Frewitt Printing, the specialist of marking solu-tions in the Frewitt Group, and Seidenader Vision, the expert of vision systems in the Seidenader Group, are cooperating for the presentation of a unique laser coding and code verification system. Frewitt has developed a laser marking system using a low energy laser to engrave a Data Matrix code directly on the glass syringe barrel. Seidenader Vision provide the high speed vision system and illumination technique to verify this type of code reliably.
Invisible coding on barrel of prefilled glass syringes either in a dedicated mechanical module or integrated into the infeed of a Seidenader syringe inspection machine.
syringes are fed onto the LC-S module
in hanging position
a high speed laser applies Data Matrix
ECC200 code (ISO 16022)
a camera station verifies that code is
legible and complete
a reject mechanism eliminates products
with defective codes
good syringes are transferred to next
process step
100% traceability of products
unique type of coding against counter-
feiting
highly accurate code application through
precision high-speed laser
visible or invisible codes
partnership of experienced specialists
for customized applications and global
technical support
mass serialization for unique identifica-
tion to isolate potential problems or to
document FiFo processing
