Torque Testers in the Chemical Industry

Many chemical products are sold in spray bottles which must withstand corrosive chemicals. These bottles often use a trigger handle for dispersion, which can produce interesting torque challenges. The unique combinations of bottle and cap in the chemical industry may consist of push and turn, dispensing, snap top, child resistant, or squeeze and turn closures.

Mesa’s universal tooling approach offers solutions for all of these combinations. Our torque testers are also built to withstand corrosive chemicals that may come in contact with the tester, and are capable and built to handle oversized, uniquely shaped bottles.

To learn more about which Mesa Torque Tester is right for your chemical products, contact our office and request to speak with some of our torque product specialists.

Challenges

Spray bottle and other unique bottle/cap combinations can make torque verification and analysis a challenging proposition for this industry, but Mesa’s universal tooling approach offers solutions for these unique situations. Our Torque testers built to withstand corrosive chemicals which may come in contact with the tester. Mesa’s testers are also capable and built to handle oversized, and uniquely shaped bottles, which are prevalent in the chemical industry.

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.

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).

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.

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.

Testing the Seal Integrity of Pouches and Eye Drop Bottles

It has been determined that release torque testing is not an appropriate way to test the seal integrity (tightness) of pouch caps or eye drop bottles. The problem with release torque testing is that these caps have integrated tamper evident bands and the tamper evident bridge break torque cannot be reliably and easily distinguished from the thread break torque of the cap.

Due to this design, there is a major concern with using the release torque as an indication of seal integrity. It can be difficult to differentiate between the thread break and the bridge break peaks. Also, it is possible to rotate the cap on the bottle neck to a point where the TEB is properly engaged but the threads are not tight, and the bottle is not sealed.

If the TEB break torque of a loose cap falls in the acceptable removal torque range of a normal cap, it is impossible to differentiate between the release torque result of a tight cap and the TEB bridge break torque of a loose cap.

To overcome this issue, Mesa has implemented a new test method, one that tightens the closure and measures the rotation of the cap from the cycle start until the application setpoint is measured, instead of measuring removal. The more the cap is rotating, the looser the cap.

Using the Torqo 1600, you may use the “close measure mode” to replace the release torque test for seal integrity testing. The close measure mode is designed to measure the torque which is applied to a cap.

The system will rotate the cap in the clockwise (closing) direction until the cap begins to rotate. The point at which the cap begins to rotate will be considered the application torque and will be displayed on the screen.

Another cool aspect of the newest generation of Mesa’s Torque testers is the interchangeable tooling, that allows the end user to perform torque tests on multiple different types of packaging.

How to Properly Calibrate Your Torque Analyzer

 

Cap torque analyzers are an extremely refined set of products that need to be cared for and calibrated on a regular basis to ensure accurate and consistent results. Calibrating these complex machines can be an intimidating process, however there are tried and true steps to follow to improve not only the calibration process, but also the end results.

Why is calibration important?

Regular calibration ensures that you’re getting the most accurate results which can greatly improve your ROI and avoid production loss and costly recalls. We recommend calibration be performed at least every 12 months.

 

The Five steps to calibrate your torque machine include:

  1. Before beginning calibration, be sure to attach the frame with 1-2 screws to ensure stability.
  2. Insert the pulley into the chuck and rotate the chuck. Make sure the screw is facing a direction that allows the wire to twist 90 degrees and lock the shaft.
  3. “Zero out” any offset and hang the weight slowly and deliberately.
  4. Make sure the weights are still and are not touching anything.
  5. Be sure to calibrate both sides of the machine. This will give you the proper torque read out.

 

To make sure you are consistently getting the most accurate results from your SureTorque products, Mesa Labs recommends yearly calibrations.

To meet your needs, we currently offer 3 different ways to manage your calibration:

  1. On-site calibrations
  2. Send your lab equipment to us
  3. Laboratory calibration kit

Call our offices now to inquire about Mesa’s calibration services.

Bottle Cap Torque Testing: Why is it Important?

Over time, the subjective feeling of cap tightness triggered the development of more reliable and consistent measurement devices, such as the spring based manual torque tester (analog). By the late 1980’s, ergonomic concerns and repeatability issues (such as varying cap gripping pressure and employee joint/muscle issues) lead to the development of manual (digital) and automated torque testers. Ever since, changes in materials, marketing themes, transportation methods and packaging aesthetics and processes (induction sealing, hot filling) have created new challenges and drives continuous product improvement on this field.

 

Why is Cap Torque Important?

Consumers judge bottled product quality based on many observations:

  1. The appearance of the package.
  2. The appearance, efficacy/taste of the product.
  3. The ease of opening and re-sealing the closure.

 

Brand owners, bottle cap/bottle suppliers are under tremendous pressure. They must:

  1. Reduce the cost of the packaging (lightweight, 1 vs 2 piece enclosures). – Lightweight bottles are pressurized to maintain product quality and package integrity. Insufficient torque and a resulting bad seal can reduce shelf life, cause product leaks, and the bottles can collapse when stacked in multiple rows. – Lightweight caps are more sensitive to over-torqueing. Over-torqued caps can develop cracks causing product spills and shelf life issues.
  2. Improve the shelf-life of the products (hot-filling, induction sealing). – The different thermal expansion contraction rates of the cap, liner and bottle materials, the varying dwell times between cap tightening and release torque measurements can all result in different release torque values. – Too much torque can cause wrinkles on the foil resulting in a bad seal, spills and reduced shelf life. If the threads strip, or the applied torque is too low, the foil will not be seated properly resulting in shorter shelf life.
  3. Maintain the quality of the product while innovating package design, improving aesthetics, ergonomics and security (tamper evident band, child-resistant design).

– Example: User configurable cap that can function both as Child-Resistant (CR) and nonCR closure. Such design increases QC requirements:

The torque must be monitored to maintain good induction seals.

The CR functionality (shelling/reverse ratchet/topload) needs to be controlled.

 

We have some tooling and machinery available for onsite demos. For more information or to schedule a visit please call 800-829-5741.
