The Powder Coating Week

The OptiSense booth at the Powder Coating Week in Orlando (Florida) USA was very well attended and successful. The Powder Coating Week took place on Feb. 6, 2023 in Orlando/Florida. One of the main objectives is the strong commitment to continuous education of the powder coating industry. The high-profile event was hosted for the 30th time by the Powder Coating Institute (PCI).

OptiSense celebrates with a limited edition

For our 25th anniversary, the PaintChecker Mobile will be released in a limited edition with an exclusive color. The great thing is that our  fans can vote online for the ultimate look of the "PaintChecker Mobile 25 Years". And with a little luck, everybody taking part can win one of the hot prizes with a total value of over 5,000 Euros.


25 years of OptiSense: „The secret to success: be visionary every day!“

OptiSense turns twenty-five and is in its prime. On this anniversary, Managing Director Dr. Jens Heymans briefly reviews the history of the company and provides an insight into the topics and technologies that are currently driving OptiSense and its customers.

What our customers say

Dr. Felix Zabka, Managing Director of ConceptColor, explains the advantages in quality control when OptiSense coating thickness measurement systems are used – directly in the line in this application.

For the beginning of the new year

"And there is magic in every beginning," wrote Hermann Hesse. That's what we wish you for the beginning of the new year.  May the glow last for the entire twelve months - combined with good luck and, of course, plenty of health!

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.
