What force is required to remove a DVD from its box?

The customer, a leading supplier of boxed DVD’s, had experienced a wide variation in the amount of force required to remove the DVD from the central spigot of the case. In extreme cases, this resulted in damage to the actual disc.

The customer needed to test the removal force of the DVD to ensure consistency in their manufacture, whilst enabling end-users to easily detach the DVD from its packaging.


A 1000 N capacity MultiTest-i computer-controlled test system was provided by Mecmesin, combined with a 250N intelligent loadcell (ILC), compression probe and case support fixture.

To carry out a repeatable removal force test method, measuring the release force of the DVD media from its dedicated plastic casing, the central spigot is placed directly under the loadcell.

The loadcell is then driven down at a constant speed until a load reading is detected, signifying the DVD has moved and the release process has started. The load, at this point, is then recorded and saved as the test result.

The MultiTest-i test frame offers excellent accuracy and the ability to view results graphically, enabling the company to clearly identify the release force in every test.

Cosmetic packaging pull-off test

A bench-top testing system was required to repeatably test the pull-off force on a variety of cosmetic containers. The system needed to allow a relatively high volume of containers to be tested with the minimum level of training required for users. Mecmesin's solution avoided the risk of damaging the loadcell by excessive torque on tightening the collet grip, and the lipstick barrel was first inserted in the grip and then connected to the gauge by a flexible chain-link.

Food packaging made from thermoformed plastics and intended for freezing, requires testing to ensure optimum functionality when closing and sealing the container. The closing effort of the lid is measured by using a motorised force tester controlled by software together with a custom-designed fixture to hold standard-sized ice cream tubs. In addition the ‘top-load’ crush strength of the container itself can also be tested on the same machine to guarantee it is rigid enough to avoid buckling and spillage when the lid is applied.

Mecmesin develops Combi Cork-i Extraction Tester for leading Scottish whisky

To improve the quality and storage of a premium product, the R&D team at a leading Scottish whisky maker needed to optimise the design of their bottle stoppers. They decided that the strength and performance of their reusable stoppers could be ensured by systematic testing of the characteristics of both portions of the stoppers. Working closely with the R&D team, Mecmesin developed the Combi Cork-i Extraction Tester, an innovative multi-function cork extraction testing system that tests both phases of de-corking synchronously.

Greek beauty product manufacturer guarantees production quality by updating to Mecmesin's digital torque testers

A manufacturer of a wide range of skin, hair-care, make-up and sun-care products based in Greece needed to replace their outdated torque testers with up-to-date digital torque testers to guarantee production quality and to ensure their products remained sealed. Mecmesin supplied the company with two Tornado 10N.m digital torque testers, which have the ability to test tamper-evident closures, an intrinsic part of their specification.
