JPT Fiber Laser Engraver Laser Marking Machine 50W, 110×110mm

Product Information

This fiber laser cutter also comes with an 80mm rotary axis included for marking cylindrical objects. There are two techniques for color filling engravings: using masking tape and wiping with toilet paper. Secondly, the peak power of fiber lasers is very high. Even if the optical power of the machine is 50-100 watts, the peak power can reach up to 5000-10,000 watts. It is because fiber lasers can also work in the pulsed operation mode that offers pulses of very intense energy. Thus, these lasers can engrave and cut hard materials, such as metals, without any hassle. These wavelengths are considerably lower than those of CO2 lasers, which typically operate at around 10,600nm. The shorter wavelengths of fiber lasers are well-suited for absorption by reflective metal surfaces, whereas CO2 lasers are primarily reflected. It is required when parts cannot be positioned accurately, when different part models are used, or when surfaces are highly curved. Information to Gather Before Speaking with an Expert

As the light propagates through the fiber cable core, it interacts with a cladding layer made from refractive material. This cladding helps focus the light in a single direction. The light then enters the laser cavity, a small portion of the fiber cable where the laser’s wavelength is determined. The specific wavelength produced depends on the dopant material used within the cavity. Color laser marking is possible on most plastics including ABS, PVC, Polyethylene, and glass-filled plastics. Best Lasers for Color EngravingYou can use denatured alcohol to wash off the chars. Using alcohol is easier than sanding the chars off. Step 5: Paint

Designed, tested, manufactured and Made in Britain to the very highest standards, the Meta range come in a variety of configurations including MOPA Fiber, Ultraviolet and CO2 laser sources. This method doesn’t require any preparation before the engraving, so you can use this method on any engraving. The fiber laser engraver I’d recommend to most users is the Datouboss 20W Laser Marking Machine. This relatively affordable, super-powerful laser offers accurate marking across a wide range of materials, with different sizes available to suit your workspace.When you buy a laser, you need to know if it is a certified class-1 laser product. Several organizations regulate laser products all over the world, but the most trustworthy certifications are ANSI Z136.1, FDA CFR 1040-10, and IEC 60825. Ytterbium-doped fiber lasers produce a wavelength of 1064 nm, which makes them ideal for the material processing of metals. These are the fiber lasers that Laserax uses for metal marking and cleaning applications. Autofocus technology uses vision to detect variations in part positioning and adjust the laser focus accordingly. This ensures that the engraving process is always optimal. Without a certification, fiber laser engravers are considered class-4 lasers. This means that the laser beam and its reflections can cause eye injuries, skin burns, and fires. The dust and fumes generated during laser engraving can also be dangerous for workers. Getting a certified laser is essential to protect workers against laser hazards. Certified Lasers

Mildly sanding the surface can remove any leftover painted spots. It can deliver a cleaner surface. Laser Engraving in Color Using Color Powder If you frequently change the type of part you are marking, you need more advanced software capabilities and an easy-to-use interface. The software should be connected to a vision system to detect parts and display them visually on the user interface. You should be able to easily enter new traceability information, such as by touching the screen where you want to add the identifier. Custom Engravings In laser marking, the laser heats the spot until it goes through oxidation and changes color, causing a chemical reaction on the material’s surface. It’s also really easy to get started with this machine, even if you’re a beginner – the laser comes fullycalibratedand it’s simple to install.You can use a brush or spray paint to paint the material without worrying that the paint stains areas outside the design. You can also use different colors in different areas. Make sure that you have not left any spot unpainted. Step 6: Peel Off the Mask It’s a super sturdy machine with an all-metal structure with an anodized coating that makes it very robust and durable.

Another plus is the silent motherboard which ensures smooth movement and that there’s no noise during engraving. It has a robust control system and a unique design to ensure quality and accurate marking for your business endeavors. Things We Like: Built with Siemens PLC electronics, military-grade aluminium the Meta range is built to the highest quality and comes with lifetime remote support. The laser device and beam quality alone are impressive. It uses a JPT LP series laser with much better flexibility (and frequency range of 1-600KHz). Thus, it can be better controlled and gives a more precise and perfect engraving, especially compared to Q-switched fiber lasers. Things We Like:Engraving in color has artistic and practical applications. There are several methods of color engraving besides several techniques for creating monochromatic contrasts. Use toilet paper to wipe the surface in gentle and smooth strokes. The goal is to clean the surface without disturbing the engraving. The color laser engraving procedure on metals involves annealing them. Yet, plastics don’t have the same chemical reactions. So, lasers can’t produce similar results on plastic (at the moment).
