To evaluate the suitability of raw materials, to optimize individual processes and to build a complete picture of how the quality of the final product is influenced at each paint stage, analytical data is needed to understand how each paint process fills, smooths and masks the underlying roughness from the base material such as steel and aluminum.
The image-acquiring Rhopoint TAMS™ utilizes Phase Measurement Deflectometry (PMD) as one of its measurement technologies and provides ISO 16610 compliant high-resolution 3D altitude maps of raw materials and all surfaces in the painting process in less than five seconds.
Measurements are taken according to DIN EN ISO 4287 (like optical Ra), or DIN EN ISO 25178 for areal topographic information (like Sa).

Everything under control - in all intermediate steps
The intermediate production step of E-coating is a high-tech process that has a huge impact on the final quality and thus requires as much control as any other production step.
Controlling the E-coat with Rhopoint TAMSTM and its advanced quality parameters, e.g. ISO GPS texture analysis compliant topographic roughness indices, gives you complete documentary overview of your paint process. This will result not only in better final quality but also in lower unit costs.
But not only can relevant topographic indices be analyzed. If you want to keep it simple, Rhopoint TAMS™ enables easy documentation and reporting by using Rhopoint Quality indices to judge overall quality of an E-coat.
Clear coat measurement - judge the perceived Quality as your customer does
For maximum visual impact, an automotive paint finish must instantly produce an appealing visual sensation for the customer. Improved correlation to visual perception and its easily communicated parameters gives the Rhopoint TAMS™ a major advantage over methods that are currently in use.
Clear coat measurements are made by the Rhopoint TAMS™ by measuring a 2D area of the surface from a fixed measurement position. In addition to providing major surface parameters such as Contrast, Sharpness, Waviness and Dominant Structure Size, customer visual preferences are shown by “Quality” and “Harmony” indices. The Quality indices express the overall quality level of the surface, whereas the Harmony value indicates how well adjunct parts will are be perceived as harmonious in quality.
