Laser Marker

Overview

Nireco's laser marking system can mark directly onto the sides or ends of thick plates moving on the production line. It can write text information necessary for quality control and inventory management, and barcodes that are essential for logistics management, yielding major cost reductions.
Using our abundant experience and expertise in the steel industry, this marking system marks quickly and accurately, on hot metal or on cold metal. It is also highly environmentally stable, for dependable long-term use.

  • Handles all surface states.
  • Writes on all casting surface irregularities.
  • Harmless, water-soluble ink.
  • Newly-developed surface coat application nozzle eliminates ink blockages.
  • Low laser marker running cost - just surface coat and electricity.
  • High printing speed allows instant marking.
  • Prints regular, 2D, RSS and other types of barcode.
  • Prints on hot materials at up to 900°C, as standard.
