JB-300B/500B Used Impact Testing Machine for Metal/ Lowest price impact testing equipment

JB-300B/500B Semiautomatic ImpactTesting Machine

Main functions

The machine can be used for the determination of anti-impact performance of metal materials when it is under dynamic loading, thus judged the quality of materials under dynamic loading. It is applicable for the laboratory, which does continuous compact tests, metallurgy, machinery manufacturing, and other industries.

Product features
The machine with the semi-automatic control, operates easily and efficiently. It uses the electric control the knife of impact to raise, impact and fall. Moreover, the machine can use the remaining energy to raise and fall to prepare the next test automatically after thrusting specimens.
