The “Enhanced” Opening Force Gauge from Torus Measurement Systems builds on the success of the standard model used by leading end makers.


By monitoring critical manufacturing parameters over time and relating the press performance to the change in the ends opening signature, the manufacturing process capability can be observed. This trend monitoring is extremely beneficial to the process engineer, in predicting potential out-of-spec score residual and other critical features. By sampling ends from the production line, the Opening Force Gauge can monitor tooling wear in real-time and provide significant savings in both labour and scrap.
