How to use a UV laser to mark a QR code on a plastic round tube

The process of marking a QR code on a plastic round tube with a UV laser is as follows:

1. Preparatory work: Make sure that the UV laser and marking equipment are working normally, and have parameter settings suitable for marking plastic round tubes.

2. Prepare the plastic round tube: Make sure the surface of the plastic round tube is clean and free from dust or stains. If necessary, wipe the surface with detergent or alcohol.

3. Set the marking parameters: according to the size and requirements of the two-dimensional code to be marked, set the parameters such as the power, frequency and marking speed of the ultraviolet laser. The selection of these parameters should be determined according to the specific plastic material and marking equipment.

4. Marking operation: place the plastic round tube on the marking device and make sure it is fixed. According to the set parameters, start the UV laser for marking operation. The ultraviolet laser will generate a high-energy ultraviolet beam on the surface of the plastic tube, and form a two-dimensional code on the surface through a photochemical reaction.

5. Inspection and quality control: After marking, check the quality and clarity of the QR code. If necessary, quality control and adjustment of marking parameters can be carried out to ensure the readability and durability of the 2D code.

Please note that the specific operation steps may vary with different marking equipment and UV lasers. Before marking, please make sure you are familiar with the operating instructions and safety procedures of the equipment.
