In Ref. Lasering POM, in particular, is often a challenge, which is why TECAFORM AH LM white has been modified with a laser additive. Our specialty compounds have the ability to deliver an excellent mark for both transparent and non-transparent plastics. This technology will benefit consumers, beverage manufacturers, and recycling companies alike. With a Fiber laser, you can mark many different commercially used plastics, such as polycarbonate, ABS and polyamide with a permanent, quick, high-quality finish. In the case of plastics, the process is characterized by a fast marking speed and low cycle times. Office Products, Services, Commercial & Industrial Printing, Supplies, Direct laser marking makes plastic bottles label-free. The most popular lasers for plastic applications are the famous UV laser, the green wave FlyPeak laser by LASIT and the traditional green light Laser, with fiber optic source. My first few attempts at laser marking plastic with a 20W fiber laser. In transparent laser plastic welding (TLPW) a higher wavelength laser is used, which interacts differently with the plastic than the typical 808nm or 980nm infrared lasers used in through-transmission welding. Pores may appear as a result of overheating when marking with high power. Its application can also be of a high quality. Logos and illustrated designs and patterns can also be used. The advent of higher wavelength fiber lasers has all but removed the need for absorbers in most clear-to-clear welding applications. “AF-Color LA” masterbatches incorporate laser-sensitive additives from AF … What’s more, Laser marking can be integrated at any point of the assembly line as well as offline (or standalone), resulting in flexibility in marking and logistics. MARKiNG COLOURS. Further advantages of plastic laser marking (versus conventional marking technologies) are: During the laser marking through laser beam exposure, the plastics undergo optical surface changes. This website uses cookies to improve functionality and performance. Their ability to be produced and shaped at low cost, in addition to their unique properties, explain why they are present everywhere in our daily life. Laser marking on plastics in the medical and automotive industry Its versatility and its relatively low cost make plastic a universal material. Non-contact digital laser m… High resolution allows small letters (about 6 pt) to be used for ingredient information. Accordingly, efforts are being made to promote bottle-to-bottle recycling. Loading... Close. 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. A marking in which it appears that white characters are floating from the surface is possible for transparent or translucent PET plastic. Les lasers CO 2 sont considérés comme des lasers de classe IV et leur utilisation est recommandée dans un système de classe I. From the production of technical plastics to the finished product, Technifor's solutions mark all types of plastic, both natural and colored. Laser marking is the most flexible way of marking plastics and yields legible, sharp and indelible images. These formulations achieve line detail at impressive speeds on plastics that have historically been difficult to laser mark. In addition, you can mark areas of up to 330 × 330 mm, all at once, and reduce costs of mechanical equipment, thanks to the elimination of the need to transport the object, as with conventional methods. Lasers can mark products with various geometries in a fully computer-controlled process with high reproducibility and reliability. Laser marking is becoming more and more frequent in industrial applications as they are seen as particularly reliable and provide numerous advantages. Lasers can be used to draw fine patterns directly onto the surface of a plastic bottle, allowing information to be displayed without using ink. A distinction is drawn between gas, dye and solid-state lasers. transparent, boosted by multiple additives, etc. Plastic Processing Plastic marking The optimal laser marker for this task is a hybrid laser marker that has a high peak power within the fundemental wavelength. So laser marking makes a lot of sense, for plastics as well as other materials. Il existe une panoplie de couleur de plastique gravable au laser. Skip navigation Sign in. Laser marking is increasingly replacing conventional printing methods. Panasonic offers: Pretests and transmission measurement Planning a defect-free installation of single components. Nd:YAG stands for neodymium-doped yttrium aluminium garnet laser. Lorsque la cible est un objet transparent, le marqueur laser idéal pour toute opération de pelage et de découpage est le marqueur laser CO 2. Thus, circulative recycling will be promoted through coordination among these three sectors. Compared to lasers, other direct marking techniques like dot peen don’t always play well with plastic shapes and surfaces. A promising alternative is to use a laser to alter the surface of a plastic bottle. Countless applications across all industries benefit from this. Laser plastic welding 3 Injection molding 8 Quality management 9 Laser marking 10 Service 4 Storage 5 Handling/ feeding Suitability tests of common materi-als. Nous utilisons les plastiques de qualité inégalé Rowmark! This video is unavailable. At Ensinger, successful trials have been performed with the Nd:YAG solid-state laser. (Example) Welding of transparent plastic and colored plastic. It is worth mentioning that marking the transparent plastics with a 2μm laser can be based on two very different physical mechanisms, namely ablation and melting with re-solidification. The contact-free method can also be used to mark hard-to-reach and curved surfaces of the part. 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. Above all, it has become more important in the context of quality assurance and traceability. These lasers emit in the infrared, but their output can be converted into green or ultraviolet (UV) light, too. To recycle a plastic bottle, you need to remove the label from the bottle because they are made from different materials. Since laser welding does not make contact with products, it won't damage them or produce burrs. Search. Molded plastic parts have become ubiquitous components of industrial equipment, medical devices, aerospace & aviation components, vehicle & marine parts and common household appliances. 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. En d’autres termes, vous devrez protéger le point de marquage afin d’empêcher que des personnes ne regardent le laser ou placent les mains devant l’élément optique de sortie. Laser marking is a non-contact optical process in which the plastic has to absorb the laser beam. At Brilliance Laser Inks we can … (1) Optical technology The laser marking does not affect the properties of the plastic bottle. The printed letters are easy to see. Bouchon en plastique marqué au laser . The UV output option is a common choice for marking … The successful marking with the settings I used is at the end of the video. Ricoh's new technology uses a laser beam to mark plastic bottles and can draw letters as well as patterns on them. Irradiation d’une cible en plastique par laser afin de développer une couleur dans le matériau même de la cible. Ricoh Group companies are striving tirelessly to develop solutions that reduce any adverse impacts on the environment at the same time as increasing their own recycling capabilities. TECASON P MT black is suited primarily to applications in the medical industry. Laser Printing on Plastic. laser marking machine for transparent plastic. During the lasering of plastic the result is influenced not only by the type of laser but also by the wavelength used. Laser marking dark plastic tag . The polymer that the plastic parts are made of dictates the methods used and also the energy input needed to laser the plastic. 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).
