Laser beam energy is used to break down or change the structure of individual molecules, such as color pigments. Ricoh's new technology uses a laser beam to mark plastic bottles and can draw letters as well as patterns on them. All rights reserved. It is an, allow different types of processes to implement permanent markings. "If we can't get the contrast needed or get excessive melting, we then go to one of the YAG laser systems.".

Other White character marking is possible on transparent/translucent PET plastics. But if you can achieve the desired mark with a 3 to 60 W diode-pumped unit, then over a five-year period the cost of ownership will be less than for a comparable lamp-pumped unit." The marking equipment provider you choose can make (or break) your project success. Thus, circulative recycling will be promoted through coordination among these three sectors. With a laser marker, you can adjust layouts by simply changing the program. For example, depending on the material and the power of the laser, we will be able to remove more material with the laser, incise more deeply and make deeper and more deep markings. Mixed Pricing Outlook for Commodity Resins, How to Select a Plastics Assembly Process, In-Mold Labeling: Electrostatics Are the Way to Go. spray Lasermarkingis often used in various industries to implement quality, long-lasting, permanent marks. Their various compositions mean different outcomes for any processes applied to them, including laser marking. Environmental issues are another driving force. Schlather points out this kind of system can also be used to mark a larger area without moving the part or tray of parts. Particularly in the labelling of plastics, laser marking has developed into an established method. By using laser radiation to develop a color instead of engraving the plastic, damage from marking the target is minimized. cut. |Privacy Policy. It is an excellent option to take advantage of laser technology to avoid using other methods that generate waste such as stickers, ink, etc. Absorption by the macromolecular structure of plastics is usually in the ultraviolet and far infrared range. For laser marking plastics, the laser selectively melts the matrix material, creating gas bubbles which become trapped during cooling. On the other hand, CO2 lasers may not do very well in marking these two plastics without special additives. Many laser-marking color/additive formulations have been based on surface-treated mica pigments, such as the popular Afflair and Laser Flair lines made by EM Industries. , the irradiation of the laser beam implements a black color on the surface of the plastic, quality marks, this marking process is known as annealing. High resolution allows small letters (about 6 pt) to be used for ingredient information. Lasermarking machines allow different types of processes to implement permanent markings. A laser with a different wavelength could overheat the plastic, causing micro-holes and burns. Although most laser marks are in gradients of black or white, special color concentrates now allow almost any color to be marked on black parts. The steering system sweeps the laser beam using two computer-controlled mirrors, or galvonometers, that move the beam in x and y directions. Download this checklist for the critical questions to ask when shopping for a marking equipment supplier. Using frequency-doubled (532 nm, green) or tripled (355 nm, UV) solid-state lasers extends the range of plastics that are easy to mark. (Photo by Thom Lang. Curiosidad sobre mquinas lser? With this new alternative, labels can be eliminated, and therefore plastic garbage reduced.This technology will benefit consumers, beverage manufacturers, and recycling companies alike.

Focusing first on automotive applications, Ticona began with the introduction of two laser-markable black acetal grades, Celcon LM90 and LM90Z.

colors, descriptions. Carbonization creates very dark marks on very bright surfaces. Use a laser system with low output. UV marking lasers, fiber lasers and solid-state lasers in the infrared wavelength range are ideally suited as beam sources for laser marking plastics. Decorating thermoplastics with laser marking has taken longer to gain acceptance than was expected a decade ago.

