The German region of Bergisches Land, comprising the three cities of Wuppertal, Solingen and Remscheid, has a long and successful history of metalworking. Yet in the shadows of this traditional industry, smaller high-tech companies are also playing an increasingly important role, enhancing the regional portfolio with intelligent and ingenious technologies. Wostor GmbH, founded in Remscheid in 1967 as a steel stamp factory and engraving shop, has developed over the years into a company specializing in pioneering solutions for product labeling and computer-controlled product identification/tracking using dot peen and laser marking systems. Now named SIC Marking GmbH, the company is at EMO Hannover 2017 to showcase an innovative laser marker that can mark various levels on a workpiece without having to reposition it.
The new multilevel laser marker is ideal for marking virtually all materials, with exceptions including gold and copper. Marking is possible even with difficult surface conditions thanks to a liquid lens in the laser marker, like those used in smartphone cameras. The liquid lens is controlled by an electrical signal and can be reshaped, thus adjusting the focal length. "Height differences up to 80 millimeters are no problem with the liquid lens," explains Christoph Lange, Head of Engineering at Sic Marking in Germany. He points out that, although a conventional laser marker is sufficient for around 90 percent of all applications, the number of special applications that involve greater space requirements for marking, complex workpiece geometries and falling cycle times is constantly increasing. The new multilevel laser marker can be used on all SIC Marking workstations that use a PC and Sic Laser Advanced software, such as the L-Box and XL-Box.
