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. Laser markers engrave using short pulses (10’s-100’s of nanoseconds), providing precise control, and negligible heat input to the part.
A fast and clean technology, laser engraving is rapidly replacing older marking methods like dot peen and chemical etching. A key factor its 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, the fact that it is a non-contact process, improved environmental profile, and low cost of ownership add to the benefits of purchasing and using laser markers or laser etching equipment.
