Fraunhofer Institute for Physical Measurement Techniques IPMInspection of cleanliness and coating
Component surfaces are a key element in the quality of industrially manufactured products. Surface impurities can impair the function of components or lead to faults in the subsequent manufacturing processes. In food production plants, impurities lead to fouling – regular cleaning processes can be specifically adapted here on the basis of measurement data. Functional coatings on component surfaces must meet specific requirements in terms of thickness or composition in order to fulfill the desired function. Inspections of cleanliness and coatings therefore play an important role in industrial quality control.
Customized system for specific applications – in the laboratory or in the production line
Fraunhofer IPM develops measuring systems for the inspection and analysis of component surfaces. To this end, we use various laser- and camera-based methods, including fluorescence measurement technology, IR reflection spectroscopy and laser-induced breakdown spectroscopy. Depending on the individual measurement task, we combine the various technologies and adapt the optics and lighting to achieve optimum measurement results. Our systems inspect components of different sizes and geometries – from body panels to strip metal and small components.
Sensitive, yet robust for the use in production
Measuring systems by Fraunhofer IPM can be used in the laboratory or in the production line – as stationary units or on robot arms. In accordance with the requirements, they inspect the cleanliness and coating of component surfaces completely, by imaging and with spatial resolution. Depending on the system, quantitative measurements, classification of particles or analysis of the element composition on the component surface are possible. Our systems measure layer thicknesses down to the nanometer range and detect contamination of just a few milligrams per square meter. At the same time, they are designed to be robust and perform measurements so quickly as to enable control of cleanliness and coating inspection directly during production.
Measuring systems for surface analysis by Fraunhofer are used wherever particularly reliable measurements are required – from automotive manufacturing to food production and medical technology.
