STM5 Shock Test Machine


The STM5 has been developed to meet the shock testing requirements of the small
components industry. Several machines have been delivered to watch manufacturers in the
field of production quality control together with research and development. Test items are
mounted on a 150mm cube which allows for testing multiple components to be tested in
three axis.This machine is unique in our product line in having a dynamically tuned beam
pivoting at one end, this construction allows resonant free testing down to at least 0.3ms.
Beam lifting is achieved by a built in pneumatic ram which is then accelerated down
allowing the beam to free fall. Through utilisation of timer counters coupled to high precision
valves controlled by our IMPALA software, this machine generates highly repeatable
shocks at a rate of up to ~60/minute.
