In the packaging industry, screwing is a crucial stage. Yet it remains a frequent source of quality problems: sealing, transport, contamination, and much more. In response to these challenges, ACRN has designed the Repeatork, an innovative motorised torque meter that meets the quality, maintenance and production needs of manufacturers.

Find out why Repeatork is the ideal solution for guaranteeing the reliability and conformity of your products.

1. The challenges of screwdriving in industry

In sectors such as food processing, cosmetics and pharmaceuticals, screw fastening is ubiquitous. Despite technological advances, it remains a source of numerous quality concerns, such as :

  • Leaks or sealing problems that jeopardise product safety.
  • Unscrewing during transport or use by the consumer.
  • Product contamination due to faulty closures.
  • Difficulties in opening, which frustrates the end user.

Why do these problems arise?

They are often the result of insufficient, excessive or irregular screwing, or of defects in the materials used for caps or containers. To avoid these costly errors, post-production quality control is essential.

2. Why check the tightening and loosening torque?

The unscrewing torque test enables the conformity of a product to be checked quickly and accurately by measuring the force required to open a cap and ensuring that this is within predefined thresholds. However, traditional methods have a number of limitations.

Manual torquemeters are influenced by the human operator, which can lead to rough handling or irregular speed, compromising test accuracy. In addition, a poor grip on the cap can cause it to ovalise, altering the results. These limitations often lead to poorly reproducible measurements, raising doubts about the reliability of the tests carried out.
