All kinds of principle of laser marking machine is introduced
by：LEAD TECH 2020-05-04
Common are laser marking machine, fiber laser marking machine uv laser marking machine, CO2 laser marking machine, for their own use and the principle of suitable for different so they are also different.
Carbon dioxide CO2 laser marking machine: using CO2 gas filling the discharge tube as a medium, to create the laser extensions on the electrode voltage, discharge tube of glow discharge, causing the gas molecules release laser, the laser energy amplification to form for laser material processing.
Optical fiber laser marking machine: output directly by the fiber laser, electro-optic conversion efficiency is high.
Ultraviolet laser marking machine: with electro-optical conversion rate is high, long service life, nonlinear crystals the machine running stability, high positioning accuracy, high efficiency, modular design easy installation and maintenance, etc.
Uv laser marking machine configuration deep ultraviolet laser, imported high-speed scanning galvanometer system, etc. ;
Due to ultraviolet laser marking machine is focused on the minimal flare, and processing and heat affected zone small, thus ultraviolet laser marking machine can undertake hyperfine marking, special material marking, ultraviolet laser marking machine is rally marking effect have higher requirements of customers preferred products.
Different laser marking machine marking out the effect is also different, for example: fiber laser marking machine 1, for a variety of metals, non-metallic materials for processing.
Especially for high hardness, high melting point, brittle materials are marked more advantage.
2, belong to non-contact processing, no damage to the product, no tool wear, tags are of good quality.
3, fine laser beam, and machining materials consumption is very small, small heat affected zone.
4, high processing efficiency, using computer control, easy to realize automation.
Ultraviolet laser marking machine: fine machining of adaptation in high-end market in particular, cosmetics, medicines, food and other packaging bottles of marking on the surface of polymer material, fine effect, marks a clear and firm, is better than that of printing ink and pollution-free;
The flexible PCB marking, scribing;
Porous silicon wafers, blind hole processing;
LCD glass qr code marking, punching, metal surface coating glassware surface marking, plastic buttons, electronics, gifts, communications equipment, building materials and so on.
