Laser is a device that emits a beam of coherent light through an optical amplification process. A laser can be considered as a system which stores light energy and releases it in a much localized area, the emitted energy has very high density energy. 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.

Laser marking stands for marking or labeling of work pieces and materials with a laser beam. It is the production of human- and/or machine-readable identification or information on a material such as barcode, date/lot code, serial number or part number, others. A fast and clean technology, laser marking is rapidly replacing older marking methods. The Global Laser Marking Machine Market is segmented on the basis of type of machine, applications, and region.
On the basis of type of machine, the global market is classified into Fiber laser marking machine, CO2 laser marking machine, End-pumped laser marking machine, Side-pumped laser marking machine, hybrid laser marking machine, laser engraving machine, UV laser marking machine, others. CO2 laser marking machine – is an ultrafine marking machine for non-metal marking. It incredibly imprints over glass, plastic, acrylic, and many other materials. Its crystalline marking works on wrappers and packages.
UV laser marking machine delivers high contrast, permanent codes allowing product lifetime track and trace for pharmaceutical, medical device and cosmetic manufacturers. Laser engraving machine, which is a subgroup of laser marking, is the practice of using lasers to engrave an object. A laser engraving machine usually consists of three main parts: a laser, a controller, and a surface. The laser is like a pencil, the beam emitted from it allows the controller to trace patterns onto the surface. On the basis of forms of laser marking, the global market is classified into Annealing laser marking, carbon migration laser marking, foaming laser marking, and coloration laser marking. Annealing laser marking – refers to an oxidation process of applying heat to a surface material. It is common in medical industry with applications such as internal tracking and branding.
Carbon migration laser marking – it can be applied to metal and metal alloys. Carbon migrates to the surface via a heating process which produces dark markings. Heat is applied at a rapid pace. It can be used in Aerospace, jewelry engraving, metal working, and others. Foaming Laser Marking – is used when a plastic is darker and the desired end result is a lighter color (usually white, gold or various tan shades). This change in color occurs by creating a molten burn on the surface that is both contained and controlled. When the surface is melted, it creates an atmosphere of foaming gas bubbles. Foam laser marking can be used for marking on ink cartridges, keyboards, cosmetic packaging, others.
Coloration Laser Marking – The process of adding color to a plastic or metal, or coloration laser marking, is created by heating specific parts of a surface based on the anticipated outcome. Modifying the surface by controlling its pulse frequency, width, and more will result in varying colors and shades. Metal coloration occurs with an oxidation process. It can be used in creating decorative jewelry, color coating ear tags for cattle, and marking colors on a bottle cap.
On the basis of materials, the global market is classified into Metals: Stainless steel, aluminum, gold, silver, titanium, bronze, platinum or copper, Plastics: ABS, polycarbonate, polyamide, PMMA or plastics with laser additives, Paints, Foils and films and packaging, Laminates. On the basis of technique, the global market is classified into photo masking and the beam steering.
On the basis of application, the global market is classified into high-speed characters, logos, graphics, bar codes, 2D Data Matrix marking. Geographically, the global market is segmented into North America, China, Europe, Southeast Asia, Japan, and India. The key players are, Telesis Technologies, Videojet, Epilog Laser, Tykma, Mecco, Laserstar, Universal Laser Systems, Gravotech, Rofin, Trotec, FOBA, Trumpf, Eurolaser, Keyence, Hans Laser, and Huagong Tech.
