Laser Marking and Engraving Metal

Laser Marking and Engraving Metal

There are various ways to mark and engrave metal. Depending on the application, these methods include CO2 lasers, Tabletop lasers, and Fibre lasers. You should also know that oxidation marking is also a popular technique. For more information about these methods, see our article on oxidation marking. You can also use a combination of techniques. Detailed instructions are provided in the following paragraphs. If you are looking for Laser Marking and Engraving Metal visit this website

Fibre lasers

Fiber lasers can mark and engrave a variety of materials. These machines are particularly efficient at engraving metals such as stainless steel, iron, aluminium, and titanium. Compared to other laser cutting methods, they leave the engraved material intact. The advantage of using a fiber laser over other technologies is its small area of heat affected zone and its ease of automation. Fibre lasers are the perfect tool for marking metal without using tools.

CO2 lasers

There are several advantages of using CO2 lasers for marking and engraving metal. Unlike other lasers, CO2 lasers don’t affect the metal itself. Instead, they produce a permanent engraving. Since the metal doesn’t change its texture or color, the mark left behind will be permanent and impossible to erase. They also help to reduce environmental pollution, since they use no inks or glues that can harm the environment. Plus, CO2 lasers have a high useful life, lasting up to 100,000 hours, and require practically no maintenance.

Tabletop lasers

There are many types of tabletop lasers for marking and engraving metal, including DPSS, CO2 and fiber. DPSS is a high-power laser module with an average power of four watts. CO2 lasers are not recommended for metal marking or engraving because they are not compatible with EzCad software, which includes barcoding and other useful features. Fiber lasers are a more appropriate choice thetechboy.

Oxidation marking

Laser oxidation marking on metal is one of the fastest methods for making permanent, clean marks on various types of metal. The technique works by heating the metal with oxygen assist gas, creating a layer of oxidized material. The oxidation process is done to control the depth of the chemical change on the metal surface. Unlike traditional methods, laser oxidation marking is not abrasive and is not likely to harm the metal or the surrounding tissue. In addition, laser marking is also compatible with automation, vision systems, and robotic elements, further driving the results.

Deep engraving

Deep engraving metal is an important process in the manufacturing process, and it requires a high-quality laser machine. Most laser engravers come with quality-optimized laser parameters, which are designed to achieve maximum engraving depth of 200 um. Deep engraving is usually more difficult than other processes, and the laser machine must have more power to complete the task efficiently. With a high-quality laser, however, you can easily achieve a 220 mm depth.
