Stories about coating

Shifting boundaries. Going over the limit layer by layer. Welcome to our world of PVD high technology, where everything is ultimately very simple despite the high level of complexity! Because we have known what counts for our customers for more than three decades: Quality, reliability and speed.

Our values






“We started out in the 1990s as a plant manufacturer and soon also offered component coating. The response was great, as the topic of surface optimization was new to most companies. Today, it is less about developing new coatings. The core coatings cover 90% of the market and will continue to do so in the future. What counts for the customer is that these coatings can be produced stably, reliably and quickly.”
— Jürgen Lohmann, company founder, Forschergeist,
Coating pioneer

PVD coating in premium quality

Jürgen Lohmann laid the foundation stone for this with the founding of GPA in 1993. A classic representative of German engineering and an inventor who developed the machine technology that is our core competence today. At its heart is the particularly simple and reliable arc evaporator technology.

Our fully automatic PVD-Arc systems have been used for many years around the world, in Europe, the USA and the Far East. The way in which Jürgen Lohmann has optimized and standardized his developments in terms of process technology has made us the coating professionals we are today and has allowed us to deliver the best possible PVD quality for your tools and components for many years.

Our strategy: Customer First

GPA is a medium-sized company in which the long-term success of the company over generations counts. Our business strategy therefore prioritizes values such as experience, sustainability, effectiveness, reliability and integrity.

Thanks to our decades of experience, we have a good understanding of our customers’ individual needs. We support them in using resources correctly and not wasting more time and energy than necessary. It also helps that GPA is now headed by Richard Kallee, a man who, as a former managing director in the international engine and vehicle industry, not only knows the customer perspective, but also understands the concept of lean management.

“Our mission has always consisted of a single question: How can we achieve long-term success together with our customers? By solving their problems and being a partner at eye level: Always with the aim of extending the service life of their tools, saving time and therefore resources, minimizing downtimes and reducing costs. And by making our customers’ work easier and working with us as simple and pleasant as possible.” — Anne Lohmann, built up the GPA with her husband Jürgen Lohmann
