Idea

NECTO abstracts the bionic model of bird bones and transfers their properties
to sheet metal structures

NECTO structures are produced from two parts
in only three process steps:

Cutting,
forming,
joining.

Cutting

In the first process step,
cuts are created in the NECTO sheet.

This is done by punching.
Laser or water jet cutting can also be used for particularly thick or hard sheets.

Forming

In the second process step,

the NECTO structures are formed mechanically.

The relatively large bending radii
and the low elongation during forming
allow the use of hard materials.

Glueing Process

The solar laminate is joined to the NECTO sheet, creating a sandwich. The joints are accessible from the rear side.
They can be inspected for quality control, both directly after the joining process but also during the use phase.

Sandwich-Panels

The sandwich core is open.

That make the sandwich ventilable and condensation is avoided.

The NECTO panels can be of different hight.

Sheet Materials

Aluminum grades such as AlMg3 can be processed. Or grades like aircraft aluminum
according to EN AW 2024.

NECTO sandwich panels have also been manufactured using high-strength (stainless) steels such as FORTA H500/800/1000.

Panel Properties

Core density

The core density can be reduced to a minimum.

With the appropriate structural parameters (sheet thickness, repetition distance, strut width and angle), sandwiches can be produced whose core struts have a volume proportion of only 1‰ of core volume.

When using low-density materials (aluminum), sandwich cores are possible that fall into the category of super lightweight construction (10g / dm3).

Mass production

The NECTO sheets can be produced directly from the coil in a punching production line with progressive dies.

For small quantities and prototyping, punching machines are used to form individual NECTO structures one by one.
