Characteristic of UV laser marking machine
Characteristic of UV laser marking machine.
technology are developed, laser marking machines are getting popular in the world.
UV laser marking machine is one type of laser marking machine. Main feature is 355 nm UV laser source.
Compared with infrared laser, UV light has very small spotlight, which can reduce the material mechanical deformation to a large extent and produce just a little processing heat.
UV laser marking machine are used for ultra-fine marking and carving.
Marked for food, pharmaceutical packaging materials, glass material , silicon Chip wafers, etc.
For the super tiny focusing UV light spot and very small area affected by heat processing.
It can be used for ultra-fine marking, special material marking.
The preference for customers who has higher demand for marking. UV laser is more widely used.
- Better beam quality and smaller focusing spot.
- Can achieve ultra-fine mark.
- The scope of application is more extensive.
- Does not produce thermal effect.Will not produce material scorching problem.
- High mark speed, high efficiency.
- Stable, small size, low power consumption.
Working Principle Details:
The working principle of UV laser marking machine is similar with common laser marking machine.
They make permanent marks on a variety of different material surface by using laser beam.
The marking effect is to expose the deep matter by evaporating the surface material, or to “mark” the trace by the chemical and physical changes of the surface material caused by the light energy, or to burn some of the surface material by light to show patterns and text.
UV laser marking machine with the main feature of unique low-power laser beam, is suitable for the ultra-fine processing of high-end market.
The marking surface of package bottle made from polymer materials for cosmetics, pharmaceuticals and food.
The effect is elaborate, marking is firm and clean and has no pollution.
Used in marking flexible PCB board, silicon wafer
Blind hole processing.
Two-dimensional code for LCD glass.
Glassware surface drilling
Metal surface coating
Electronic components, gifts.
Building materials …
The reason that the UV laser processing is cold processing is the high-energy molecules of ultraviolet photons.
directly break away the molecules from metal or non-metallic materials needed to marked.
This lead to the separation of molecules from the material and this processing will not produce heat.
Not producing heat is the main difference between the traditional laser marking machine and UV laser marking machine.
