What we stand for
From technical challenge to a manufacturable end product.
We help clients move from a technical challenge to a manufacturable end product. From components and series to assemblies, tools and machines: we contribute ideas and take responsibility for the agreed manufacturing process.
An industry that produces better and more sustainably.
We aim to improve production processes through sustainable technology. By connecting craftsmanship, innovation and collaboration, we build solutions for tomorrow's industry.
Our locations
Our people and disciplines strengthen each other. Appelscha focuses on series production; our other manufacturing comes together in Leeuwarden. What matters to you is the end product, from one Douna.
Sustainable business
With solar energy from our own roof, we generate more electricity over a year than we consume ourselves. Batteries store generated electricity for later use. This gives us greater control over our energy supply and reduces dependence on direct electricity input.

The people behind the technology
We have been developing our craftsmanship since 1924. We pass that experience on in the workshop and to a new generation of skilled people. At the same time, we keep learning, developing and collaborating.
