Mahlo GmbH + Co. KG, a leading manufacturer of measurement, control and automation systems from Germany, participates together with its long-time agency Toyo Machinery Co. Ltd. in the Converting Technology Exhibition that takes place from 30 January to 1 February in Tokyo. Visitors can discover the latest developments of the German technology forge at booth 3L-14 in East Hall 3.
In order to monitor and control web-type products even better, Mahlo has expanded its already broad portfolio of high performance sensors for its quality control system Qualiscan QMS. Mahlo’s clients can benefit from additional options, with which parameters such as coating thickness, basis weight and moisture can be determined. “Our sensors for basis weight measurement, like the Gravimat FMX and the Gravimat DFI has been established in the Japanese market for many years”, says Area Sales Manager Clemens Kaplan. Those products are mainly put to use in the automotive sector and with technical textiles. At Convertech, the experienced trade show team focuses on the complete application range of coating and converting, including nonwoven, textiles, plastic films, papers, ea.
Visitors at booth East Hall 3 / 3L-14 have the chance to examine the Mahlo sensors Infrascope NIR as well as the sensor Optoscope WLI in detail. The first mentioned measures the absorption of infrared energy and can identify basis weight and moisture at the same time. Due to its very high spectral resolution, the sensors can distinguish between components with similar IR absorption. That allows the highly selective measuring of a specific component or coat without affecting other components. This way, very thin silicon coatings with 0,3 – 0,5 g/m² can be measured easily and precisely.
With especially thin coats, where other systems reach their limits, the Optoscope WLI is used. With the help of white-light interference phenomenon, the sensor is able to measure varnish coats down to a thickness of 0.4 µm. What’s more, the Optoscope WLI is able to determine even extremely thin coats in the nm range indirectly with aqueous or solvent-based applications on film, depending on the solids content. The sensor’s continuous development guarantees exact measurement results.
“Thanks to the clear software visualization at the control screen of all Mahlo-sensors, the user has the complete features and results at one glance”, says Kaplan. That way, the operators can analyze the obtained values, make changes if necessary and save data. The trade show team is ready for questions regarding these or other Mahlo systems.
