Eight Advantages for Laser Marking

Laser marking technology is more widely used in printing field in recent years and laser marking can be applied to several materials, for instance, plastic and rubber, metal and silicon chips. In comparison to the traditional mechanical engraving, chemical corrosion, network printing and oil ink printing, laser marking is characterized by low cost and high flexibility and can be controlled by computer system. The mark produced on workpiece surface by laser is permanent. Currently, in marking printing industry, laser marking has occupied 90% market, which may result from the following ten advantages:

1. Permanency: 
Marks will not be degraded due to the environmental factors (such as contact, acid or alkaline gas, high or low temperature, etc.) 

2. Anti-counterfeiting: 

The marks engraved by laser marking technology can not be forged or changed easily with strong anti-counterfeiting to certain extent. 

3. Non-contacting: 

Laser marking is made by non-mechanical “photo knife” and marking can be made on any regular or irregular surface. The marked workpiece will not produce internal stress, and the original precision of the workpiece can be ensured. It neither corrodes working surface nor wear “cutting tools” without any poison or pollution. 

4. Broad application:

Processing means of laser can be applicable to the processing of several metal and non-metal materials (such as aluminum, copper, iron and wooden products). 

5. High engraving precision:  

The articles engraved by laser marker are in fine and elegant patterns and the width of the smallest line can reach 0.04mm, with clear, lasting and elegant marking. Laser marking can satisfy the demand of printing plenty of data on very small plastic object, for instance, two-dimensional code with more precise requirements and higher definition. By comparing with impressing or spraying marking way, it has strong market competitiveness. 

6. Low operation cost: 

Marking speed is fast and marking can be made for once only but the operation cost is quite low. In spite of the larger investment of the laser marking equipment than the traditional ones, the cost of laser marker is very much lower from the perspective of operation costs. 

7. High processing efficiency 

Laser beam controlled by computer can be moved in high speed (the speed as high as 5~7 m/s) and marking can be finished within several seconds. 

8. Fast development speed 

With the combination of laser and computer technology, the user can realize laser printing output by programming through computer and can change the printing design at any time, which replace the traditional module manufacturing process essentially and providing convenient tools for shortening upgrade cycle of product and flexible manufacturing.
