In theLaser pointer process, because of the combination of melting and evaporation ablation, marking can be performed. The irradiance of the laser beam is so high that the material melts and partially evaporates during processing. Laser engraving will create depressions in the material. The typical engraving depth is 10 to 50 μm. The melt on the edge material is driven out by the vapor pressure of the evaporated material and solidifies as the edge of the melt when cooled. The engraving is U-shaped. As the laser cuts deeper and deeper into the material, the engraving becomes narrower and narrower because the melt cannot be completely discharged. The heat input is greatly restricted-locally restricted by small laser spots and extremely short pulses in time.
Portable marking solutions Laser marking and portable inkjet printers are key players in many devices in the marking industry. This article will help its readers understand how these two devices work and how their output differs. Understanding these aspects is critical to distinguishing the uses of these machines and choosing the right technology for the task. We will also study the features provided by manufacturers to improve the efficiency and usability of these devices. By the end of this article, readers will also learn about current applications. In addition, a brief price comparison of several leading market equipment can help users grasp the price points of portable laser engraver and ink marking machines in the industry.
Laser engraving is the process of evaporating materials into smoke. The laser beam acts as a chisel, scoring by removing the layer from the surface of the material. The laser must strike a local area with a large amount of energy to generate the high heat required for vaporization.
In this article, you will find in-depth information about how laser engraving works. But first, this is a short video showing the actual process of laser engraving. In this video, you will see the high-quality contrast, marking speed and the smoke generated during the marking process.
The laser cutting machine uses a laser beam to cut a flat material of a predetermined shape or pattern into thin slices. The process of deleting parts to create a product is called subtractive manufacturing.
Before operating the laser cutting machine, you must create the required design in the computer so that the selective laser beam knows where to cut. This process is usually very simple, even if you are creating a complex design, you do not need professional programming knowledge.
These machines can also perform blue laser pointer or etching, which includes laser cutting, which does not penetrate the material completely, but is deep enough to leave visible marks on the surface. The laser engraving machine can work on fragile materials (such as glass) without breaking or damaging the material below. Laser etching and engraving can be performed separately from manufacturing laser-cut objects.
