What is the easiest method to perform a torque test on PET bottles?

PET bottles are sealed with caps or closures to ensure product safety and prevent leakage. Torque testing assesses the integrity of the cap seal by measuring the tightness or looseness of the closure. Proper torque ensures that the cap is securely fastened, minimizing the risk of leaks, contamination, or tampering. Presto Torque Tester- HMI Motorized is one of the high-quality lab testing instruments that is used to test the torque strength of packaging materials and ensure that quality products will be delivered to the customers.

Working procedure of Presto torque tester :-

To conduct a torque test using the Presto torque tester HMI motorized model, you can easily follow the steps mentioned below.

• Plug in the mains plug into a 3 Pin - 5 Amp power socket. Turn the machine ON.
• Rotate the jaw-adjusting knob in the anticlockwise direction to take the jaws apart.
• Place the sample of the bottle to be tested on the test platform.
• Adjust the specimen holding pegs according to the size of the specimen.
• Place the specimen properly in such a way that it is perfectly straight and touches all four pegs at a given time.
• After placing the specimen, tighten the jaw-adjusting knob properly by revolving it in a clockwise direction.
• Place the upper closure on the bottle sample and adjust it according to the height of the sample and tighten the knob appropriately.
• The Load display might show some readings due to previous test values.
• Once all the above steps will be performed, you can easily commence the test.



By following these steps, one can accurately conduct torque tests on PET bottles and ensure that the quality of materials will be delivered to the customers. Give us a call at +91-9210 903 903 or email us at [email protected] to get a live testing session for this testing instrument for free.
