Our expertise

The field of hydrogen and high-pressure technology is home to the highest standards for safety, density, resilience and durability. Precision machining is indispensable in this context to guarantee the production of sealing surfaces, threads, or valves with the necessary reliability. Especially with hydrogen – the smallest molecule, which can diffuse even through microscopic leaks – the highest precision is required for all components. In high-pressure applications, too, the surfaces must consistently meet the highest demands in terms of surface quality and purity. Keller Precision is familiar with the requirements placed on the hydrogen and high-pressure sector from decades of experience, offers comprehensive traceability of all processes and works closely with partners from the industry when testing the homogeneity of the material.

Keller Precision deploys state-of-the-art machines as well as testing and measurement instruments for the precision machining of sensitive components in the field of hydrogen and high-pressure technology. With our reliable multi-axis machining, we are able to machine highly complex geometries or freeform surfaces in a single operation. This increases the efficiency of our employees in the machine park, while also minimising the tolerance deviations that can occur during clamping. Our employees’ extensive expertise goes far beyond traditional machining processes, which is why Keller Precision is always able to respond to complex customer requirements with application-oriented special processes.
