Why UV lasers can mark black on plastic
Dec 07 , 2023
Why UV lasers can mark black on plastic When a UV laser irradiates plastic, it causes its surface to turn black. The reason behind this phenomenon is that the laser emitted by the ultraviolet laser has high energy, which triggers a photochemical reaction when it hits the plastic surface. The energy of ultraviolet laser can break the chemical bonds in the plastic molecules, causing the...

How does a laser marking machine print a white material barcode on plastic?
Dec 08 , 2023
How does a laser marking machine print a white material barcode on plastic? First, we need to understand how the laser marking machine works. Laser marking machines leave marks on the surface of the material by irradiating a high-energy-density laser beam onto the surface of the material. In this process, the laser beam scans the surface of the material. By controlling the switching and movement o...
