This machine is used to test the rebound performance of rubber products after a certain time and pressure. Take the standard test pieces, lay them flat on the test plate, sandwich them between the two plates of this unit, take them out after the specified time, release the test pieces and cool them down, measure the final center thickness of the test pieces respectively, and substitute into the formula to find the compression rebound rate.

Result judgment:
◆Calculation and Judgment:
Elastic recovery rate (elastic loss rate or compression ratio) = (T1-T2)/T1*100%. Among them, T1 is the original thickness of the test piece, and T2 is the pressed thickness of the test piece).
The compression of the insole is ﹤45%.
