The KLM 621 laser marking-on-the-fly machine from Kistler can be integrated directly into existing punching lines.

Laser marking-on-the-fly (MOF) of continuous materials – high precision combined with high speed

Our LASERmark KLM 621 laser marking machine comes equipped with all the components needed for strip transportation and labeling of continuously produced punched parts with marking-on-the-fly (MOF). The KLM 621 – it can be used for a variety of materials – is a flexible, high-performance system that operates autonomously and can be integrated directly into punching, injection molding and assembly lines. 

The main purpose of rapid, permanent end-to-end marking and labeling of parts is to ensure traceability – a key factor in quality assurance for every production facility. Parts can also be counted and separated. 

Marking and coding continuous material during the production process is a highly cost-effective method – because there is no need to stop the belt, and setup costs are eliminated. 

Another benefit of laser marking-on-the-fly: the exceptionally high cycle rate of over 2,000 workpieces per minute boosts your manufacturing line's productivity. Our LASERmark KLM 621 is designed for continuous operation. Each workpiece can be individually marked with numbers, characters, codes and safety-relevant features. 

Coupling to the process only requires a release signal and an interface to the master control.
