Digital Torque Testers - .PDF file.

German manufacturer Pfeiffer is using the Tornado digital torque tester from Mecmesin on pump dispensers to check seal quality.

Pfeiffer wanted to quantify the correct level of torque required to seal pump dispensers, commonly used within its dosing systems and atomisers in the pharmaceutical and cosmetics industries.

It was critical to gain accurate data to prevent incorrect settings being applied on the production line, as this would result in the poor performance of the pump dispenser and the possible leakage of the container contents.

The Tornado digital torque tester is used to check the application and release torque of closures.

A typical test involves a container sample held securely by four gripping pegs, enabling the manual application of torque between 0.8Nm and 0.85Nm.

Upon completion of the test, seal tightness is verified and the correct torque application is determined.

Christoph Szymiczek, manager of technical service at Aptar Pharma, said: ‘We perform a variety of tests on our pump products, one of which is to evaluate their release torque.

‘In order to precisely apply torque to screw and unscrew the pumps, we use Mecmesin equipment,’ he added.

The Tornado is described as a simple and effective digital torque tester, providing consistent high-accuracy results.

An MK2 model supersedes the MK1 tester that Pfeiffer uses, offering even greater versatility.

Available in four capacities, 1.5Nm, 3Nm, 6Nm and 10Nm, this manual torque tester records up to 500 readings, tests tamper-evident closures and enables results to be exported to peripheral devices such as printers for further analysis.

A leading force and torque measurement specialist for over 40 years, Mecmesin designs and manufactures affordable, reliable and accurate test measurement equipment to suit a wide range of applications and customer requirements.

Quality Standards
Mecmesin’s range of test equipment is an affordable way to measure force and torque to BS, DIN, ASTM and ISO standards.

Operating under ISO 9001 quality standards, Mecmesin force and torque testers are used to guarantee the quality of components, materials and finished products, direct from the production line or within a QC laboratory. These checks help businesses maximise production and conform to international or in-house standards, whilst reducing the costs associated with excess wastage.

From simple hand-held instruments to fully-comprehensive computer-controlled test systems, Mecmesin designs products to suit many different test applications and budgets.

Force Test Systems
Mecmesin’s force test systems provide machine control of tension and compression testing plus many other test types via the addition of appropriate fixtures, such as flexure/bend, peel, pull-off/pull-out and top-load/crush resistance. A choice of load ratings, including high capacity up to 50 kN, and a range of physical dimensions cater for a broad spectrum of force testing applications.

Torque Test Systems
Mecmesin’s torque test systems provide machine control of the testing methods for all types of torque – breakaway, fastening, running and torque to turn. The ability to simultaneously apply an axial load to the sample is available on all systems. A choice of load ratings cater for a broad spectrum of torque testing applications, with the addition of a range of high precision systems suitable for measuring very low torque values and running with exact rotational alignment.

Application-specific Testers
Mecmesin also supplies a range of application-specific testers, designed to test to test to international standards for a diverse range of distinct test applications, such as coefficient of friction, pull testing of cables, page pull strength of books, automated bottle testing, testing muscle strength and testing sprayed concrete.

Force and Torque Instruments
Mecmesin’s manual force and torque instruments provide digital accuracy in test measurement combined with affordability and portability. Three digital hand-held gauges are available with convenient levels of functionality and ranges of capacity. These gauges can be paired with manual lever or wheel-operated test stands to perform basic tension and compression tests with increased repeatability.

Mecmesin’s range of manual, hand-operated torque testers enable the testing of rotational systems including container caps and tamper-evident closures.

Gripping a sample correctly for testing is a fundamental aspect of test repeatability.  Mecmesin supplies a full range of grips and fixtures for use with all our test systems and instruments.

In addition to our standard products, Mecmesin application engineers can design and manufacture test solutions to meet the needs of unique applications with specific criteria.  These typically include vacuum fixtures for preform packaging, cap mandrels to fit specific designs, grips for control devices with moving parts, jigs for bending awkward or large items, fixtures for torsion springs, guards and containment, and many more…