Lasers mark plastic components not only permanently and flexibly, but also very environmentally and material friendly. laser. LASIT Sistemi e Tecnologie Elettrottiche S.p.A. | Via Solferino 4, 80058 Torre Annunziata (NA). It is an excellent option to take advantage of laser technology to avoid using other methods that generate waste such as stickers, ink, etc. Lasering POM, in particular, is often a challenge, which is why TECAFORM AH LM white has been modified with a laser additive. The formulator or masterbatch supplier needs to know about the resin, end-use application, and type of graphics required. The low heat conductivity in plastics means low energy losses during marking. Recent developments include mergers of the two leading laser-marking equipment suppliers, Rofin-Baasel, Inc. (formerly A-B Lasers), which offers both CO2 and solid-state Nd:YAG systems, and GSI Lumonics (the product of an earlier merger of General Scanner Inc. and Lumonics). The strategy sets out a milestone: to attain 100% utilization of used plastic by 2035 by reusing, recycling, or by other means. take maximal advantage of our products. Lasers are much more flexible in coping with such challenges, tolerating even minor surface soiling, and able to begin marking immediately without having to first create templates, which is required, for example, by screen and pad printing processes. For example, depending on the material and the power of the laser, we will be able to remove more material with the laser, incise more deeply and make deeper and more deep markings. Among the current limitations of the technology are restricted ability to obtain a color-matched laser mark and the cost of laser-optimized plastics, which typically sell at a 10-15% premium and sometimes more. A CO2 laser etches the plastic surface, removing material by evaporation.

The Infrared FiberFly laser provides good contrast, and the MOPA version is recommended when increases contrast is desired. We produce unique chemical ink substrates for color laser ID cards. The FlyUV laser induces a photochemical reaction in the material, producing high, continuous, and permanent contrast, leaving the surface smooth to the touch. Says color-business manager Stuart Swain, "There are tremendous opportunities for different colors to be marked white, green, or yellow on a black background.". As a result, laser marking provides a printing-like finish that cannot be erased. Leading suppliers of custom color and additive masterbatches for laser marking are Clariant and PolyOne. Color change, for example from dark to light or vice versa, using a laser ensures minimal damage to the component during marking.

The pulse of the FlyPeak laser always stays below 10 ns throughout the range (at 20 kHz = 3.5 ns). Dark gray markings can then be made on light materials. "The advantage of such a system is that it can be easily retrofitted into existing production lines to maximize throughput. Soldadura, limpieza, grabado, corte y mucho ms! Laser Engraving Products 2008 Heves Laser Inks, Ltd. In fact, polycarbonate, polyamide, polyester, PE, PET, ABS, to name a few, are all plastics. Encoder feedback is provided to the computer which makes appropriate adjustments to track the moving target in real time. See the photos. The Heves inks help concentrate the laser in the ", RTP is now offering several neat and reinforced laser-markable compounds of PP, nylons (6, 66, 12, 11, and 612), ABS, LLDPE, acetal, polysulfone, PBT, syndiotactic PS, TPU, TPO, PPS, acrylic, PC/acrylic, PC/ABS, and LCP. On what surfaces can we mark with lasers? Plastics can therefore be marked much faster than metals. Above all, it has become more important in the context of quality assurance and traceability. Limpieza Lser This means the surface stays cooler compared to traditional nanosecond lasers, including fiber lasers. Laser wavelength plays an important role in the marking of plastics, depending on the application. Consequently, the composition of the element itself changes chemically, resulting in color development due to the increased intensity of the pigment. The laser marking of plastics basically involves three separate processes: changes in color, alterations to surfaces and the ablation of layers. These new options appear to be gaining considerable interest in high-end SAN cosmetic packaging and polyolefin shampoo and conditioner bottles and closures, as well as toys. optimize the material, the type of CO2 laser and the power or energy. cutting results with printed acrylic. The key to laser marking plastics is achieving sufficient absorption of the laser beam into the material. Even degrees of shading are now possible. See the, laser Multi-layer or coated plastics can be laser-marked by ablating a thin top layer. The pigment elements in a base material typically contain metallic ions. It will depend on the laser equipment we get and the power of our laser. signs (e.g. This industry faces several problems, one SummaryPottery is made from clay, sand, or other similar materials. Examples of successful commercial applications include ABS keyboards for business machines; HDPE, PP, PET, and PVC rigid containers and closures; nylon and PBT automotive and non-automotive electrical connectors; and underhood components such as fuse boxes and gas caps. Most of Clariant's laser-marking masterbatches are customized. Discoloration is caused by the break-up of chemical compounds. Laser Marking Fundamentals and How to Use a Laser Marking Machine. Starting from the results of the first tests, they can identify the parameters that work best for the specific job. Heves is optimal for etching anodized aluminum or coated Laser marking can be one of the most successful ways to mark or engrave plastics -- over labels, printing, and other alternatives -- when you are using the right type of laser marking machine for your application. Commodity resins such as PP filled with mica produce a frosted pale-white mark using a CO2 laser. Surfaces remain largely unaffected and smooth. Consumers will no longer need to peel off labels and they will spend less time classifying their recycling, thereby increasing their likelihood to recycle. Read: How to Solve Common Ultrasonic Welding Problems. CO2 lasers with a short wavelength (9.3 m) enable clear marking with minimal damage. Irradiate a plastic target with a laser to develop a color in the target itself. When an area receives continuous high energy, the macromolecules of the element around the base material are charred and turn black. Blasius expects that a broader range of colors will be achieved in the next few years. Marcado Lser With a laser marking machine , the irradiation of the laser beam implements a black color on the surface of the plastic, quality marks, this marking process is known as annealing. Get advice on your ideal laser equipment, before getting a new laser machine. The laser cut provides flame polished (Photo: PolyOne). Information on production history and specifications are particularly crucial for parts that have the highest liability in case they fail, such as electrical/electronic switch bodies. signs made with our products: photos showing finished products in Today's laser-marking pigment and additive systems can provide contrasting colors and degrees of shading. Using Windows-based "Help" functions, laser-marker suppliers have embedded service and calibration techniques along with troubleshooting software. Plastic materials have vastly different chemical compositions. For example, precision scales can be applied to plastic products used in medical technology. The polymer that the plastic parts are made of dictates the methods used and also the energy input needed to laser the plastic. Detailed can increase production efficiency and efficiency. industry, to avoid the waste of valuable materials and for accurate For a good acrylic cut you need to Peel the paint or printing on the target surface to bring out the contrast with the color of the base material. These more varied color effects are one of the concurrent trends that are bringing renewed interest in decorating plastics with lasers, according to marketing manager Patrick Schlather of Rofin-Baasel, Inc., a leading supplier of plastics laser-marking equipment. You can use A complete turnkey CO2 system sells in the range of $25,000 to $35,000, whereas a lamp-pumped or diode-pumped turnkey Nd:YAG system typically runs $60,000 to $75,000. Poltica de Privacidad y Trminos Legales. our products - Engraving on plastic or painted Laser marking of hard plastics such as Polycarbonate or ABScan increase production efficiency and efficiency. Plastic garbage is a global concern, and Japan has formulated a resource circulation strategy for plastics. Lamp systems require water cooling, while diode types use water or air cooling. They are uniquely formulated and made to order. In carbonization, carbon-containing plastics burn or carbonize on the surface.

