Co2 common wavelengths are 10.6μm/10.2μm/9.3μm, the main applications are suitable for non-metallic materials, due to special materials for a certain wavelength has a stronger absorption properties or better results, then confirm the specific wavelength of the co2 laser marking machine is more suitable for a certain product or a certain material.
Co2 10.6μm is relatively common. Due to the longer wavelength, its energy is larger, making it highly suitable for cutting and processing many non-metallic materials. This wavelength is widely used in wood laser printers and various laser printing on plastic applications.
Co2 9.3μm is a relatively less used laser, due to its higher material requirements, so only a small number of materials are currently using the co2 9.3um laser. PET plastics have a better effect on this 9.3um wavelength laser marking machines, the surface will have a frosted texture and more recognizable effect, compared to the co2 10.6/10.2um, it is more recognizable. Due to the shorter wavelength, the corresponding energy will be smaller, the heat affected zone HAZ is smaller, so for other materials, theoretically, the 9.3um processing precision is higher, the edge is smoother, and the deformation is smaller.
Features/Applications | HC20XXB 10.6um | HC20XXB 9.3um |

Advantages of HND LASER | HC2040B This device will drastically reduce the 10.6/9.3um price gap and further reduce the cost of 9.3um lasers. | |
Polyethylene terephthalate (polyethylene terephthalate, or PET or PETE for short) is very suitable for food packaging due to its high toughness, light weight, impermeability, resistance to acid and alkali, water and oil. The modified high-temperature resistant CPET can even be made into high-temperature resistant containers, such as bowls and pots, cups and cutlery.
Bottled water beverage industry commonly used PET as the main container, 9.3um is the most used in this industry, the general logo contains the date of production, batch number, generally only 1 line or 2 lines of content, individual countries or regions need to be 3 lines or 4 lines, individual need to be identified in the bottle price above.
Ordinary 10.6um laser, in the PET bottle marking is translucent effect and clear melting boundary, need to be close to see the content. But the effect of 9.3um will be very significant, white frosted effect is presented on top of the transparent PET bottle, the contrast effect is very clear. According to the test 9.3um laser can be easier to mark on PET bottles, PET for 9.3um absorption rate is better, can be adapted to the production line speed higher production line. Because 10.6um has burn and mark on plastic, which affects the thickness of bottle, so we won't use 10.6um laser for aerated beverages, 9.3um is more suitable for aerated beverages.
