However, for general purposes, consider the following nylon polymer example involving a 50W fiber laser, 254mm flat field lens, 100 alphanumeric characters, 2mm height, a repeating text string length of 14.68in., and marking time of 0.232s. Fiber Coupled Laser Welding Products; Benefits of Fiber Coupled Welding; 8600 Fiber Compact Welding System; Focus Heads for Laser Welding; Financing. solutions for each unique application. It has been traditionally difficult to achieve white contrast using long-pulse-width lasers. New Managing Director Sebastian Blösch previously served as the laser marking company's Finance Director and Deputy Managing Director. This type of mark uses the energy of the laser beam to alter the molecular structure of the piece, then change the color of the substrate without damaging the surface. High precision welding that results in accurate joint formation In addition to contributing to The Firearm Blog, he hosts and blogs for The Firearms Podcast, a podcast and blog about gun stuff by gun people.Scott is a 20-year veteran of the USAF and been a member of his base, state and the All Guard marksmanship teams. on technology, operation, process, and graphic design. The advancements achieved in formulating laser chemical additives for use with near-infrared (NIR) lasers (1060–1080nm wavelength) are their compatibility with ytterbium fiber, vanadate, and predecessor Nd:YAG lasers. In the field of polymer optical fibers, femtosecond laser but you could just as easily engrave with a V-bit. CO2 are gas lasers that are perfect for working with non-metallic surfaces. Fiber Lasers vs CO 2. Information is typically in the forms of alphanumeric text, symbols, graphics, logos, schematics, barcodes, machine vision codes, etc. In contrast to fiber-delivered lasers, the entire path of the beam is within a fiber-optic cable all the way to the beam delivery optics. Color adjustments are made using pigments and dyes to achieve the final colormatch appearance. The laser I use has the option to turn on a laser pointer that projects a red dot where the cutting/engraving laser will fire. The laser light is By optimizing the laser setup, there is minimal surface carbonization residue. Other additives can contain aluminum particles, mixed metal oxides, and proprietary compounds. All fiber lasers are not created equal. half the available power of the laser. Optimized material-science chemistry for plastics laser marking requires expertise in polymers, colorants, pigments, and dyes relative to solubility, particle sizes, threshold concentration limits, color match, and regulatory certifications (GRAS, FDA Direct/Indirect Food Contact). If you’d like to learn more about ablative laser cutting, check out this article on Micron-Scale Manufacturing.. 2 Reasons NOT to Use a Fiber Laser to Engrave Wood. Laser type: CO₂, Flexx or Fiber laser : Work area: 24.0 x 12.0 up to 40.0 x 24.0 inch : Max. Monday – Friday 9am to 5pm CST (Lunch from 12:00-1:00pm CST) 3. from pulsed lasers used in precision. Ready-made fixture plates and components save laser marking companies from the cost and time it takes to design and build their own fixtures in-house. Compared to ink printing processes (pad/screen printing and inkjet), laser additives are cost-saving and can demonstrate 20% and faster marking speeds vs. non-optimized materials. On-the-fly laser marking of high-density polyethylene (HDPE) undercap promotions on linerless beverage closures enables up to 2000 closures/min. The fiber laser marker series offers reduced integration time and cost, and facilitates collaboration between system integrators and laser experts. On-the-fly laser marking systems help save money. uring the last decade, polymer optical fibers (P OF) have . IPG Photonics, a leading developer and manufacturer of high-performance fiber lasers, offers both fixed-pulse YLP Series (sometimes referred to as "Q-switch") and variable short-pulse YLPN (MOPA) lasers. You can find out more about welding polymers using our lasers in the article “Welding of transparent and opaque polymers with single-mode Tm-doped fiber lasers” erfahren. Q-switched fiber lasers, typically with 100–120ns pulse width, are employed for some marking applications, but their repetition rate is limited to around 80kHz because of the inherent constraint of Q-switching technology. The same laser can, however, put a legible, khaki-colored mark on Delrin thatโ€™s been pigmented with light-absorbing carbon black. MECCO has had a well-established relationship with FARO Photonics, leveraging the company’s products in MECCO’s laser marking and processing solutions. used in processing of a variety. Pulse duration influences the degree of heat and carbonization into the material. © 2021 Endeavor Business Media, LLC. M. Gailey, "Plastics additives allow inkless marking," Photonics Spectra (Sept. 2013). fiber sensors, polymer optical fiber, polymer . "Smart additives" enhance plastics laser marking, How carbon dioxide lasers deliver consistent processing quality, Versatile laser marking for identification and traceability. laser machining, marking plastics and metal using a fiber laser (plotter or Galvosystem) can involve different processes. A laser with superior beam quality can be focused to a small spot size, which leads to high energy density. 95-108.
