PET bottle cap torque test

Mecmesin, through their Portugeuse supplier Egitron, presented us with a good solution: reliable equipment and user-friendliness that was adequate for our needs. All our operators are capable of using the equipment because it is very simple to operate. I enjoy dealing with Egitron because they offer excellent technical support.

Requirement

For over a century, Agua de Luso has been one of Portugal's most famous names in mineral water.

Agua de Luso's mineral water is packaged in a variety of sizes of plastic (PET) bottles and it is essential that the caps on their bottles are easy to open, while at the same time applied tightly enough to ensure the bottles do not leak.

To guarantee the quality of their packaging Agua de Luso wanted to test the slip torque and bridge torque on their tamper-evident bottle caps.

They acquired five Mecmesin Tornado digital torque testers to precisely quantify the torque applied to the bottle caps. The easy-to-use 10 N.m capacity Tornados have proven to a be a good choice for Agua de Luso.

Solution

To ensure quality and consistency, Agua de Luso tests its bottles for compliance with company standards. At routine intervals, operators at the bottling plant in Luso place filled bottles onto the Tornado digital torque tester and the cap is tested for ease of opening and tightness of seal.

Before Agua de Luso purchased the Tornados, torque testing of bottle caps was performed using a less accurate analogue gauge-based manual testing device.

The Tornado's digital torque capture technology combined with clear intuitive controls, easy-to-read pass/fail parameters, and an onboard memory to keep statistical results offers far greater accuracy and ease of use.

Agua do Luso commends the Mecmesin Tornado digital torque tester for its accuracy, portability, and simplicity of use, and praises the technical support and efficient calibration service provided by Mecmesin's distributor in Portugal, Egitron.

For Agua de Luso the rewards of the Tornado closure torque testers are obvious: ensuring customer satisfaction with cap openability while retaining the integrity of their packaging and avoiding quality related problems.

OrbisCap torque tester

Basic
Orbis

The Orbis digital torque tester is ideally suited for basic clockwise and counter-clockwise torque tests.

Manually operated and measuring up to 6 N.m its capacity is ideal for most caps and closures which are intended to be opened by hand.

Providing data with significantly greater accuracy than analogue torque devices, it’s a simple and cost-effective solution for a variety of torque applications.

Advanced
Tornado

The Tornado digital torque tester is ideally suited for the testing of application and removal torque on caps and closures.

Manually operated, the Tornado range has 4 models with capacities ranging from 1.5 - 10 N.m to cover almost all closures types and sizes.

Its ability to detect initial bridge torque and peak torque make it the instrument of choice for testing closures with tamper-evident seals.

Clean-room
CAPTEST

The CapTest digital torque tester is ideally suited for basic clockwise and counter-clockwise torque tests where the testing environment calls for greater protection.

Manually operated and measuring up to 5 N.m, its stainless-steel housing lends itself for testing caps and closures in medical & pharmaceutical clean-rooms and production areas where the risk of liquid splash is high.