The laser is used to create long-lasting, fine, and high-contrast color changes on a multitude of everyday objects made of plastic. But FOBA's Bone projects that diode-pumped system prices will drop in the next few months and that they may eventually replace lamp-pumped units altogether. : references, serial numbers, expiration dates, logos, among other options. This can be done with low This is because the laser removes or changes the surface of the plastic material, or modifies its color, creating a contrast. ", Software that allows marking of plastics with on-the-fly beam steering is also offered by several laser equipment suppliers. The laser dose alters selected molecules and thus brings about a change in color. This removes coatings or special layers in laser marking film. We can meet needs based on manufacturer requirements and the type of product involved. Podrs ejercer, de Acceso, Rectificacin, Limitacin o Suprimir tus datos en info@lasercomercial.com. Laser marking is a non-contact optical process in which the plastic has to absorb the laser beam. As the material does not burn or carbonize, it is referred to as "cold marking" with high surface qualities. different materials. Logos and illustrated designs and patterns can also be used. but also the underlying material. Solid-state Nd:YAG lasers heat the plastic to cause a thermochemical reaction such as foaming and also produce more of a color change. In metals, most of the beam is reflected, while in plastics, transmission, diffuse reflection, and absorption are more important. Not all high-performance plastics are intrinsically capable of being laser marked. Laser marking on hard plastics: ABS and others. The plastics are frequently given bar codes, articles or batch numbers for unique identification. CO2 lasers are ideal acrylic cutting, in signage, Ticona's newest development is Celcon UV140LG, which is said to be the first low-gloss laser-markable acetal copolymer.

