Case Study: Identification through pre-treatment
and annealing of steel wire coils and bars

ProductSteel Wire
ProcessPickling ( HCL and H2SO4 )
→ Heat treatment ( 800℃ x 10hours )

Customer’s request

  • Product ID management
  • Eliminate identification errors and lost coils
  • Reduce of Labor cost.

Initial Process Management

Identification using standard PET tag

Process Issues

  • PET tag doesn’t have enough heat resistance, so it has to be detached before heating process.
  • Product misidentification occurs when PET is reattached after heat treatment.


1Utilize a high temperature barcode tag that can survive all processes.
2Eliminate identification errors caused by attaching the wrong tag to wire coils
