SATRA remains open during the coronavirus COVID-19 pandemic and has organised additional online resources and a special webinar programme
SATRA STM 477F Bally vamp flexer (12 station)
Flexing tests are sometimes required to be carried out at low temperatures. This determines the suitability of materials being tested to flex at temperatures below 0°C. SATRA provides a range of these machines and uses a low temperature cabinet specifically designed to suit the test.
The SATRA low temperature cabinet ensures maximum operator safety by having the electrical control and drive systems outside the freezer area where moisture cannot impair electrical safety. The control system incorporates a digital temperature controller which can be set to achieve the desired temperature from ambient down to -20°C, plus a counter to indicate the number of flexes carried out. The counter can be preset to stop the drive mechanism when completed.
This machine is the same as the STM 408F but has 12 stations. It is normally specified when a higher volume of testing is demanded.
