Douna Group

The Douna Group consists of four companies that enable turnkey outsourcing of a technical project to a single service provider. We take care of the process from idea up to working machine/production line.


As every process step has its own specialism the activities are subdivided in 4 companies. Naturally, you can approach each company separately.
