Nowadays, in the industrial world, almost all industries need to adopt laser technology, especially by adding laser marking machines into their production line. Generally, there are many specific kinds of laser marking machines, in this passage, I will introduce the four most popular types of laser marking machines to you.
Here is the content list:
l Annealing laser marking machine
l Carbon Migration laser marking machine
l Foaming laser marking machine
l Coloration laser marking machine
The first I am about to mention is the annealing laser marking machine. Annealing mark refers to the oxidation process of applying heat to the surface material without applying a lot of corrosion. This type of laser marking usually produces a pure black mark with a smooth surface, but depending on the temperature of the marking surface, the color can also vary between shades of yellow, red, and green. This process is usually slower because annealing only relies on heat to bring carbon from the metal to the surface and form marks. After the metal is heated, it must be gradually cooled. Common metals that can be marked in the laser annealing process include titanium, steel, stainless steel, and iron. Besides, this process can be used in a variety of industries. However, it is most commonly used in applications such as internal tracking and branding in the medical industry.
The third one carbon migration is another type of laser marking in which a metal or metal alloy is heated to chemically bond the metal to its carbon molecules. This bonding brings carbon properties to the surface of your material. When this happens, a dark laser mark is usually produced, and it may even be black. Compared with annealing, this type of marking process is faster because it can provide a lot of heat to a smaller area in a shorter time. By the way, only metals containing carbon can be marked with this type of laser. Common metals suitable for carbon migration include steel, stainless steel, carbide, and titanium. Industries that use carbon migration for beneficial applications include aerospace, jewelry carving, metalworking.
When the plastic color is dark and the desired final result is a lighter color, usually white, gold, or various tans, then the foam laser marking can be used. The color change occurs by producing melting burns on surfaces of materials. When the surface melts, it creates an atmosphere of bubbling bubbles. These bubbles will change the light refraction characteristics of the material, so that when the product surface needs to emit light effects, text, symbols, etc., making foaming become an ideal process. Foam is not used on metal, instead, it is used only on plastic, since making metals to bubbling is much harder. This feature makes it a valuable asset in the plastics industry and industries that regularly use plastics in their businesses.
Depending on the expected result, the process of adding color to plastic or metal varies. A colored laser marking is created by heating specific parts of the surface of the material. Modifying the colors of the surfaces by controlling the pulse frequency, width, etc., of the laser will result in changes in color and shading, so it is very important to know the desired result in advance. When the plastic is colored, it can be colored through a foaming process. When manipulating the polymer in plastic, it produces a certain wavelength of color, usually infrared to ultraviolet light. Metal coloration occurs through an oxidation process, which can be applied to previously treated and untreated surfaces. This provides users with more freedom in coloring effects, and can even be used for decorative applications. As a result, lasers used for colored markings can generally operate over a wide range of frequencies, speeds, power levels, etc.
