Cap suppliers specify the draw height of the caps they supply. In order to meet the specifications, the cap draw height must be measured. It is difficult to measure the cap draw height with a vernier, often producing different measurements and different results.
In cooperation with a cap supplier in Australia, the Cap Digital Redraw Gauge was developed by SI Instruments Non Destructive Testing . Users need to push the foot of the gauge on the cap and the indicator shows the draw depth. This ensures the cap draw height can be measured correctly, quickly and easily.
