The mark of a perfect finish is a flawless look and optimal protection. To achieve this in automatic painting lines, several coats are applied wet-on-wet without intermediate drying. After each pass, robots check the fresh paint at numerous points, without making contact. Just seconds remain to approach the measurement point and carry out the measurement. This is the ideal task for our miniature sensors. Weighing in at just 150 grams, they can be mounted on fast, lightweight robots that can handle high cycle rates.
But coatings today no longer serve solely decorative purposes. A booming sector are anti-friction coatings, which are now used for noise damping by almost all car manufacturers and automotive suppliers.
These are typically applied to interior components such as cup holders, armrests, door panels or storage compartments. Microscopically small containers filled with lubricant are embedded in a coating layer and release their lubricant charge to the friction or lubrication point under load. This creates a high-performance lubricating film between the friction partners and prevents disturbing noises – provided that the coating thickness is within the given tolerance range. And this is where the OptiSense test systems come in.
