Products from extruders or injection molding machines are used in many different application areas. Thanks to technical innovations, conventional materials can be replaced with products from the extrusion and injection molding industries even more frequently. Permanent marking of extrusion and injection-molded parts plays an important role in the process, ensuring that individual parts or even the entire product can be traced seamlessly. Continuous inkjet printers from LEIBINGER are exceptionally well-suited for marking tasks in the injection molding and extrusion industries. The LEIBINGER camera system can also be used to monitor printed data reliably and during ongoing production.
