How Does the Bottle Cap Torque Tester Work?

How Does the Bottle Cap Torque Tester Work

Loose or stripped caps are a major source of concern in today's manufacturing operations, as they have a direct impact on product freshness, stability, shelf life, and possible leakage. Because moisture-sensitive or pressured materials require the integrity of the container lid and seal to be maintained, stability is of special relevance. Due to the loss of nitrogen in non-carbonated drinks, loose/stripped lids can cause both packaging and product concerns. Thus, it is important to maintain the integrity of bottle caps by testing with Presto bottle cap torque tester digital model. This testing instrument is highly useful in studying the efficiency of the bottle caps in the PET industries.

Here we will discuss the use of torque tester for bottle caps and how this lab testing equipment will serve to be useful in testing the torque value for opening the closed bottle caps. So, let us get started!

Use of torque tester for bottle caps in PET bottle industry

We all have opened and closed bottle caps tens of thousands of times during our lives. We have a broad concept of when a cap is correctly adjusted and when it is too tight or too loose based on our experiences. When it comes to judging how tight their caps should be, many manufacturers depend on their instincts. If your caps appear to be properly tight and you haven't had any problems with leaky bottles, you may normally continue to cap your bottles using an intuitive technique.

Thus, with Presto Bottle cap torque tester you will be able to measure the torque needed to open a closed bottle cap. Torque testing of PET bottles is considered to be an important aspect of package material inspection. Our torque testing machine will help you to eliminate the problem of manual torque testing of PET bottles.

Now, let us focus on the features and technical specifications of this lab testing instrument.

Features of Presto torque tester 

Presto offered sophisticated and user-friendly testing equipment that has been meant especially for the PET bottle industry to test the torque needed to open a closed bottle. This testing equipment gives a digital readout both clockwise (for closure closing) and in the anti-clockwise direction (for closure opening). The unique self-adjusting holding mechanism embedded in this testing instrument can easily accommodate any shape and size of the bottle with zero slip guaranteed.

Below we have created a list of its unique features:

  • The instrument is automatically restored to the initial position after testing.
  • The device is equipped with an inbuilt calibration mechanism.
  • The device is fitted with a highly accurate digital display for easy readout of testing results.
  • Strong clamping pegs/holders for zero slip gripping support
  • Digital Display for accuracy and repeatability
  • Precise measurement of torque
  • Height adjustable clamping mechanism to hold the different sizes of bottles
  • 9 Sample readings can be seen on the digital readout
  • Auto-Stop Function enabled
  • Motorized feature for high repeatability
  • Data output in digital display form
  • Machine to stop at an angle of 90º to avoid load on torque sensor
  • Servomotor Driven Mechanism
  • Adjustable fixture to test different size test bottles

With these features and technical specifications, you will be able to conduct the test accurately. By testing the torque of the bottle caps, you will be able to improve the quality of PET bottles. Now, let’s focus on the working of the Presto torque tester digital model.

Working of Presto torque tester digital model

The torque tester digital model is a very efficient laboratory testing instrument that may be used to conduct torque tests on caps and closures. By following the procedures below, you may simply use this lab testing equipment accurately.

  • To operate the Presto torque tester efficiently, turn it ON & connect it into 3 Pin - 5 Amp outlets. When you power on the equipment, the load indicator may display certain data based on previous test values.
  • In the next step, you can set the pressure to zero by pressing the TARE button and then the RESET button. After that, the load indicator will show zero readings.
  • Adjust the specimen holding pegs according to the size of the specimen and place the specimen accurately that will be straight and touch all four pegs at a given interval of time.
  • After you place the specimen accurately, then you need to tighten the jaw adjusting knob and revolve the specimen in the clockwise direction. When you perform all these settings, then you can easily commence the test.

In this way, you can easily operate the Presto torque tester for bottles. We are considered to be the leading torque tester manufacturer in IndiaYou can give us a call at +919210903903 or email us at to know about torque tester priceYou can even book a FREE online demo with our experts regarding the usage of this testing equipment.
