At Theilen, quality doesn’t end when a component is finished. It is reflected in how precisely it is manufactured, how thoroughly it is tested, and how comprehensively it is documented.

Because, especially when it comes to sophisticated components and systems, it’s not just the end result that counts. It’s also crucial that the process is traceable.

That’s why we combine modern measurement technology with defined testing processes, experience, and a clear commitment: What we manufacture, we can also measure, test, and verify.

We have an air-conditioned measurement room at our disposal for testing our components. This allows us to create controlled conditions for precise measurements and reliable results.

Among other tools, we use the state-of-the-art Keyence XM-5000 for 3D measurement technology. The equipment is supplemented by a FARO measuring arm, which allows even complex geometries to be captured flexibly and directly on the component.

Calibrated measuring instruments such as calipers, roughness and depth gauges, and limit gauges are also available for the respective inspection tasks.

Upon request, we prepare FAI documentation (First Article Inspection) and ensure the traceability of components and associated test reports.

This turns a single measurement into verifiable proof of quality.

A precisely manufactured component is one thing. The certainty that its quality has been verified and documented is another.

Our quality assurance provides precisely this assurance: for individual components as well as for complex assemblies and complete projects.

Measure precisely. Document clearly. Traceable with confidence.

Because for us, quality is not a promise made at the end of production.

It is part of the process—and visible in the result.
