This tester is the steel ball falling in soft foam plastic or other flexible material sample, measuring instruments, the height of the rebound in the test project is mainly used for the determination of polyester elastic material because of the elastic energy in the coefficient of restitution. By microcomputer and photoelectric technology, electromagnetic control, digital tube display directly back to the weak coefficient values.

This machine is used for testing the rubber ,foam static compression ,put it between the tablet,use the screw to fix.When the ovenware up to suitable temperature,Compress rubber and put it on

is used to determine the rebound-character of the specimen of rubber product, which endures a certain compression force under the specified time period. Put the specimen onto the test pan leverlly and grip it between two compression plates. Through the specified time period, take it out and cool it down then measure its center thickness to get its rebound rate.
