Measure & Test

In addition to the coating thickness, the color tolerance or adhesion strength is also part of the quality control. Numerous different measurement methods are used here - from eddy current measurement to thermographic determination of coating thicknesses. An increasing topic is also the inline control of processes, which is gaining in importance in the context of Industry 4.0.

Measuring the layer thickness of antique resin paints with PaintChecker

Noise caused by oscillations and vibrations when driving has long been an absolute no-go in all vehicle classes. Reason enough for car manufacturers to invest in the improvement of anti-squeak coatings and coating thickness measurement.

Non-contact coating thickness measurement with handheld device

Dörken uses Advanced Thermal Optics in non-contact coating thickness measurement

The coating thickness of an anti-corrosion solution plays an important role in the functional properties and fit dimensions of components. In order to be able to measure this directly during series production, measuring systems based on advanced thermal optics are used.

OptiSense: Large parts - precise coatings

Giga Coating GmbH coats components weighing up to nine tonnes in Twist using a CDP line and two powder coating systems. The parts come from all over Europe and the order volume is around 1.5 million square metres per year. Quality control and thus compliance with minimum coating thicknesses, but also the avoidance of overcoating, therefore play a central role.

Helmut Fischer: Measuring galvanic baths continuously

With a new, automated technology based on X-ray fluorescence, precise monitoring of the metal concentrations of up to four electroplating baths is possible automatically and continuously.

OptiSense ensures sustainable coating of window regulator guide rails

The precise coating of window regulator guide rails on both sides is crucial for the function of window regulators. The requirements in the automotive industry are high. An inaccurate coating thickness must not represent a risk of corrosion or a functional risk.

dfo: Determining the color shades of effect coatings precisely

Effect coatings look great, but usually place higher demands on the coater when it comes to coating. In the case of decorative panels in facade construction, there were strong visually perceptible color differences between the individual panels. Because two experts had already come to different conclusions, DFO was commissioned to determine the color shade.

How to avoid surface defects

Automated coating lines can now be supplemented with an online inspection system. With four cameras, coatings and edges of sheets or web goods are simultaneously checked for cleanliness as well as correct position and size.

Layer systems in electronics

Quality inspection is becoming increasingly important in industrial production. Highly complex coating systems and component geometries as well as the required precision of the measurement results and the shortest possible duration of the measurement ensure constant pressure to innovate. This also applies to the electronics industry.

Intervene early instead of reworking

A structural fingerprint of a coating by a portable interferometry measuring system allows the detailed analysis of multi-stage coating processes - from the substrate to the clear coat. This allows early measures for process optimisation and reduction of quality costs.

What a lying drop can reveal

The density and contour of a drop says a lot about the properties of a liquid. A measurement technology provider expands its portfolio with the Constrained Sessile Drop method and shows how test liquids or hot melts can be subjected to rapid purity testing via video analysis.

Rejects minimized by inline measurement

For many years, Stobag AG has placed great emphasis on process efficiency and sustainability. This also includes checking the coating thickness before stoving. With a flexible photothermal hand-held measuring device, the company manages to reduce its rejects in the paint shop to less than one percent.

Measure and inspect surfaces optically

The surface properties of a product influence its mechanical, electrical or chemical behaviour. Only a quality-monitored manufacturing process can ensure the desired result - optical measuring methods open up new and interesting possibilities here.

Tracking down the smallest residues

Laser-induced plasma spectroscopy can be used to analyse the components of a surface and detect contaminations. Within the ALASKA project funded by the BMWi, this technology was successfully transferred into a fully automated unit for complex process chains.

Closing the control gap

Quality tests in the automotive industry are often carried out with non-calibrated devices. A calibration standard facilitates the control of the technical cleanliness test in rinsing cabinets.

spectro2profiler color 3D structure measuring device

BYK-Gardner introduces a completely new, innovative measuring instrument for determining colour and gloss as well as for analysing the 3D topography of textured surfaces: spectro2profiler.

Mobile coating thickness measurement

A Cologne-based manufacturer now enables coating thickness measurement with an app and radio sensor. The conventional measuring device is replaced by a radio sensor and the associated app takes over all the tasks of a professional coating thickness measuring device and is available mobile on smartphones and tablets at any time.

Paint inspection with terahertz waves

Precise adherence to coating thicknesses is an important quality parameter in modern automotive painting. The problem here is that the non-destructive methods commonly used today often fail with multi-layer systems. A new type of paint inspection system based on terahertz waves promises an industrial solution.

Proven in practice: Inline spray control

In spray processes in industrial production, surface defects are often detected too late or not at all. This results in rejects with high follow-up costs and claims for damages. A measurement technology specialist controls spray quality in real time with high-tech solutions and uses AI for preventive defect detection.
