SECAMnida© is not just a potted insert for honeycomb sandwich panels.
Its highly reliable technology  revolutionizes installation. 

This fastening has a reinforced locking thread and is  crimped onto the upper skin of the sandwich panel  by deformation of the part. This effective anchoring  permanently holds the insert in position and means the  panel can be handled without risk, unlike the current  inserts which are held in place simply by a self-adhesive  “positioning” tab and which can tip in their hole before or  during the potting operation. 

After crimping, the two-component potting compound can  then be injected,
and filling is accurately controlled by the  filling indicator.

Whereas the current NAS inserts require seven operations  to install them (drilling, trimming, etc.)
and immobilisation  of almost 24 hours for full curing, the SECAMnida© insert offers unrivalled efficiency.
It is fitted in only three steps,  reducing the installation time from two minutes to thirty  seconds,
and the panel can be handled immediately to  continue its manufacturing process.

AUTOMATION A SURE BET WITH GEBE2

The two industrialists began working together at the Paris-Le Bourget  Air Show in 2019. Aware of the difficulties and costs linked to  automating the installation of NAS-type potted inserts, GEBE2 was  seeking a reliable, economical solution.
An exclusive partnership agreement was signed to progress beyond  the idea stage and produce a demonstrator.
The study was launched  and GEBE2 developed an all-in-one robotised effector able to drill,  crimp, inject the potting compound and perform a fully automated  final inspection. 

The alliance between the two industrialists has led to a fully robotised solution for the installation of fastenings in all types of sandwich panel, both honeycomb and other.

It offers numerous advantages:
• Improved repeatability of the insert installation operation
• Automation of quality control
• Possibility to provide traceability of all the operations
• Versatility and adaptability of the system to the geometries of complex parts
