BOA AG: Forming tools for the production of expansion joints and metal bellows
BOA produces expansion joints and metal bellows for the automotive, aerospace and energy sectors. For its own needs, the company developed machines for hydrostatic tube forming. All the forming tools for this are supplied by Durrer.
The important thing here is maximum precision in production. Since hydrostatic tube forming is carried out with the aid of osmosis, rust is a decisive factor in the choice of material.
Durrer and BOA have been working together for many years. This means that we also provide BOA with advice and support in further tool development. Thanks to the know-how we have acquired together, we have been able to continually increase precision and optimise production.
