Processing of webs
Converting a material means changing the original material - the substrate - into something new. Typical converting processes include printing, laminating or applying a coat onto the substrate. Among the many converting processes coating is one of the most frequently used ones. For most coating & converting technologies the use of webs has become standard.
The industrial process of coating usually consists of the application of an additional layer to a substrate, such as fabric, paper, film or foil. Depending on the designated use of the material, coatings can be decorative or functional.
The Coating & Converting market is very diverse and demands a quality control system that is both flexible and configurable. In addition, these industries have become increasingly more competitive resulting in tighter product specifications and more challenging profit margins.
Mahlo’s extensive expertise in providing sophisticated technologies covers more than twenty-five years. Our experience and understanding of converting processes have allowed us to tailor quality control systems suitable for every process requirement.
Systems from fixed measuring points to traversing measuring systems for single and double-sided measurement with several synchronized scanners are available.
With the comprehensive portfolio of sensors, important parameters such as basis weight, coating weight, moisture or thickness can be recorded, logged, and controlled. The measuring methods range from beta gauges and X-ray sensors to infrared, microwave, laser or white light interference and airflow measurement.
