The classification of laser marking machine

According to different material, different wavelength laser absorbing different characteristic, Laser Marking Machine is usually assorted into two major kinds:. One is the use of YAG laser marking machine, which is suitable for processing of metal material and majority of non metallic materials such as iron, copper, aluminum, gold, silver and various alloys, and ABS material, ink coating, epoxy resins and so on. The other kind is using CO2 Laser marking machine, which can only process non-metallic materials such as wood, paper, acrylic, glass and so on. Some of materials can apply to the two types of laser marking machine at the same time, but identification process result is vary.

YAG Laser Marking Machine including lamp pump, diode pump and fiber optic laser marking machine, CO2 Marking Machine including two major categories of radio-frequency tubes and glass tubes, and the five products constitute the standard models of laser marking machine. According to the actual needs of different users, coupled with a different shape structure, fixture tooling, customized software systems to form complete laser marking solution.

Relative to the traditional form of marking such as pneumatic marking, electrical corrosion, screen printing, inkjet printing, mechanical carving, laser marking machine has the following advantages:

1. laser marking is light contact, non-mechanical contact, having no mechanical stress, which is especially suitable for occasions with super high requirements such as high hardness( such as carbide), high brittle( such as solar silicon), high melting point and high precision( such as precise bearings).

2. Laser marking is high energy density, short time, small heat- affect area; small hear distortion, small thermal stress, which doesn’ t affect of internal electrical performance. the cold processing of 532 μm，355μm，266μm laser marking machines, in particularly, are suitable for precise processing of special materials.

3. Laser Marking Machine is direct ignition etching, belonging to permanent mark, which cannot be erased, deformed, distorted and fallen off, suitable for anti-counterfeit, and realize the need of product traceability.

4. Laser marking machine system itself is a suit of computer system, which is convenient to do facilitation, modification, and has dance number and random code functions, realizes the only coding requirement, suitable for individual processing, and has more advantages for small amount and multi-batch process.

5. Fine mark result, beautiful craft, high accuracy, laser marking machine processing can improve product grade and added value of products.

6. Line width can be as small as 10μm, the depth up to 10μm below, the laser marking machine can mark on surface of millimeter level parts.

7. Low material consumption, no pollution, energy saving and environmental protection, meeting the Europe environmental standards and the GMP requirement of pharmaceutical industry.

8. Low processing cost. The up-front payment of Laser Marking Machine is much higher, but continuous, significant amount processing can finally reduce the processing cost of each parts.

9. Flexible processing. Laser marking machine can process internal workpiece through transparent medium, which is easy to orient, focus, and realize direction change and easy to cooperate with CNC.
