable for measuring the springback property of soft polyurethane foam The instrument calculates the percentage of the ratio between the zui height of the steel ball rebound and the falling height of the steel ball, namely the rebound rate, by which the rebound performance of the foam plastic is expressed. The machine is controlled by a microprocessor, with a touch screen displaying in Chinese and the ability to print test data. This machine has the characteristics of safe use, reliability, and high measurement accuracy.

Control method:Touch screen+PLC controller, Chinese display, print test data
