EKD heavy buffer was tested in a third party laboratory with excellent results! 
The test results show that EI series shock absorber have a high matching degree with the simulation data (higher than 90%), also have stable damping force output, high energy efficiency ratio, and can play a good impact absorption and safety stop.
