New Test Equipment Factory, Jinan China specializes in the production and supporting a variety of impact test machine. The main products are: manual impact testing machine, semi-automatic pendulum impact test machines, automatic pendulum impact test machines, automatic temperature impact testing machine, impact notch manual / electric broaching machine, projector notch impact test, impact test cold ducts. 
 JB-300B pendulum impact testing machine used for the determination of metallic materials to resist the impact of the dynamic performance under load, in order to determine material quality under dynamic load conditions. 
 JB-300B is the company strictly in accordance with national standard GB/T3808-2002 "pendulum impact testing machines," design and production, according to national standard GB/T229-1994 "metal Charpy notched impact test method" impact test of metallic materials. Maximum impact energy of 300J, and 150J with a pendulum, the cross section of samples was 10 × 10mm, mainly on the impact toughness of the larger black metal, especially steel and steel alloys tested. 
 The machine is semi-automatic control, simple operation, high efficiency, Yang pendulum, impact, put put electrical control, and can use residual thrust energy of the sample automatically after the next test well placed for Yang, in particular, do impact test for continuous laboratory and do a lot of impact test of metallurgy, machinery manufacturing and other industries.
