Should I use 9.3um or 10.6um for laser cutting of PET?

When choosing to use laser to cut PET, we usually choose to use CO2 laser for cutting, but many people don鈥檛 know that there are many different options for CO2, such as 9.3um and 10.6um band CO2 lasers. So when we cut PET, which band of laser would be more suitable? The following are some reasons why our editor of Laisei Laser recommends 9.3um band lasers.

鈻?Absorption characteristics:

PET material has a high absorption rate under the 9.3渭m band of carbon dioxide laser. This means that PET can effectively absorb the laser energy of this wavelength, making it easier to cut.

鈻?amp;nbsp;Small influence of moisture:

Compared with 10.6渭m band, 9.3渭m band CO2 laser has less influence on the absorption of water molecules. Therefore, when cutting in an environment or on materials containing moisture, 9.3渭m laser can operate more stably to avoid affecting the cutting effect due to moisture interference.

鈻?amp;nbsp;Cutting effect:

PET cutting using a 9.3渭m band carbon dioxide laser usually produces better cutting results. This wavelength can effectively penetrate PET materials and produce high-quality cut edges, and can reduce thermal effects on surrounding materials, reducing charring and melting on the cut edges.

Although 10.6渭m CO2 lasers can also be used for PET cutting, generally speaking, the 9.3渭m band is more suitable for this application because it can provide more effective cutting results and a more stable operating environment. Choosing the right band also depends on the specific cutting requirements and equipment availability, so it is recommended to select and test according to actual conditions.
