Today I will show you a piece of small testing equipment from Zebung Testing Laboratory. The machine that Zebung's technical engineers are operating is a roller abrasion machine used to measure the wear resistance of rubber. This machine passes the test and the rubber material Under a certain load, it is rubbed against the gauze on the roller, and the wear amount of the test sample within the specified stroke is measured to determine the wear resistance of the rubber compound. Each batch of rubber samples produced by Zebung will pass the inspection of relevant machines.
