THE APPLICATION |
Catalytic Converter Cores are filled with precious metal slurries and then oven cured. Individual piece traceability (license plate numbering using bar codes) would guarantee that each final filled core ;
|
• Is the correct type • Has passed all tests • Can be traced back to specific lots and/or inspections • Has a complete historical process database |
Traditional bar code labels , or ink jet markings are not suitable for identification since each core goes through several 1200 deg. F curing cycles ( 30 minutes typical) .
Cost / project justification for piece identification
is based on the avoidance of mixed product ( penalties), loss of valuable
customers, and elimination of potential ( very expensive) recalls.
| THE SOLUTION |
Each Catalytic Converter ceramic core is individually
marked at ambient temperature with a 2D Datamatrix Code ( 12 decimal digits)
using InfoSight’s LabeLase
® technology. Marking is accomplished at four consecutive fixtured
conveyor stations.
Patch Painting ( @ Station #1) and Clear Coating ( @ Station #4) each require less than 1 sec. Both coatings are high temperature silicones.
Laser marking requires 2.5 sec. Stepping between stations requires 1.5 sec.
The overall cycle is then 4 sec (15 parts
/ min)
