Manufacturers are able to track and sort tires by reading the Department of Transportation (DOT) codes comprised of alphanumeric characters molded into the sidewall. It’s critical that the DOT code information be recorded at the manufacturing and assembly plant for effective management of potential tire recalls. Code reading is a challenge because tires are often randomly orientated on the conveyor, and there is little visible contrast between the code’s characters and the tire sidewall.

Cognex tire solutions with character reading vision tools enable tire manufacturers to read codes in the most challenging conditions with very high accuracy. The character reading vision tools accurately locate and read the DOT characters and adapt to changes in code appearance caused by variation in the molding process.
