FIBER LASER TECHNOLGY

Principle & Characteristics

Fiber laser marking is a technique which uses computer-controlled laser beam to leave permanent mark on the surface of various kinds of object. The working principle of fiber laser marking machine is to use light amplication to cause chemical effect or burn part of the material to mark letters, symbols, bar codes, and other graphics on an object.

Fiber laser marking machine is mainly composed fiber laser, laser scanning galvanometer and controller. The fiber laser has the advantages of small size, high quality beam, no maintenance and etc. The output center wavelength of fiber laser is 1064 nm and the life time is around 100,000 hours. Compared with other king of lasers, fiber laser has a long life.

Advance Features
1. Can mark both metallic and nonmetallic materials, especially those materials with high hardness, high melting point or brittle materials.
2. High processing speeds, low operation cost, constant high quality and durability of the results, high flexibility in automation. Laser marking is a perfect choice for mass production.
3. Laser marking is non contact type of marking so it doesn't produce stress on the materials. It will not alter the physical properties of the materials processed.
4. Laser is a clean and safe process as it is chemical-proof, water-proof, oil, grease & fuel proof.
5. As the laser beam spot size (after focusing) is small, the heat-affected zone is much smaller, thus allowing it to achieve fine processing that other conventional methods cannot.
6. Laser Marking is a flexible process as one can mark texts, alphanumeric, logos, bar codes, graphics, images, 2D data matrix code, etc.
7. It is a user-friendly and cost effective marking solution as virtually no consumables.
8. Laser marking enhances the aesthetical & monetary value of products by making it more attractive & eye catching

Applications
Laser marking machine is widely used in most kind of products in different industrials, such as integrated circuit chip, computer accessories, industrial bearings, watches and clocks, electronic and telecommunication products, aerospace parts, auto parts, home appliances, hardware tools, molding, wire and cable, food packaging, jewellery, and etc.
