OptiSense early warning system saves tens of thousands of euros

During the live event of trade journal BESSER LACKÄR at Giga Coating in Twist, OptiSense Sales Manager Jörg Mülleneisen gave a presentation on coating thickness inspection systems for even more resource efficiency in coating.

It was no coincidence that Mülleneisen titled his presentation “Coating thickness measurement as a profitable adjusting screw”: host and OptiSense customer Giga-Coating was able to confirm that the company would have to reckon with a loss of several thousand euros if only a single part was overcoated.

These faulty coatings are now detected by the PaintChecker Mobile, the non-contact OptiSense test device, as an early warning system even before the curing oven.

OptiSense goes QIB

OptiSense will have an information booth on non-contact coating thickness measurement at the QIB Jubiläums-Praxisforum on November 17-18 in Wetzlar. In addition, Sascha Schmidt, OptiSense Sales Manager, and Martin Kolenda from the Metob group, will talk about "All-in-One Coating Thickness Testing of Highly Complex Components as a Profitable Process Tuning Parameter".


Resource efficiency becomes a competitive advantage

Rising material and energy prices as well as costs for scrap and disposal make the efficient use of resources an economically attractive challenge for coating companies. Test and measurement technology can make an important contribution to resource efficiency. The interview with OptiSense Managing Director Dr. Jens Heymans shows the potential and also gives a glimpse into the company's green ideas.

The measurement system in the heart of the process ensures first-class quality assurance

As soon as the parking sensors leave the powder booth, the coating thickness is immediately checked for each individual part. The measuring system consists of a controller as the processing unit, connected to the sensors via cables. The PaintChecker controller is attached directly to the powder coating booth. Before curing, each of the tens of millions of freshly coated parts travels on a conveyor belt through the inline measuring station, where the coating thickness is checked without any contact by a laser sensor.

ZVO-Oberflächentage are a big success

Experts in electroplating and surface technology met in Leipzig. Around 500 participants could learn from OptiSense how coating thickness can be measured in industrial environments at high speed and accuracy with maximum stability. Sales Manager Jörg Mülleneisen presented the non-contacting OptiSense sensors and answered questions about optimized process quality as well as significant cost and energy savings.

Lackier- und Pulvertreff focuses on resource efficiency

At the JOT Lackier- und Pulvertreff in Mannheim, the industry looked at the "hot potatoes" of resource efficiency and sustainability. OptiSense Sales Manager Jörg Mülleneisen opened the second day's presentation program with the exciting topic "Learning from Swarms". He showed how mini-sensors can support industrial coating companies to optimize process quality by proper coating thickness measurement and save costs and energy at the same time.

Prize puzzle: Puzzling resources

Simply answer the five quiz questions and with a little luck you will win one of the precious prizes – regardless of how many answers are correct.


Simultaneous tests on neuralgic parts of an enclosure

The PaintChecker Industrial photothermal measuring device for non-contact, non-destructive coating thickness measurement can operate with multiple sensors at the same time. The sensors are small enough to fit side by side even in confined installation spaces. The tiny, point-shaped measuring spot allows to precisely measure even the smallest components. The device is suitable for wet and dry organic coatings such as paints, varnishes and powders on metal, rubber and ceramics.
