The dynamic beverage bottling industry continues to evolve and solutions to cap torque testing have done the same.
- Lightweight bottle/cap.
- Retaining pressurization for providing rigidity. Collapsing bottles/pallets.
- Lightweight caps can be sensitive to gripping pressure.
- Sport cap, short cap, 1-piece cap.
- CO2 pressurized products.
- Retaining pressurization (CO2), operator safety (high pressure).
- 1-piece cap.
- Hot products.
- Cap and bottle are different thermoplastics, shrinking at different rates. Operator safety associated with handling hot products.
- Some have induction seal.
- Sport cap, 1-piece cap.
Release Torque Testing
Description: With a highly sensitive strain gage-based torque transducer, a 2000 CPR rotary encoder and proprietary pressure controlled cap and bottle gripper designs, our servo-driven automated torque tester can accurately detect both small and large changes in the torque and angle during the removal of a closure.
TEB (Tamper Evident Band)
Description: When tamper evident caps are used just knowing the release torque is not always enough, often knowing the torque required to break the bands is desired. Using a rotation driven release both the thread break and the band break can be measured. (See pg. 45 of ST-120S operator manual for info on how to set this up).
Description: With the ability to deliver and measure up to 88 lbf.in (10 Nm) of torque, we can find and report the torque it takes to strip out the threads when tightening your containers closure.
Description: Used to tighten a cap to a precise torque. Not often used by itself, aside from an evaluation or validation of a capping process, it can also be combined with the release testing for nondestructive testing as well as fatigue and accelerated aging testing.
