Fiber laser marking machines have excellent beam quality, and are compact and suitable for harsh environments, so PVC materials are more suitable for marking on fiber laser marking machines.
PVC material is polyvinyl chloride. It is one of the largest plastic products in the world. It is cheap and widely available. PVC material is light in weight, comes in various specifications and color patterns, and is very decorative. Generally, there are pvc water pipes and pvc plastic doors and windows and plastic toys that contain pvc. So which laser marking machine is more suitable for marking PVC materials?
Generally speaking, near-infrared lasers or far-infrared lasers (such as CO2 lasers) are currently used for marking on PVC materials, and far-infrared laser marking is the most common mark. This machine is a carbon dioxide laser marking machine. The wavelength of this laser light is 10.6 μm. This type of marking machine can print yellow and red handwriting on PVC materials, because the function of the carbon dioxide laser can be very powerful. Therefore, this type of marking machine can mark at a very high speed, which is very suitable for processing on the assembly line.
However, the carbon dioxide laser marking used to mark PVC materials will appear yellow-red, so it is not very popular, while the wavelength of fiber laser marking machine and semiconductor laser marking machine is 1060nm, and the wavelength will be marked as black. This black is similar to the black of an inkjet printer, which is a color acceptable to customers. Such signs are increasingly used on PVC materials.
The wavelength of the fiber laser is 1060nm, which can clearly mark on the PVC material and show a very obvious black color. Fiber lasers are considered to be a laser that replaces semiconductor lasers, and their application prospects on PVC materials are also long-awaited. Since the frequency of the fiber laser marking machine can reach 80K, the spot is very small, and the galvanometer with a small spot can reach a very high speed. It can reach or exceed the effect of CO2 laser on the marking line speed.
Fiber laser marking machines have excellent beam quality, and are compact and suitable for harsh environments, so PVC materials are more suitable for marking on fiber laser marking machines.
