At the same time, the surface is also cleaned and sulfid es removed during this process. High contrast and dark black in color Permanent, corrosion-resistant and non-fading dark marks Machine readable Shallow surface relief so as not to retain bacteria No passivation step required after marking Black laser marking is most often used in the medical device industry in order to meet UDI (unique device identification) requirements.
REBASLIGHT MAKING A BLACK LASER FREE
free iron ions) from the surface, and supports the clean, fast formation of a new chrome oxide film for even better corrosion resistance. In this process, an acid bath consisting of saltpeter or citric acid removes highly reactive elements (e.g. You can change the color or size using the controlls on the left. To preview your work click the button on the far right. After clicking on a point, you can hold down the ctrl key use arrow keys to move it 1 pixel at a time. Right click (or ctrl+click) to remove them. This is why a targeted passivation procedure is often opted for when it comes to refinishing. From the menu select Effects > Laser Glow. Compared with the common fiber laser source, the Mopa fiber laser source has a special function that it. Yes, this is the key that makes it could laser mark & engrave black color on anodized aluminum materials like iPhone case and iPad case. The legibility and durability of laser marking can be affected by prolonged exposure times, aggressive cleaning agents, or high temperatures. A Mope fiber laser marking engraving machine is a laser marker engraver with Mopa fiber laser source.
The microstructured surface ensures that light scattering is reduced, and creates a marking with constant depth and a. Extremely short laser pulses cause structures on the surface at the nanometer level. This is why it is referred to as "cold processing". Black marking is a procedure in laser processing which causes extremely dark, high-contrast markings on a surface without material ablation. This prevents thermal stress cracks which can occur in conventional annealing when the parameters are not considered. This is because the laser pulse, and therefore the duration of the energy input, is so short that temperature transport to neighboring atoms does not even occur. It becomes possible to process materials with virtually no thermal or mechanical impact.
