Shenzhen radium UV ultraviolet laser marking machine is developed by 355nm ultraviolet laser. compared with infrared laser, the machine adopts third-order intracavity frequency doubling technology. the 355 ultraviolet light focusing spot is very small. the marking effect is to directly interrupt the molecular chain of the substance through short wavelength laser, greatly reducing the mechanical deformation and thermal deformation of the material (belonging to cold light), and can carry out ultra-fine marking. the minimum character can reach 0.1MM, mainly used for ultra-fine marking, engraving, especially suitable for food, pharmaceutical packaging materials marking, micro-hole, glass PCB identification, high-speed division and silicon wafer for complex graphics cutting and other application industries. Ultraviolet laser is a high-power multi-mode laser diode pumped to produce a laser and then double the frequency of the ultraviolet laser beam, and then through the computer control high-speed scanning galvanometer deflection to change the laser beam optical path to achieve automatic marking.
There are 1.5 watts, 3 watts, 5 watts and 10 watts in front of Shenzhen radium. the market has more power, and the higher the power, the higher the price. 1.5-5W UV equipment is mostly used in precision marking above, the greater the power, the wider the scope of application!
Matters needing attention when selecting UV laser marking machine:
1. Whether the output power of the laser is large enough (this is the key to speed and effect) and whether the energy is stable (usually 2% stability is required, and 1% is required in some occasions, so as to produce the ideal effect);
2. Laser output good beam quality, including mode and mode stability;
The laser should have high reliability and should be able to work continuously in harsh industrial processing environments;
4. The operation is simple and convenient, the control key function is clear, can refuse illegal operation, protect the laser from damage.
The laser itself should have good maintainability, fault diagnosis and chain function, and short downtime;
6. Shenzhen radium laser to provide free proofing services.
Scope of application:
Nowadays, with the rapid development of laser equipment and the improvement of the power of ultraviolet laser marking machines, ultraviolet laser marking machines have been applied to the high-end market of ultra-fine processing, marking the surface of packaging bottles of 3C electronic communications, cosmetics, medicines, food and other polymer materials. Flexible PCB board marking and scribing; Microhole and blind hole processing of silicon wafer; LCD liquid crystal glass, glassware surface, metal surface coating, plastic keys, electronic components, gifts, communication equipment, building materials and other fields.
