Waldorf Technik (Engen, Germany), a subsidiary of the Hahn Group, will showcase a newly developed automation system that allows molders of disposable syringes to print directly on cylinders using the system’s digital printing processes. The system will be displayed at K 2019 at booth D 24 in hall 15.
The system was developed in collaboration with Waldorf Technik’s long-standing partner Netstal of the KraussMaffei group and is based on its Vario TIP system. Syringe barrels can be directly printed after removal from the injection molding machine. Camera systems check the piston stop of the syringe for proper processing. The syringes then are conveyed to the next camera check for proper Luer fitting before being transported to the print station, where they are plasma treated to ensure print adhesion. Drying is performed via UV radiation, following which the syringe barrels can be packed or individually processed according to customer requirements.
The digital printing process guarantees maximum flexibility because the print data is sent directly from the computer to the printer. A modification or print head replacement is not necessary. Waldorf Technik developed this printing solution in collaboration with Hapa AG, using its compact digital print “redcube” module.
