1. Application:
JBDW-C type impact testing machine is used for measuring the metal material resistance performance under dynamic load, in order to determine the material properties under dynamic load. It's a necessary testing machine, not only used in the metallurgy, machine manufacture etc areas, but also used for the science research.| Model | JBDW-300C | JBDW-500C | ||
