The bjjb-300b semi-automatic impact testing machine is used to determine the performance of metal materials under dynamic load, so as to judge the quality of materials under dynamic load.

This machine is semi-automatic control testing machine, the operation is simple and high efficiency, Yang pendulum is, impact, control, and can use the surplus energy of thrust sample after automatic Yang place ready for the next test, especially for continuous do impact test impact test lab and a lot of metallurgy, machinery manufacturing and other industries.

The bjjb-300b impact testing machine is in conformity with GB/ t3808-2002 "test of pendulum impact testing machine", and the impact test of metal materials is carried out according to GB/ t229-2007 "metal materials charpy impact test method".
