Rhopoint TAMS™ Total Appearance Measurement System The ultimate quality control instrument that handles: Raw Material E-Coat C-Coat

Instrumental analysis of surfaces appearance, roughness and waviness in the automotive painting process A beautiful smooth finish is a key aim when painting a vehicle- the quality of this finish is determined by the surface roughness & waviness of the raw material to be painted and the effectiveness of each subsequent coating process as well as any polishing or sanding operations. The final paint is built of many layers- as each layer is applied it tends to smooth the material. Measuring the surface at each stage gives opportunities to optimise the overall paint process and understand the...

Take it right from the source 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. Widely used laboratory devices producing 3D topographical maps with a sub-micron accuracy and resolution can only be used off-line, and measurement time is also a limiting factor as capturing a representative area on...

Everything under control - in all intermediate steps The intermediate production step of E-coating (also known as Electrophoretic Painting, Electrocoating, Electropainting etc.) 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 like Sa, gives you complete documentary overview of your paint process. This will result not only in better final quality but also in...

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 and produce complex results. The appearance quality, as judged by the consumer, is determined surface texture which reduces its visual impact. Jointly developed by Rhopoint Instruments and Volkswagen AG over several years, Volkswagen...

Measurements matching visual perception QUALITY One single value predicting the visual rating of the total appearance quality of a surface, with 100% indicating a smooth finish with perfect image forming characteristics. HARMONY Based on extensive human perception research by Volkswagen AG and AUDI AG this value indicates the acceptability of adjacent parts. A value of >1.0 indicates that parts are not similar and if viewed together (e.g. door to door) will detract the eye from overall visual quality.

CONTRAST “C” Contrast is related to the colour of the surface; white and metallic surfaces have low contrast, a deep black measures 100%. Contrast quantifies the visual impact of orange peel and haze effects both being more visible on high contrast dark colours. High contrast SHARPNESS “S” Sharpness quantifies the accuracy of images reflected in the surface, 100% indicates a perfect reflection. At close distances (<0.5m) Sharpness measures how well surface reflects fine details. At showroom viewing distance (1.5m) Sharpness quantifies haze and clarity. High sharpness WAVINESS “W” Correlated...
