Laser marking machines classification and benefits
According to different materials, different wavelengths of laser absorption of the different characteristics of the Laser marking machines generally divided into two categories, one is the use of YAG laser, suitable for processing metal material and most of the non-metallic materials such as iron, copper,aluminum, gold, silver and other metals and various alloys, and ABS material, ink coating, epoxy resin and so on.Another use of CO2 laser, can only process non-metallic materials such as wood, paper, acrylic, glass and so on.Some material also applies to two types of laser marking machine, but results have identified different processes.
YAGmarking machines, including lamp-pumped, semiconductor and optical three categories, CO2marking machines include two types of radio tubes and glass tubes, which constitute the five products, the standard model Laser marking machines.The actual needs of different users, together with the different shape structure, fixture tooling, customized software systems to form complete laser marking solution.
Relative to the pneumatic marking, electrical corrosion, screen printing, inkjet printer, marking machine engraving and other traditional methods, Laser marking machines has the following advantages:
1. Laser processing of optical contact, non-mechanical contact, no mechanical stress, it is particularly suitable for high hardness (eg, carbide), high brittle (such as solar silicon), high melting point and high precision (such as precision bearings) require specialsuch high occasions.
2. A large energy density of laser processing, the time is short, small heat affected zone, thermal deformation, thermal stress is small, does not affect the internal electrical performance.
3. Direct ignition laser etching, as a permanent marker, indelible and will not fall off failure deformation, suitable for security anti-Cuanhuo, and product traceability requirements.
4. Laser processing system itself is a computer system can be easily arranged, modified, there is dancing, random code and other functions, the only coding required to achieve product suitable for individual processing of small batch processing of multiple batchesadvantage.
5. Effect of laser marking machine marking fine, craft beautiful, high accuracy, can enhance product quality, increase product added value.
6. Linewidth can be as small as 10μm, the depth of up to 10μm below, may be on the "millimeter" size of the part surface marker.
7. Low supplies, pollution, environmental protection, in line with European environmental standards, in line with GMP requirements of the pharmaceutical industry.
8. Processing costs low.One-time investment in expensive equipment, but continuous, a large number of processing ultimately reduce the cost of each part of the process down.
