LAB Italia Day 1

The renowned LAB Italia exhibition in the heart of Milan got off to an impressive start: Throughout the whole exhibition day, a large number of visitors came to the URAI booth to learn about technical developments in the laboratory world.

URAI offers innovative solutions and instruments from leading international companies enabling its customers to achieve highest quality in laboratory testing. URAI will present the OptiSense non-contact mobile and industrial measuring systems for precise and contact-free testing of coating thicknesses.

OptiSense coating thickness expert Jörg Mülleneisen came from Germany especially for the trade fair and will advise you on even the trickiest coating-substrate combinations during LAB Italia. Take the opportunity to have all your questions answered at the URAI booth until June 19 at the NH Milano Congress Center | Milanofiori | Booth 106.

Coating thickness measurement for the Easter bunny: Paint on lime

We recently received a particularly tricky inquiry about coating thickness measurement from Eggtown: Can we measure paint on lime on curved surfaces? - Our answer: Of course!

With the PaintChecker Mobile, everybody can now check whether the paint application on all Easter eggs is correct (see photos). With this in mind, Happy Easter!

BESSER LACKIEREN online presentation on Wed, March 13 at 12:40 p.m.

Coating requirements are constantly increasing, and so are the needs for end-to-end process control. Nico Janssen, Development Manager at OptiSense, will talk about automated production quality assurance in the line and how it helps to optimize quality, reduce costs and save resources.

Real-life examples of non-contact testing in the automotive industry and battery production show ways to make production more efficient and meet growing quality requirements

The forum presentation will start in the Schaufenster der Innovationen of the professional journal BESSER LACKIEREN on Wednesday, March 13 at 12:40 pm.


An entirely successful conference with battery industry innovation topics

Every year, WEKA Fachmedien invites you to Battery&Power World in Munich. In 2024, more than 200 congress participants will once again discuss key topics in battery production and application with international experts. This year, the main focus was on the challenges posed by the required efficiency and environmentally friendly production of battery systems.

Speaker Dr. Fabian Gaussmann, Strategic Product Designer at OptiSense, summarized his impressions of the symposium, which ended on Thursday: "The compact expert presentations and workshops as well as the accompanying exhibition presented current trends and technical innovations and left plenty of time for networking. - For an optimum system, all components must work precisely together. For the technical experts, this means addressing the issue of battery safety, and for battery manufacturers, it means dealing with coating thickness measurements."

Well attended: Wagner Symposium in Warsaw

Around 600 visitors came to Warsaw (Pl) last week for the Wagner Symposium at the Hilton Congress Hotel.

The agenda focused on information about innovative application techniques, optimized paint coating and measuring and testing technology. Sustainability, energy efficiency and the CO2 footprint played an even more important role in many presentations than in previous years. Several case studies and panel presentations provided an insight into the capabilities of current plant technology. The presentation by Piotr Szulc, the Polish OptiSense distributor, showed interesting ways of optimizing processes and reducing the costs in modern coating jobs.

With around 70 exhibitors, the industry show was also well booked and was a highly popular point of contact for visitors, not just during the breaks.

18th Wagner Symposium in Warsaw

The Wagner Symposium in Warsaw (Pl), taking place from February 21-23, has become the largest coating industry event in Europe. Visitors can expect an interesting range of presentations from leading experts in the industry. At the same time, there will be an exhibition area showing solutions, products and innovations relating to components, coatings and equipment for the coating industry.

The objective of the event is to present practical knowledge and exchange experience of the painting process. And of course OptiSense will also be there. By the way: over 200 companies and 600 visitors took part in the last event.


Battery & Power World 2024 in Munich

On February 27 and 28, 2024, Battery&Power World will take place as a professional conference for battery technology at the Science Congress Center Munich (SCCM). OptiSense will be there with the presentation Automated Quality Assurance in Inline Battery Production.

The OptiSense presentation on Wednesday, 28.02.2024 at 16:15 h will show practical examples of numerous solutions for automated inline integration of non-contact coating thickness testing in order to optimize all process steps in the line, make battery production more efficient and meet the growing quality requirements.

Experts in electromobility (electric land, sea and air vehicles) and renewable energies/smart grid as well as industrial and medical technology will meet at Battery&Power World.


2024 will be an innovative year

The first day of the new year - we look forward to many exciting topics and, in particular, innovative OptiSense solutions in 2024!
