As the global manufacturing industry places increasingly stringent demands on environmental protection, efficiency and precision, laser cleaning—an innovative non-contact, pollution-free and high-precision surface treatment technology—is ushering in a green revolution for the traditional wood products industry. Studies have shown that precise control of laser parameters (e.g., wavelength, power, pulse width) enables the effective removal of contaminants such as paint, glue, stains and mold from wood surfaces without damaging the wood substrate. This technology is particularly suitable for the restoration of exquisite wood veneers, complex carved components and cultural relics. Additionally, laser surface treatment can be applied to wood surfaces to alter their color, improve surface wettability, enhance the performance of surface coating materials, and boost anti-corrosion and anti-mold properties. Looking ahead, with the integration of intelligent technologies such as beam shaping, ad
The ink blocking the cells affects the printing quality, which is a pain point that the flexo printing industry has been difficult to solve. The anilox rollers that have been working for a long time, in addition to part of the damage caused by wear and tear, will also be scrapped due to the reduced cell volume, which affects the printing efficiency and quality. Deep cleaning at least 1-2 times a year will restore the anilox roller as new, prolong the service life of the anilox roller, improve printing quality, and reduce ink loss.
Achieving stable, high-quality laser cutting depends on more than just power, speed, or focus settings. One of the most easily overlooked yet crucial factors is coaxial alignment—the alignment of the laser beam center with the nozzle center. Poor coaxial alignment can lead to inconsistent cuts, excessive slag, kerf offset, and even frequent nozzle damage.
The wavelength of a laser describes the spatial frequency of the emitted light wave. The optimal wavelength for a particular use case depends largely on the application. In material processing, different materials have unique wavelength absorption characteristics, leading to different interactions with the material. Similarly, atmospheric absorption and interference affect certain wavelengths differently in remote sensing, and in medical laser applications, different skin tones absorb certain wavelengths differently. Due to their smaller focused spot size, shorter-wavelength lasers and laser optics have advantages in creating small, precise features with minimal peripheral heating. However, they are typically more expensive and more susceptible to damage compared to longer-wavelength lasers.