Estaremos encantados de contarte ms informacin. Other They're great replacements for stamps, labels and printers. Current color effects Clariant can achieve are primarily gradients from white to gray to black on any color substrate. While there are different processes that lasers can perform on plastic, some are more popular than others. According to Ticona's Miller, most automotive applications involve black substrates with marks in off-white to white. With selective ablation, the laser removes a surface layer from the material. The laser marking does not affect the properties of the plastic bottle. Therefore, UV lasers are typically the best systems to choose for resin marking applications.

2022 Gardner Business Media, Inc. Privacy Policy Industrial ceramics are more heat resistant and have a If we configure the machine with the appropriate parameters, we can also implement other types of markings. Buenos Aires, Argentina To achieve high legibility and marking quality, it is recommended to mix laser-sensitive additives into some industrial plastics. Says Ticona's Miller, "Laser-markable plastics, in conjunction with creative part design and fabrication technology such as two-component molding, has potential for eliminating these secondary operations. Yet, information is required to be displayed on the bottle, so other means would need to be created in order to display the necessary information on the bottle.Ink must not be directly printed onto plastic bottles, as in order to maintain recyclability, the guidelines from the Council for PET Bottle Recycling prohibit direct printing of materials other than PET on plastic bottles.

Lasers can be used to draw fine patterns directly onto the surface of a plastic bottle, allowing information to be displayed without using ink. Most laser software has the capability for mark serialization, multiple types of barcode, and text of any typeincluding company logos. Some examples of laser-engraved By scattering the light we can maximize the whiteness of any print. - Technical manual - Spanish - Videos. listing - See examples of pieces made with The initial parameters they use are normally the ones listed below: In most cases, forcing a marking can be counterproductive and decrease the final contrast. [Log On], Understanding Melting in Single-Screw Extruders, Tracing the History of Polymeric Materials: Part 20. The result of the laser marking depends, to a significant extent, on the type of plastic, additives such as dyes and the type of laser. Foaming or melting are surface-altering processes. Nonetheless, laser technology has been winning converts at the expense of ink marking technologies such as pad printing and inkjet printing in certain markets. The best results were obtained at a wavelength of 1064nm this is also the one that is most frequently used. grade ceramic items like earthenware. On very dark substrates, Clariant can provide a blue, red, or green mark. How Do You Measure Your Energy Footprint? PolyOne has formulated FastMark additives for both neat and glass- or mineral-filled grades of polyolefins, polycarbonate, PC/ABS, and SAN. Schlather from Rofin-Baasel sums up the choice of YAG laser types: "If scheduled maintenance every 600 to 800 hr is acceptable to you, the lamp-pumped systems yield the highest throughput for the least amount of investment. Apart from ABS plastic, with the fiber laser we can mark other surfaces such as: For other industrial applications, is good to know that we can find laser marking equipment prepared to be integrated into production linesand chain productivity processes. Because of the ability to control pulse timing, this laser performs exceptionally well, even for some difficult applications. The time it takes to make pottery or porcelain largely depends on the materials they are made from. Use Industrial ceramics rather than artisan quality. He says, "We have greater knowledge than 10 years ago as to how to use pigments and additives. Laser marking is extremely robust and also forgery-proof. The most popular lasers for marking plastic are the well-known UV laser, the FlyPeak green wave laser from LASIT, and the traditional green light laser with a fiber optic source. Plastics that mark well with CO2 lasers include PVC, ABS, and most polyesters. Here, the use of a UV laser is recommended. High-powered laser beams can overheat targets and create pinholes. If we configure the machine with the appropriate parameters, we can also implement other types of markings. Buttons in vehicle interiors are an example of markings achieved by layer ablation. Laser markers capable of producing a high peak power are optimal (such as a hybrid 1064 nm laser or UV 355nm laser). numbers, bar codes, data matrix codes or logos. better quality surface. (Example) Welding of transparent plastic and colored plastic. This is because the laser removes or changes the surface of the plastic material, or modifies its color, creating a contrast. Rofin-Baasel's Schlather advises processors considering purchase of a solid-state laser to know what throughput is required and all the aesthetic requirements of the marking application. When a base material is irradiated with a laser, gas bubbles are generated inside the material due to the thermal effect of the radiation. The process is typically used for light-colored plastics. Says Barbero, "Today's software allows marking of more than 400 characters per second, compared with 40 type-size, single-stroke characters/sec 10 years ago.". PolyOne also offers concentrates that can provide virtually any color of markingusually on black parts. Bill Blasius, director of technology at Clariant Corp.'s Masterbatches Div., concedes that laser marking has also been limited in its color choices and color brilliance. PPSU medical grade material has improved performance in terms of temperature, impact strength and chemical resistance. In addition, almost no consumables are needed, we save costs and time and obtain very satisfactory results. Destinatarios: tus datos se encuentran alojados en la plataforma Hub Spot inc. ubicada en EEUU y acogida al Privacy Shield.

