The BMW Group Plant Leipzig has successfully implemented a groundbreaking contactless thickness measurement system based on terahertz (THz) technology from das-Nano for the in-line production of plastic exterior trim components. This innovative solution provides 100% automated, non-destructive testing (NDT) of multilayer paint thickness with micrometer precision in just seconds.
You can read the official announcement in the BMW press release here: BMW Group Plant Leipzig Introduces Terahertz-Based Measurement of Plastic Components in Series Production. In the press release, Christoph Theiselmann, Head of Exterior Plastics, Production at Plant Leipzig talks about our technology: “Terahertz measurement technology replaces complex manual inspection with a fully automated solution, taking quality assurance to an entirely new level.”
Before the introduction of the das-Nano system, paint thickness measurement at BMW Group Plant Leipzig was a manual and destructive process involving scalpels and microscopy, which led to material waste and delays in identifying production deviations. The new terahertz-based thickness measurement system has fundamentally transformed quality assurance at the Leipzig facility by giving real-time thickness data of each coating layer and without damaging the trim parts.
This advancement not only eliminates destructive testing but also significantly reduces material consumption, enhancing overall cost-effectiveness and process efficiency. The BMW Group Plant Leipzig is a pioneer in this field, being the first facility within the BMW Group and the first in the plastics segment to implement terahertz technology for this purpose in series production. And das-Nano is very proud to have been their chosen technology provider. Do you want to be the next one?
To celebrate this successful implementation, we captured an exciting video on-site at the BMW Group Plant Leipzig, showing exactly how das-Nano’s paint thickness measurement system works in the production environment. Check out the video here!
