There are four basic processes of laser engraving used in industry: Laser Engraving, Laser Removing Layer, Laser Bonding, and Carbon Migration. One of the top industries that use laser engraving is barcode marking. This process involves surface etching a barcode on metal (or other material)with a fiber laser that removes about .001" of material. Another use in industry for laser engraving is serial number marking which involves a laser removing layer to produce a serial number on metal or other material. Serial numbers can be engraved at depths of .003" or greater.
Company logos and signs can be laser engraved on wood, acrylic, marble, plastic or fabric. The automotive industry uses fiber laser engraving on auto parts. The laser bonding technique can be used to provide a contrast in color when used on black plastic auto parts so that the engraved letters or numbers can be seen more clearly. Carbon migration can be used for no contrast on black plastic.
