Laser marking can be performed on metals using the following laser marking techniques. Each technique marks a specific feature; hence they have specific functions. Below are the common laser marking techniques in relation to metals and their characteristics.
In laser annealing, the laser marker generates a laser beam, which heats the surface where marks appear due to oxidation. The surface gets its colored appearance because of the composition and thickness of the oxide layer.
This laser marking method removes coating or lacquer layers from the base material. For example, the ablation of the oxide layer of anodized aluminum exposes the metal beneath it. Due to the high temperatures ablation markers produce, they heat the surface past its vaporization point. While not damaging the base material, your marking pattern or text is visible.
This laser marking technique changes specular reflection by removing material from the surface. It mostly applies to metals. There is an optimal frequency and speed so that evaporation can occur for the material. Laser markers with short pulses and high peak power generally give the best results and are best suited for these applications.
There are three techniques when marking a plastic material. They include
In laser foaming, the laser machine beam heats the polymer to a given, so some elements begin to foam. Due to the volume change, the material bulges outward, producing clear and textured marks.
The laser color change heats the plastic in precise spots and gets darker (e.g., carbonization) or lighter (e.g., bleaching). The exact outcome depends on the type and composition of the plastic or polymer.

Aside from metals and plastics, the laser marking system is also compatible with other composite materials such as ceramic, paper, and wood using techniques such as laser engraving and laser annealing. Furthermore, the marking system is also compatible with parts with surface coatings.
Choosing the right portable laser engraving machine comes with understanding how the machine works and other needed prerequisites. These might be highly demanding. However, below are a few factors that will help choose the best portable laser engraver.
Price is a huge factor when deciding to get a portable laser engraver. Unlike traditional laser engravers, a portable engraving machine is portable while still exceptionally good for industrial use. A portable engraving machine also boasts of heightened ease of operation due to its features. Therefore, the price of getting one is higher than the conventional laser engravers.
Software compatibility is an important factor when looking to get a portable laser engraver. There are two options available. You can get a portable laser engraver with its software. Therefore, you have to ensure your designs fit into the engraver&#;s software. The second option is to get a portable laser engraving machine that can work with your software. Therefore, when you create a design with your software, it will be compatible with it. A good example of a software-compatible engraver you can get is the portable 20w fiber laser marking machine.
What do you think will improve the ease of operation the portable laser engraving machine is popular for in terms of power source? Battery support, of course! In conjunction with a corded power source, having a portable laser engraver with a battery option also makes it easy to use in any condition.
The laser source is also an important feature to look at when getting a portable laser engraver. Look for a machine using a noiseless laser source that makes the process environmentally friendly.
Although this might not be essential, it is never the less important. It is better to find a portable laser engraver that does not need to connect directly to a computer. Most portable laser engravers we know use USB sticks to connect to the computer. This further ensures ease of operation.
Portable laser engraver also varies in their portability due to the weight factor. This is based on the different features of the machine and the optimization given by the manufacturer. Therefore, when choosing a portable laser engraver, choose one with the right size and weight that can complement the functions. However, note that weight also drives prices. Therefore, portable laser engravers with a smaller size that can be used industrially, such as the portable fiber laser marking machine, have more features and higher prices.
