The full name of PVC is Polyvinylchlorid. The main ingredient is PVC, which is a synthetic material that is popular and popular in the world. I believe that everyone knows how close the PVC is from our lives. It is no longer strange. In short, it is a component of a plastic product.
PVC materials are polyvinyl chloride, one of the world’s large-scale plastic products, cheap, wide application, PVC material has light, insulation, moisturizing, moisture-proof, flame retardant, simple construction, etc., specifications and color patterns There are many styles, extremely decorative effects, generally PVC water pipes, PVC plastic doors and windows, and plastic toys containing PVC. Next we analyze the common models for the PVC laser marking.
In general, the currently marking of the PVC material is to use near infrared lasers or far infrared lasers (than the CO2 laser), and the far-infrared laser marking machine is common is a carbon dioxide laser marking machine, which wavelength of this laser It is 10.6 μm, which can make Yellow-Chi colored handwriting on PVC data, because the function of carbon dioxide laser can be large, more than 30W power marking machine and 50W power marking machine, so This type of marking machine can be marked with a very high speed, which is ideal for processing on the pipeline, replacing the ink coding that is not very environmentally friendly.
However, the carbon dioxide laser marking machine is not so popular, but near-infrared laser computes fiber laser marking machine and semiconductor laser marking machine, the wavelengths of them are at 1060nm This wavelength can be marked with black, this black image of the black and ink symptom, is a color that allows customers to accept, and this type of marking is increasingly used on PVC material. .
The wavelength of the fiber laser is 1060 nm, which can be clearly engraved on the PVC material, and showed a significant black, and the fiber laser is considered to be a laser that replaces the semiconductor laser, which is also the most waiting in PVC information. The fiber laser marking machine can reach 80K because of its frequency, the spot is small, and the mirror of the small spot can reach a very high speed, which can reach or exceed the CO2 laser speed at the speed of the tapping water line.
The fiber laser marking machine has extremely excellent beam quality, and is quaint, suitable for harsh environments, so PVC materials are more suitable for marking on fiber laser marking.
