Wireless torque bottle

To control the quality of tightening of closures in production, most of the time, the loosening torque on the bottles is measured after the closure has been screwed or pushed in by the capping machine. The results obtained are often very difficult to correlate with the actual applied torque during screwing for several reasons:

• The storage conditions of the bottle can impact the torque. For example, if the bottle is subjected to heat or cold, the materials will shrink or expand. These variations change the release torque.
• The unscrewing torque, if measured manually, can vary according to the operator, the speed of rotation, the force exerted on the cap...
• With the unscrewing control a maximum torque value is obtained but it is not possible to see what happens during rotation and locking.

To solve all these problems, Andilog has developed a wireless torque sensor that we integrate into bottles to directly measure the torque in production or during development.
