Ensure quality, reduce costs thanks to measurement and control systems

Mahlo at the ICE Europe 2023

Mahlo GmbH + Co. KG presents solutions at ICE Europe

Mahlo is looking forward to ICE time in Munich: From 14 to 16 March, the German manufacturer of measuring and control systems is expecting trade visitors from the Coating & Converting industry at stand A5/1510. They can get an overview of the broad portfolio for quality control technology. Particular focus will be on process reliability and cost savings.


"We not only present concepts on how to increase fabric quality in a demanding coating and converting market, but also address the current challenges manufacturers are facing at the moment: rising raw material prices, long delivery times, no room for misproduction," says Matthias Wulbeck, product manager QCS at Mahlo. Informing customers and advising them on the appropriate systems to optimise the entire production set-up is one of Mahlo's core competencies, he says. The quality control system Qualiscan QMS-12 is exactly the right tool for the job. The renowned online measurement and control solution determines parameters such as thickness, basis weight, density, coating thickness and moisture. The modular system impresses with a wide range of measuring frames in different sizes and sensors for almost every requirement.


Measuring sensors in live operation

At the ICE, Mahlo presents, among other things, the Webpro XS measuring bridge, the most compact variant of the O-frames. Installation is therefore possible even in confined spaces. The Webpro XS manages fabric widths from 0.2 to two metres and can accommodate a Mahlo sensor. The Optoscope WLI-R-UV/VIS white-light interference sensor with continuous thickness measurement of various foils is installed on the exhibit. It can measure thicknesses from 200 nm on clear, transparent films.

Mahlo will also present two sensors on a demo tower, which are mainly used for complex requirements. The Infrascope NIR measures important product-specific parameters such as moisture and basis weight without contact by absorbing infrared light. By simultaneously analysing the entire NIR spectrum, the sensor can distinguish between several components in a material web.

The Optoscope WLI-R-NIR is used for particularly thin or even opaque layers where other systems reach their limits. Using a white light interference method, the sensor can measure paint coatings down to 0.4 µm thickness. For adhesive coatings on polymer films, it is possible to measure minimal coatings down to 1 µm. In addition, the Optoscope WLI-R-NIR is able to indirectly determine extremely thin coatings on aqueous or solvent-based films, depending on the solid content. Continuous further development of the sensor has ensured that there is virtually no pass-line effect. This guarantees the most accurate measurement results.

"Passline measurement and control technology in the production line is in demand as never before, as the amortisation period has been drastically reduced due to the constantly rising costs of energy and raw materials," says Wulbeck. "With our systems, we support our customers in remaining economically successful."
