Understanding Impact Testing machine Ecosystem

A Charpy Pendulum Impact Testing machine mainly consists of a high-stiffness main frame, pendulum impact system, precision measurement and control system, safety protection device and specimen handling system. HST JBS-450C is an integrated high-performance solution, not just a single component. It combines a one-body cast frame, high-precision optical encoder, Panasonic PLC control, full-closed safety cover and automatic specimen recovery system to ensure stable, accurate and safe Charpy impact test results.
