In the aerospace sector, these activities enable metal components, generally made from aluminium, which subsequently form the various component parts of an aircraft, to be produced: electrical racks, equipment racks, passenger door frames, etc. Sheet metal working consists of cutting flat metal sheets to create more complex forms.

Based on numerous parameters, this operation can be carried out manually, using a press or appropriate tooling for specific components, with a possible quenching phase to soften the material.

Following surface treatment and painting, sheet metal working enables these components to be adjusted and then assembled, in different stages including drilling, riveting and even bonding. Ultimately, this creates sub-assemblies that can include up to 600 components.
