Laser marking has certain requirements for the glossiness, thickness, and hardness of aluminum material surfaces.
Requirements for laser marking on aluminum material surface
During the laser marking process, factors such as glossiness, thickness, and hardness of the aluminum surface can all affect the marking results. Therefore, in order to achieve better marking results, we need to have a certain understanding of the requirements for the surface of aluminum materials.
1. Glossiness
The surface glossiness of aluminum can affect the energy absorption of laser marking and also affect the final marking effect. If the surface of the material is too smooth, the laser is prone to reflection during the marking process, resulting in poor results. Therefore, there should be some control over the glossiness of the aluminum surface, which can be treated by sandblasting, cutting, and other methods.
2. Thickness
The thickness of aluminum also affects the effectiveness of laser marking. Generally speaking, the thinner the aluminum material, the better the marking effect. However, if it is too thin, it is prone to problems such as burrs and burnt holes. Therefore, the thickness of aluminum needs to be selected and adjusted according to specific process requirements.
3. Hardness
The hardness of aluminum also affects the effectiveness of laser marking. If the hardness of the aluminum material is too high, it will be difficult for the laser to penetrate, affecting the quality of the marking. On the contrary, if the aluminum material is too soft, it will be easily cut by laser, resulting in a large cutting range. Therefore, before laser marking, it is necessary to measure and judge the hardness of the aluminum material.
Adjustment of laser marking parameters
According to different process requirements, the parameters of laser marking also need to be adjusted accordingly. For example, if it is necessary to mark dark aluminum, the power and frequency of the laser need to be adjusted to achieve better results. In addition, different marking contents also require setting different parameters. Developing suitable parameters can greatly improve the quality and efficiency of marking.
【 Conclusion 】
In summary, laser marking has certain requirements for the glossiness, thickness, and hardness of aluminum material surfaces. In practical applications, it is necessary to adjust according to specific process requirements and control the surface treatment of aluminum materials to achieve better marking results.
