Miniature Spring Performance Tester

In order to qualify miniature springs, manufacturers of these systems rely on commercially available testers that are designed for large-scale springs (>0.5" diameter). Commercially available spring test systems lack sufficient force resolution or cyclic test capabilities for miniature-scale springs. Traditional spring testers work on the basis of compressing (or extending) a spring to a known deflection and recording that force value, then moving to the second known deflection and recording that force value. This is done manually by a user and has no capability of automation or fatigue.
