Mecmesin announces ‘Helixa’ precision torque tester

New from Mecmesin, the Helixa precision torque tester has been designed for achieving precise alignment when using the most sensitive torque sensors. It is a significant development in the torque testing of medical devices.

Designers and engineers of the smallest rotary controls, the lightest springs, the finest bearings, and the most precise rotating connectors are already adopting the Helixa for its leading-edge features.

A choice of intelligent torque cells allows measurement from 6 N.m down to just a few mN.m. Concentricity at extreme low torques is ensured by the facility to align specific fixtures with the selected torque cell. Mecmesin’s Emperor™ control and acquisition software provides for building sophisticated test programs and complex results analysis. This combination of features ensures an unparalleled degree of accuracy and repeatability.

The Helixa is ideal where rotation of components is very precise, or very light, measuring a range of critical torque features, the precise operation of dosage control dials as in injector pens, the 360 degree smoothness of controls, or the quality assurance of mass-produced medical Luer slip and lock fittings.

Where axial forces count, the Helixa has additional key features. A counterbalancing mechanism can be used to remove axial forces due to the torque cell and fixturing, and if required, a top-load platen can then be used to apply a specific static axial force.

Applications for which the Helixa has been designed include:

  • Luer fittings (slip and lock)
  • Dosage-dial drug delivery devices (e.g. insulin pens)
  • Light and miniature torsion springs
  • Electronics rotary controls and components
  • Fine and high-performance bearings
  • Child-resistant closures (CRCs)

Mecmesin Managing Director John Page states:

“With the release of the Helixa, Mecmesin now has the ability more effectively to address low torque applications (below 6 N.m) where the accuracy and repeatability of results is crucial. The counterbalanced crosshead means that the frictional effect on the sample from the mass of the transducer head during testing is significantly reduced. Combined with the ability to align and lock the position of the transducer concentrically in relation to the lower fixturing it ensures the Helixa will provide market-leading reproducibility of test data.”

The Helixa is available as a PC-controlled version (the Helixa-i), driven by Mecmesin’s powerful Emperor™ software, or as a stand-alone version (the Helixa-xt) controlled from an integral touch-screen console.

Complementing the Helixa is a range of torque testing accessories, including a precision fixing plate for securing even the lightest samples and bellows for dust protection. Mecmesin has a team of experienced application engineers to design bespoke fixturing often required for precision testing at this level.

Mecmesin OmniTest machine demo by the Duchess of Sussex at University of Chichester Tech Park opening

The Duke and Duchess of Sussex officially opened the University of Chichester’s new Engineering and Digital Technology Park on 3rd October 2018. Part of the tour of the £35million development, based at the Bognor Regis campus, was a visit to the Department of Engineering and Design. The laboratory features several Mecmesin force measurement machines, notably a 50 kN OmniTest Universal Testing Machine (UTM); a state-of-the-art software-controlled materials testing system.

Methods of force and torque testing for food packaging quality

Packaging solutions for food are incredibly diverse; in all aspects of physical design, mechanical function and aesthetic appeal. Their purpose is more straightforward: be safe, secure, yet easy to open, close or reliably re-seal; dispense cleanly and efficiently; minimise loss and waste; maximise shelf life; be cost-effective to manufacture and ultimately recycle or dispose of. Add to that, the consumer desire for attractive and innovative new designs, and the straightforward ultimate purpose can become quite involved in terms of meeting each individual challenge.

Mecmesin white paper: Force testing in medical tubing

Plastic medical tubing is central to the provision of effective health care in the 21st century. It is essential for the delivery of blood, nutrients and gases to the patient, and for the execution of minimally invasive surgical procedures such as cardiac angioplasty, which have proliferated widely over recent years. This article examines four force testing procedures for plastic medical tubing and explores the benefits and methodological considerations of each.

Universal testing machine range (0.5 - 5 kN)

Mecmesin offers a wide range of universal testing machines (UTM) for tension and compression testing. At the top end, our MultiTest-i systems are driven by the powerful Emperor™ control and analysis software on a separate PC, while our production-level testers in the MultiTest-xt series offer touch-screen ease of use and rapid processing. All of these systems give fully programmed control and accurate, repeatable testing, with test libraries for instant recall.
