Laser cleaning and texturing technology are widely used in multiple fields, including automobiles, construction, home appliances and electronics, light industry and national defense, due to its advantages of high efficiency, precision, flexibility, reliability, stability, no loss, automation and high safety. Laser texturing technology can improve the surface finish, wear resistance, corrosion resistance and other properties of the object, create specific patterns or textures on the metal surface, and be used in material processing, surface modification and other situations. In the lithium battery industry, laser cleaning can remove impurities on the surface of the battery cell to ensure the reliability of the welding process, while laser texturing can increase the surface roughness and improve the strength of welding and bonding, thereby improving the overall quality and consistency of the battery.
Working principle of laser texturing
Laser texturing is a process in which the surface of an object is treated by laser technology to form a surface feature with tiny particles or hairy structures. Through the action of the laser beam, part of the surface of the object is melted to form tiny particles, and a hairy structure is formed after rapid cooling and solidification.

Application areas of laser roughening process
- Automotive industry: In the application of thermal coating cylinders, laser roughening can ensure a strong bond between the coating and the substrate, improving the efficiency of internal combustion engines.
- Home appliance manufacturing: In the production of home appliances such as refrigerators and washing machine shells, laser roughening can not only improve the coating adhesion of the shell, but also improve the appearance and texture of the product.
- Paint bonding: In some demanding coating fields, such as spacecraft and aviation equipment manufacturing, laser roughening can improve the quality and durability of the coating and avoid coating peeling in harsh environments.
- Medical devices: In the medical industry, laser roughening can improve the surface properties of medical devices, for example, by creating micro-textures on the surface of implants to promote bonding with human tissue.
- Semiconductor and electronics industry: Laser roughening can be used for fine processing of circuit boards or component surfaces to achieve specific electrical properties or improve their bonding ability with other materials.
- Surface design and decoration: Laser texturing technology can be used to create exquisite patterns and designs in the fields of metal jewelry and accessories to meet personalized decoration needs.
