Mahlo presents its Qualiscan QMS at Chinaplas

One of the leading trade shows for plastics and rubber summons international key players once again. From 21 to 24 May the Mahlo-Team around Chinese representatives Frank Fei welcomes experts from all over the world at booth 5.1 S01.

At the Chinaplas 2019 in Guangzhou plastics and rubber are in the spotlight for four days straight – from raw material over production and converting machinery to coated goods. Over 180 000 visitors gathered information on the latest trends and technologies at last year’s event. This time even more are expected. For a very good reason: the demand for plastic products is steadily increasing. At the same time, sustainability gets more and more important. And that already starts with the production process. Mahlo is up for this challenge with its Qualiscan QMS! “The modular system measures, records and controls critical parameters such as basis weight, moisture or layer thickness over the entire width of the product”, explains Frank Fei.

Visitors at the booth 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 for a highly selective measuring of a specific component or coat without affecting other components”, says Fei. 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.

Sound interesting? The Mahlo team happily provides information on individual solutions.
