Dan , we used similar torque gages down at the soap plant for setting our capper chucks for the lids . We preset them according to bottle size back in the shop area . Once the capper set the cap , it tightened to the set torque on the chuck and popped open . We later went to rare earth magnet chucks that could be set easily while on the machine itself , with the clutch slipping at the needed torque . One of the biggest complaints from consumers were either they couldn't get the caps off , or there bottle leaked when turned on the side . Our biggest complaint was about the inconsistency of the bottle blowing plant . Tide ( P&G) , had a different sealing method than Unilever , there's being a great big flat rigid surface , ours sealing on a small taper .
