Coding of Particle Filters
Definition of Task
- Ceramic particle filters for the automotive industry are coded with a CO2-Laser while resting in two parallel operating machines
Special Product Specification
- Code consists of four arrows indicating the flow direction and a data matrix code
- Data matrix code consists of an automated date field and a six digit counter
- Date is encoded by the julian day and two digits indicating the year
- Counter is initialized each day
- Since the ceramic material reacts by showing a black color change, the data matrix code is printed as positive
- Next to the data matrix code its content is printed as a readable alphanumerical code
REA JET Solution
Advantages of the REA JET Solution
- Customer has chosen the REA CL laser system for its high print image quality and for the reason of printing indelible marks on the ceramic filters
- Especially the automotive sector products are exposed to extreme environmental conditions for several years and still have to meet the tough traceability requirements which are mandatory in this industrial sector
