Principle of paint stripping by UV laser marking machine

The principle of UV marking machine peeling paint is to position the laser beam to the processing surface, causing the surface to instantly heat and expand, forming tiny holes. These holes gradually expand and eventually lead to the peeling off of the paint layer. Specifically, laser irradiation causes thermal expansion and cold contraction peeling of the surface paint layer, which may be accompanied by high-intensity vibration, causing the peeled paint layer to be directly crushed. This process requires no consumables and only requires electricity to drive, so it is environmentally friendly, convenient and fast.

Application fields of laser paint stripping 

UV marking machine paint stripping technology is widely used in many fields, especially in the electronic and electrical industry.
For example, when welding conductors, it is usually necessary to peel off the paint layer on the outside of the enameled wire.
UV marking machines can complete this task efficiently and accurately. In addition, this technology is also used in scenarios such as paint stripping of magnetic head coils, connection of circuit inductor coils, and paint stripping of various enameled wires.
At the same time, with the development of technology, UV marking machines are gradually being used for stripping paint of metal spray coatings, plastics and other materials.

Advantages of laser paint stripping 

1. **High Precision**: The UV marking machine can achieve high-precision paint stripping processing, ensuring precise control of the paint stripping area and avoiding unnecessary damage to the surrounding area.
2. **Non-contact processing**: Compared with traditional physical and chemical paint stripping methods, UV marking machines adopt non-contact processing and will not cause mechanical damage or chemical corrosion to the processed materials.
3. **Environmental protection and energy saving**: No need to use any chemical reagents and drugs, avoiding the resulting environmental pollution and damage. At the same time, it only needs electricity to drive and the energy consumption is relatively low.
4. **Efficient and Fast**: High degree of automation, which can significantly improve paint stripping efficiency and work efficiency, and reduce labor costs.
5. **High flexibility**: The power, scanning speed, frequency and other parameters of the laser can be adjusted according to the characteristics of different materials and paint stripping needs to achieve the best paint stripping effect.
