Laser marking machines come in a wide variety of types; for instance, UV laser markers, fiber laser markers, and CO2 laser markers are all common types of laser equipment frequently encountered across numerous processing industries. Since different materials and products require the application of specific laser marking machines, today we would like to introduce you to another novel and relatively advanced type: the Green Laser Marking Machine.
The green laser marking machine is a common variant within the laser marking family. Utilizing a side-pumping mechanism-distinct from end-pumped semiconductor laser markers-it offers distinct advantages: it emits a green laser with a wavelength of 532nm; when focused, it produces a smaller spot diameter with more concentrated energy; furthermore, it boasts high electro-optical conversion efficiency and excellent beam quality.
So, what types of products are suitable for marking with a green laser marking machine?
- Plastic Materials: When used to mark plastic drinking cups, the green laser marking machine ensures a result that is non-toxic, eco-friendly, and free of contaminants. It is also capable of marking computer peripherals (such as mice and keyboards), plastic packaging bottles for cosmetics and skincare products, as well as high-volume consumer goods found in supermarkets-such as shampoos, body washes, and laundry detergents. The green laser marking machine enables the creation of high-contrast, clearly legible markings on plastic materials.
- Silicon Materials: The green laser marking machine is capable of performing "soft marking" on silicon-based materials.
- Gold and Silver Jewelry: The green laser marking machine can also achieve high-quality marking on highly reflective materials such as gold and silver. For various gold and silver jewelry items-including rings, bangles, bracelets, and necklaces-it can be used to mark logos and intricate patterns, and can even be utilized to engrave customized text.
- Glass Materials: Glass is highly susceptible to breakage during the marking process; consequently, marking on glass requires extreme caution. The optimal engraving method varies depending on the specific type of glass, particularly its lead content. As the lead content increases, the glass's hardness and high-temperature viscosity decrease, making it more fragile and prone to shattering. Therefore, the green laser marking machine undoubtedly stands out as a superior choice for such applications.
- Transparent Materials (such as Crystal): Crystal has historically been the material of choice for crafting a wide variety of artistic items. It can be used to engrave personalized gifts and keepsakes-such as 2D/3D portraits, names, handprints, footprints, and trophies-as well as for the mass production of 2D/3D models (depicting animals, plants, architecture, vehicles, ships, and aircraft) and 3D scene displays.
- Electronics Industry Products: Including electrical appliances, telecommunications equipment, electronic components, electrical products, integrated circuits, and PCBs.
- Metal and Hardware Products: Surface processing or thin-film coating processing for items such as automotive parts, decorative crafts, metal pendants, eyewear, timepieces, nameplates, and display panels.
- Ceramics: Green laser marking machines can be used to engrave patterns and designs-as well as manufacturers' logos and identification QR codes-onto various ceramic items, including tableware, decorative crafts, and mugs.
