                  It is used to test extend and stretch capacity of metal thin plate and band and also is the only instrument to test the metals plastic deformation[...]
                  It uses a cycle mixing method following heat balance principle to automatically and equably cooling sample and keep temperature.[...]
                  The machine contrast the impact sample U type gap or V type gap to standard map and judge if the sample is eligible.[...]
