As the standards of quality and reliability expected of manufacturers and suppliers continue to increase, it has become imperative for them to implement processes that ensure the efficiency and dependability of their production lines. Screw-tightening in particular is a very important part of the assembly process and it's crucial for every screw to be properly fastened according to its specification. Recorded historical data, thus, becomes a key component of quality management, as it gives companies the ability to audit components and track potential quality deviations in a speedy and cost-effective manner.


Why is Traceability important?

Traceability is the ability to trace the history, application or location of an entity by means of recorded identification. A traceability program provides the data needed to prevent, monitor and quickly correct quality issues in production processes, like fastening. Whether it relates to process validation, containment or audit requests, implementing a traceability system can reduce the time and resources needed to capture the data that various stakeholders are requesting.

With a traceability system, manufacturers can quickly detect production problems and inefficiencies. Simple enhancements—such as digital storage and access to documents, consolidating databases, simplifying expense and cost-recovery systems, and automating manual processes—can have a major impact on overall production costs.

For instance, if a recall event takes place, manufacturers are able to minimize their time and cost impact, as well as those of their customers, by only recalling affected items, i.e. the ones with serial numbers matching those that were assembled using the faulty component.


Traceability in the fastening  process

Transducerized intelligent assembly systems, like the K-DUCER from KOLVER, are able to gather, register and export the fastening data for quality control and traceability. Common data that can be recorded and exported for every single fastening operation includes:

* Screwdriver model and serial number
* Signal (OK/NOK)
* Target Torque
* Final Torque
* Screw #
* Program #, and Program End
* Sequence #, and Sequence End
* Angle
* Time
* Date and hour

As a manufacturer, choosing Kolver for your fastening needs gives you the piece of mind that every single operation in your tightening process is fully tracked and can be traced back to the source, quickly and reliably.
