Wine cork extraction test to ISO 9727-5

  • Mecmesin

The customer, AMORIM & IRMÃOS, S.A – Unidade Industrial da Valada, required an economic and easy-to-use system to test the extraction force of corks from glass wine bottles. The test specifies a speed of 300 mm/min according to ISO 9727 and the corkscrew should be applied to a depth of minimum 3 mm below the base of the cork.

Solution

A corkscrew with a ‘loop handle' was used so that it could be placed easily in a fixed test hook. The corkscrew was first screwed into the cork by the operator ready for loading onto the hook. The bottle was then held down to the base plate of the test stand by a collar mechanism, positioned over the neck of the bottle.

The collar mechanism was made freely adjustable on two rods to allow testing of bottles of varying heights. The peak tension-force to extract the cork was then recorded on the gauge.

Test equipment

Motorised test stand
Force gauge or data acquisition software
Cork Screw fixture
Adjustable bottle holder fixture

Test standards: ISO 9727-5 Cylindrical cork stoppers - Physical tests - Part 5: Determination of extraction force

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.
