Testing Tiny Springs

Our client has a need to test tiny springs, the size of your thumbnail, but there are no testing devices on the market that are either small enough or fast enough to do so. Some of their current springs work great and others fail, and they need to know why- and how to check the springs they receive to know which ones will fail prior to installing them. We need to stretch this tiny spring, hold it in a stretched position, and un-stretch it all in less than the average blink of an eye. Our device is created to stretch these springs exactly 0.069" in 10ms, hold it stretched for 50ms, and un-stretch it in another 10ms. The average human blink is 100ms. Repeat this cycle 1000 times, taking pictures every 250 cycles, to see changes in the metal and know where it fails.
