Mandrel Peg Drive, 54 mm

This fixture is connected to the torque sensor of the Vortex or Helixa. It has 4 metal pegs with an internal opening of 54 mm into which the single-form mandrel can be positioned. The pegs drive the mandrel and thereby apply the tightening and release torque. Other sizes of Mandrel Peg Drive also available.

432-678 V-jaw vice clamp, four jaws with screw-action adjustment

V-jaw Vice Clamps have opposing V-shaped, serrated rubber-faced jaws. These securely grip samples made of smooth or low-friction materials, such as plastics. 432-678 features 4 jaws which are adjusted using a knob to position them equidistantly around the central axis. Both jaws are precisely adjusted around the central axis with a screw-action handle. 

432-677 V-jaw vice clamp, three jaws with quick lock and release lever

V-jaw Vice Clamps have opposing V-shaped, serrated rubber-faced jaws. These securely grip samples made of smooth or low-friction materials, such as plastics. 432-677 features 3 jaws where the single jaw features a quick lock/release lever to speed up testing of batches of the same sized container. The double jaw is precisely adjusted with a screw-action handle and the single jaw is locked and unlocked into place with a toggle-action lever.

V-jaw vice clamp for torque containers, screw adjustment for Orbis, Tornado, Vortex

PSV18221 (with screw action adjustment) is designed for torque applications. Stable clamping is achieved by two vertically-spaced jaws on one side, stacked above and below the single opposing jaw. The serrated rubber jaw faces make these accessories ideal for gripping low-friction specimen surfaces such as hard plastic or glass bottles.

V-jaw vice clamp, three jaws with quick lock and release lever for Orbis, Tornado, Vortex

PSV18155 (with toggle clamp for quick release) is designed for torque applications. Stable clamping is achieved by two vertically-spaced jaws on one side, stacked above and below the single opposing jaw. The serrated rubber jaw faces make these accessories ideal for gripping low-friction specimen surfaces such as hard plastic or glass bottles.

ISBT sports closure bite and tension tests

Custom fixtures are required to meet ISBT tension test standards

The pull force needed to separate the tear-off membrane base from the spout of the sports closure is measured using a custom fixture. This ISBT test measures the tensile strength of the assembled product.

ISBT sports closure rotational test

Close-up of the bite mechanism engaged with push-pull spout in the fully open position

The rotational force needed to remove the closure spout from a sports cap body is measured using the Steinfurth Rotation Tester for Sport Closures mounted on a Mecmesin tensile tester. This ISBT test simulates a person biting or pulling on the spout when attached to a PET preform and requires specific tensile test equipment to meet the standard.

Stelvin ROPP Wine Closure Removal Torque

An adjustable Stelvin® cap mandrel ensures optimum accuracy in torque measurement

The packaging of wine has great influence on the quality of the product delivered to the customer. Traditionally the method of closure has been the natural, or latterly synthetic, cork stopper. This solution, despite attaining high standards of sealing and taste preservation, can present problems for the end user attempting to remove the cork. As a result, the industry has developed alternative screw-cap designs aimed at achieving more consistent and reliable performance.

Custom closure mandrels

Plastic bottle caps and T-corks have individual profiles for finger gripping, and the best way to torque-test their performance is by providing an exact machine grip at as many points as possible. Many well-known brands and manufacturers come to us for custom-profiled mandrels to use on their torque testers. A custom mandrel is much quicker to place and release than a screw-fit clamp, and by precise positioning offers true repeatability in testing of bridge torque, removal torque, application torque and running torque.

Torque tester for dedicated TE caps

Quick change capability allows rapd testing of each cap design

Elopak required equipment for the manual testing of tamper-proof seals on bottle caps, but without the bottle being present. The unit had to accommodate a range of different size caps.