Foaming is therefore usually used for black and dark colors. For a three-shift marking operation, Schlather says ink and chemicals can cost $20,000 to $40,000 per year while printing plates can cost $100,000 per year or more, depending on complexity, durability, and marking changes. (Photo: PolyOne), Laser-marked TPU ear tags for swine and cattle ensures that data on breeding, feeding, and medical history accompanies each animal to market. It also features UV resistance. Typically, a bottle is made of PET (polyethylene terephthalate) resin and a label is made from a different type of resin.In the event there wasn't any label, clearly you wouldn't have to peel one off in order to make your bottle recyclable. GDPR methods such as rotary engraving or sandblasting can be replaced with a ", Adds Schlather from Rofin-Baasel, "Current systems use straightforward graphics-creation software that can be easily programmed to mark unique data on each and every part on the fly. Use the heat of laser radiation to weld and join plastic parts. wood, plastic or metal - laser etching - laser coloring on steel - target marking. RGPD Laser marking uses no inks or solvents, nor does it require the energy-intensive drying steps typical of ink-marking technologies. Copyright (C) 2022 KEYENCE CORPORATION. engraving directions. Particular, RGPD us about Color Laser Engraving on Plastic. In adittion, the higher the output power the faster the Laser markers are able to mark PET bottles, thin films and most products in-between without leaving pin holes. type plates), or in the promotional materials industry.

Product traceability has become a major driving force behind this technology, notes Rick Stevenson, sales manager at Control Microsystems, another laser supplier. To make the proper choice, each application must be considered on its own. On other occasions we can change the color of our material and make the desired design. According to Schlather, laser marking meets these requirements with spot sizes and position repeatability in the range of 0.001 in.performance that is difficult to match with pad or inkjet printers. The result is a contrasting mark but little or no true color change. Its adjustable pulse duration ensures high contrast without burns. methods such as rotary engraving or sandblasting can be replaced with a Since laser welding does not make contact with products, it won't damage them or produce burrs. 2020 Manufacturing Regulations Making a Mark on Traceability, 5 Dos and 5 Don'ts for Selecting the Marking Technology Your Product Needs, Customer Service that Speaks Directly to Your Bottom Line, 6 Ways Laser Marking Will Save You Time and Money. Lasers are also being used more for icons and images (such as at upper left), in addition to just alphanumeric characters. Compared to ink jet, laser marking does not have the problem of ink adhesion, dark substrate contrast, or finish complexity. Research at BASF's laser-marking laboratory in Germany has shown that addition of glass fibers reduces the markability of plastics only slightly, but some fillers, flame retardants, and even regrind can greatly reduce markability. Beverage manufacturers will be able to reduce the cost of printing labels and make their products more environmentally friendly. Since lasers with different wavelengths are available, the wavelength can be optimized for the respective material. At Ensinger, successful trials have been performed with the Nd:YAG solid-state laser. TECAFORM AH LM white is a modified POM-C that is lasermarkable (UV) and complies with requirements of food and pharma industry. Countless applications across all industries benefit from this. engraving on plastic, metal, ceramics or other materials. Still others include TPE ear tags for swine and cattle, appliance parts like HDPE on/off knobs on washer/dryer units, and PVC plumbing parts such as elbows and fittings.
