This series of impact testing machines is a semi-automatic control testing machine. The swing, impact, and placement are controlled by electrical appliances. It can use the remaining energy after breaking the sample to automatically raise the swing to prepare for the next test. It is especially suitable for laboratories that conduct continuous impact tests and metallurgy, machinery manufacturing and other industries that conduct a large number of impact tests.It complies with the national standard GB/T3808-2002 "Inspection of Pendulum Impact Testing Machine" and conducts impact tests on metal materials according to the national standard GB/T229-2007 "Charpy Pendulum Impact Test Method for Metallic Materials".It is used to measure the impact resistance performance of metal materials under dynamic loads, thereby judging the quality of materials under dynamic loads.
