Features of plastic laser marking

1. Integrated design, better meet the user's industrial production needs, small size, high space utilization.

2. The beam quality is good and the focus spot is small, which can realize ultra-fine marking.

3. The heat-affected zone is extremely small, no thermal effect occurs, and there is no problem of material burning.

4. Adopt built-in laser diode technology to avoid the influence of fiber jitter on the output laser.

5. This machine can be equipped with other optional accessories according to the customer's actual product laser marking requirements, such as rotating device, 2D/3D workbench, pen turntable and other fixtures.

Advantages of plastic laser marking

1. High marking precision, fast speed, clear text pattern, uniform and durable.

2. The heat-affected zone is extremely small, avoiding the deformation, damage or burning of the processed materials, and the yield is high.

3. Stable performance, no consumables, low cost of use, and maintenance-free.

4. The beam is excellent enough to ensure the stability and reliability of mass production and meet the special manufacturing and processing requirements under harsh industrial conditions.

5. It can be integrated on the production line to mark the production date, S/N number, etc.

6. Suntop fiber laser marking machine will go through strict aging test and 24 hours of continuous laser beam output before leaving the factory to ensure 100% stability of the machine.
