A MOPA FIBER LASER MARKING TESTING ON PE MATERIAL

2020-05-25
61 times
We used five main parameters to adjust the marking effect on the black plastic(PE) with MOPA fiber laser marker. They are “speed”, “frequency”, “power”, “fill distance” and “mode”. One of the advantage of our machine is that it has multiple mode(Pulse width)—8 in total, compared to other fiber laser source with only one mode.
 
In this report, we test four parameters and marked the letter “A” on the material. To test, we change one specific parameter with 8 different values while keeping the other four parameters unchanged.



—— Test 1 ——

Speed: 300 mm/s, Power: 8%, Mode: 1, Fill: na

Frequency(Variable): 5khz, 25khz, 50khz, 100khz, 300khz, 500khz, 750khz, 1000khz

                                           
The following pictures are observed under microscope(50 X). Order from left to right for letters pointed by arrows in the picture above.

  
                           
 25khz                                                        100khz                                                           1000khz




 
——  Test 2 —— 

Frequency: 30khz, Power: 8%, Mode: 1, Fill: na

Speed(Variable): 75 mm/s, 125 mm/s, 200 mm/s, 300 mm/s, 400 mm/s, 600 mm/s, 1200 mm/s, 2400 mm/s
                                                           
The following pictures are observed under microscope(50 X). Order from left to right for letters pointed by arrows in the picture above.

 
  
                         
75 mm/s                                                   600 mm/s                                                 2400mm/s




 
—— Test 3 ——

Frequency: 25khz, Power: 3%, Mode: 1, Speed: 1000 mm/s 

Fill distance(Variable): 0.2 mm, 0.1 mm, 0.08 mm, 0.06 mm, 0.04 mm, 0.03 mm, 0.02 mm, 0.01 mm

                                                      

The following pictures are observed under microscope(50 X). Order from left to right for letters pointed by arrows in the picture above.

  

                      0.2mm                                                            0.06mm                                                    0.01mm   



 

—— Test 4 —— 

Frequency: 35khz, Power: 10%, Speed: 250 mm/s, Fill: na

Mode : 1, 2, 3, 4, 5, 6, 7, 8

                                 

The following pictures are observed under microscope(50 X). Order from left to right for letters pointed by arrows in the picture above.
