Laser marking applications
Marking character strings (such as dates and serial numbers)
Laser light is used to mark character strings such as dates, serial numbers, manufacturing numbers, and models directly onto a product. The advantages of laser marking include permanence, flexibility, and reduced running costs. Laser marking makes it possible to mark clearly on different shapes, even those with curved or contoured surfaces.
2D code marking
Laser light is used to mark data matrices, QR codes, barcodes, and more. As the need for better traceability increases, marking 2D codes is a great way to fit more information into a limited space. Laser marking can be done through black-annealed marking and white marking, making it possible to create a high-contrast code that is easily readable by code readers.
Data can be imported to the software, which instructs the laser to mark various designs such as logos and warnings. With conventional marking methods, printing and labeling made it difficult to change printed content when changing designs, and ever-increasing running costs such as for ink and labels were unavoidable. Laser marking offers flexibility for changing designs, as well as virtually no running costs.
Laser marking principles
Laser marking is used for marking logos, product names, serial numbers, model numbers, and other information onto a product by irradiating the target with laser light to melt, scorch, peel, oxidize, cut, or discolor the surface.
Laser markers can be used to perform various marking tasks, including the following.
|Paint peeling||Surface peeling||Color development|
|This method provides contrast against the base material color by peeling the paint, printed surface, or plating layers of a target for marking.||The surface of a target is removed, marked, or engraved in some way. This method is generally referred to as engraving.||The surface of a target is scorched, oxidized, or discolored by the laser light, resulting in a high-contrast mark.|
