Futonics fiber lasers are ideal for welding a variety of clear and colored thermoplastic materials. This is helpful for figuring out where the laser will cut before you run your job on your material. Our fiber lasers can ablate, etch and engrave coated metals. Marking speed is a function of many variables, including polymer type, substrate color, laser additive type and loading level, cable size (weight), laser type and power, software, number of alphanumeric characters, text height, length of text string, space between characters, bar code/data matrix, logos/graphics, single-stroke or true-type filled fonts, fill direction, and continuous or repeating text. Laser marking solutions provider MECCO acquires FARO Photonics. Laser engraving can also be used to convey information. ... Our more powerful fiber lasers come in 20-50 watts, and can easily remove the powder coat and mark the underlying surface. Using a fiber laser on wood is essentially like starting a campfire. Benefits rapidly offset the incremental material additive cost. Breakthrough FDA-approved laser additives incorporated into polymers yield superior marking contrast, line edge detail, and speed. When adjusting settings, a good rule is to adjust either the power or the speed. Another solution might be to coat a white or transparent part with a clear, nanoparticle-bearing polymer film that selectively absorbs the appropriate wavelength. Power settings that are too high can melt and distort many materials. Designed for affordable ytterbium fiber lasers, in-line inkless laser marking now replaces traditional rotary gravure and pad printing. Australian Journal of Mechanical Engineering: Vol. Monday – Friday 9am to 5pm CST (Lunch from 12:00-1:00pm CST) Thulium fiber laser welding of polymers. Designed for affordable ytterbium fiber lasers, in-line inkless laser marking now replaces traditional rotary gravure and pad printing. Laser Engraving Settings. Another side benefit to a fiber laser is their ability to bleach pigment from polymer. In the field of polymer optical fibers, femtosecond laser FIGURE 1. The advantages of 2 µm thulium fiber laser welding of polymer-metal and polymer-polymer combinations have been recently reported. workpiece height: 4.9 - 12.0 inch : Laser power: 20 - 120 watts LUMOSCRIBE LTD is an R&D company located in Cyprus that specializes in the development of custom-made optical fibre sensors, and monolithic fibre lasers, whilst also working on niche optical sensing solutions using Artificial Intelligence. 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. The selection of which laser type to integrate is determined by the output characteristics of the laser interacting with the optimized polymer material. Pump power in percent, as explained above. As you can see in the following graph, metals absorb the fiber laserโ€™s wavelength (1064 nm) more efficiently than the CO2 laserโ€™s (10.6 µm). 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). Choosing a laser engraving machine for yourself. IPG Photonics offers reliable fiber laser. Homogeneous distribution/dispersion of laser additives throughout each part is critical to achieve optimal marking performance. [3]. Clear, semi-transparent, and opaque colored polymers, including nylons, polyethylene terephthalate (PET), polycarbonates, polyolefins, polyvinyl chloride (PVC), styrenics, and thermoplastic elastomers (TPUs) and thermoplastic polyurethanes (TPEs), are uniquely formulated using non-heavy metal, FDA/European Food Safety Authority (EFSA)-approved additives to achieve high-contrast marking quality (FIGURE 1). Current activity in Lithuania is demonstrating new laser technologies and applications. Then run the file and watch where the red dot goes. Marking speeds for polyolefin synthetic wine corks and undercap promotions on linerless beverage closures are capable of 2000 pieces/min for alphanumeric text and graphics (FIGURE 4). We demonstrated efficient and photostable laser action in graded index polymer fiber lasers doped with organic dyes such as Rhodamines, Perylenes and Pyrromethenes. CO2 are gas lasers that are perfect for working with non-metallic surfaces. For extrusion, injection molding, and thermoforming operations, precolor compounded materials vs. color concentrate yields better uniformity. Vastly different formulation chemistries and laser optics/setup parameters are used depending upon the desired marking contrast and functionality. For both graphs, the particular combination of parameter inputs controls the output properties of the laser beam, namely the pulse energy, the peak power (the highest instantaneous peak of the pulse energy, joules/pulse duration), and the average power (average power in watts = pulse energy in joules × pulse repetition rate in hertz). So many people use fiber laser engraving machine marking on rubber engraving. 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. Laser welding of polymers is a set of method used to join polymeric components through the use of a laser.Laser radiation can be generated by CO 2 lasers Nd:YAG lasers, Diode lasers and Fiber lasers. With this merger, the two laser micromachining companies are convinced that respective customers will benefit from the pooling of operations. Focused laser spot size for any given focal length lens and laser wavelength is a function of laser beam divergence, which is controlled by laser configuration, mode selecting aperture size, and upcollimator (beam expander) magnification. Laser Power โ€“ The percentage of available power you are utilizing. used in processing of a variety. Linear marking speeds of text and machine vision codes can achieve 500 ft/min and faster, where inkless laser marking now replaces rotary gravure and pad printing.FIGURE 4. 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. Optical taper of polymer optical fiber used in laser communication system Optical taper of polymer optical fiber used in laser communication system Guo, Li-li 2006-02-23 00:00:00 The key technique of optical wireless communication is Acquisition, Pointing and Tracking (APT). The laser choice will depend on the application requirements. 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. 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. However, when the beam travels into wood, its absorption canโ€™t be controlled. Experts utilize additives, fillers, pigments, and dyes to enhance the absorption of laser energy for localized color changes. Pulse repetition rate and peak power density are critical parameters in forming the mark and achieving the optimal contrast and speed. “Laser Marking” of plastics is a noncontact digital process whereby indelible information is applied onto a target substrate surface with minimal material penetration. 95-108. 2. On-the-fly laser marking of high-density polyethylene (HDPE) undercap promotions on linerless beverage closures enables up to 2000 closures/min. I have been in contact with Trotec's support staff and cannot get one single answer to anything it seems. Direct ink printing puts an image on the surface of the plastic which can be removed by abrasion or solvents, but Laser marking can provide an indelible high-contrast mark in the material itself, with no direct contact with the plastic other than through the incident Laser beam. A laser with superior beam quality can be focused to a small spot size, which leads to high energy density. New Managing Director Sebastian Blösch previously served as the laser marking company's Finance Director and Deputy Managing Director. Power density is a function of focused laser spot size. On the other hand, fiber lasers are best suited for engraving on metals. SCOTT R. SABREEN (ssabreen@sabreen.com) is the founder and president of The Sabreen Group, Plano, TX, www.sabreen.com. © 2021 Endeavor Business Media, LLC. Power settings that are too high can melt and distort many materials. Laser transmission welding is sometimes used to weld polymers, but is not useful for fibers because of the laser wavelength and fiber sizes involved. 17, Design, Manufacturing and Materials, pp. Non-contact digital laser marking replaces expensive adhesive labels and ink-chemical printing processes.
