01 Laser Texturing of Aluminum Alloy Skin for Metro & Trains
It is mainly used for pre-treatment before bonding of aluminum alloy skins on metro and train bodies. Adopting laser technology, it simultaneously removes grease and oxide films and textures bonding surfaces, fully replacing traditional mechanical grinding and chemical cleaning processes.After treatment, the dyne level reaches 50 dyn/cm, and the surface roughness is raised from the original Ra 0.8 μm to Ra 2.0 μm, which greatly enhances adhesive bonding strength.
