Laser Marking, also known as ‘laser engraving’ or ‘laser etching,’ is a marking method which utilizes laser light to mark materials using a fine spot diameter ranging from 0.002′ to 0.01′. The laser marks with short pulses (30 nanoseconds), providing precise control, and negligible heat input to the part.
A fast and clean technology, laser marking is rapidly replacing older marking methods. A key factor in this widespread adoption is the exponential increase in the use of direct part marking to enable tracking and traceability across many industries, most notably medical device and automotive electronics manufacturing. Easy and flexible automation, improved environmental profile, and low cost of ownership add to the benefits of laser marking equipment or laser etching equipment.
