Mastering the challenges of the plastics industry together

Worldwide known, at home in Germany. What applies to the K Show, which takes place from 16 to 23 October in Düsseldorf, also applies to Mahlo GmbH + Co. KG. The mechanical engineering company from the Bavarian hall will be presenting its renowned solutions for quality control and regulation of critical process parameters at Stand 10G21 at the world’s most important trade fair for the plastics industry. 


“The challenges for the plastics industry continue to grow,” says Matthias Wulbeck, Area Sales Manager QMS at Mahlo. “Manufacturers should produce more effectively and save resources at the same time”. To make this possible in practice, Mahlo offers concrete solutions with the Qualiscan QMS quality measurement system. The modular system, which is also composed of sensors and measuring frames, measures, records and controls critical parameters such as basis weight, moisture or layer thickness over the entire fabric width. In this way, the energy efficiency of the production systems can be drastically increased, the raw material costs can be optimized and production can be more sustainable.

At the Mahlo booth, visitors can get to know the latest developments “made in Germany” from the comprehensive sensor portfolio. In live operation, the experts will be demonstrating with measurements on various product samples. One sensor used is the Infrascope NIR sensor, which uses infrared radiation to determine measured values. It monitors the absorption of infrared energy of all components on or in the material web in the near-infrared range. “By evaluating different absorption spectra, the moisture content as well as the basis weight of different other materials in the web can be determined simultaneously,” explains Wulbeck.

Answers to challenges in plastics processing

The Optoscope WLI, on the other hand, uses the white light interference method. It can measure minimal application quantities down to 0.4 µm and is therefore the optimum solution for particularly thin layers where other systems reach their limits. In addition, the latest version of the Optoscope WLI offers an even wider range of coating thicknesses thanks to a high-resolution and highly sensitive spectrometer. “The continuous further development of the sensor has ensured that even more accurate measurement results can be obtained,” says Wulbeck. As a representative of the various measurement frames of the Qualiscan QMS system, Mahlo introduces the Webpro XS-II. The measuring bridge is the most compact version of the O-frame. Installation is therefore possible even in confined spaces.

A visit to the Mahlo stand is therefore worthwhile for the trade fair visitors, because: “With our systems, which we would like to explain to the audience at K in more detail, we would like to provide answers to important and urgent questions for the world of plastics processing”.
