Product Details

Keyland 532nm Green Laser Engraving Machine

--- High Quality Laser Mark Machines

------Higher expectations of marking effect's first choice

Advantages

Focused UV light spot size is small , heat-affected area during processing is mimimum,

So it is used in ultra-fine and special material’s marking.

Since UV laser did not produce any thermal effects and burning issues, the result of the marking is precise , smooth and steep.

A lot of material will absorb UV light at 355nm except Copper, so UV laser are suitable for processing more types of material .

Applications
High-end ultra-refining market: cosmetics, pharmaceuticals, food and other polymer bottles’ surface. Marking effect is fine, clear and solid, which is better than the injekt printing and no pullution produced.

Also used in marking and dicing flexible PCB board, drilling tiny hole or blind-hole on silicon wafers, two-dimensional coding on LCD, glass container surface, metal surface coating, plastic keys, electronic components, gifts, communication equipment, construction materials

Principle
UV laser processing is achieved by photochemical ablation.

Strong energy of the laser can interrupt the bonding between atoms or molecules and transform them into small molecules. Small molecule is easy to evaporate.

Features

1.Excellent beam quality, smaller focused spot size, ultra-fine marking;

2.Since most materials can absorb the UV light, the range of application is much more wider;

3.Small heat-affected region, no thermal effects, no burning issue;

4.High speed, high efficiency;

5.Stable performance , small size, low power consumption.
