laser marking transparent plastic

 In Uncategorized

Panasonic offers: Pretests and transmission measurement Planning a defect-free installation of single components. For plastics marking, the source is most typically a solid-state (vanadate) laser, since these provide the short pulse duration that usually delivers the most pronounced color or contrast change in the plastic without any thermal damage to the material. Above all, it has become more important in the context of quality assurance and traceability. For the latter, it is possible that rise in temperature in the later process may cause these marks to disappear if the temperature reaches beyond the melting point of the chosen plastic material. Compared to lasers, other direct marking techniques like dot peen don’t always play well with plastic shapes and surfaces. A variety of laser media are used here, and these differ in how the laser is generated. (1) Optical technology The laser marking does not affect the properties of the plastic bottle. Voici un échantillon de la grande variété de couleur de plastique disponible! Ampacet laser marking products are compatible with most polymers and can be used with all laser types to provide high levels of contrast and shading. 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. Especially in medical technology and automotive engineering plastics are proving to be enormously efficient and are establishing technological trends. Plastics can be marked or engraved with laser marking machines in many ways. The laser marking does not affect the properties of the plastic bottle. along with other resins for marking with variety of different lasers like 1064 nm Nd:YAG-Laser, fiber laser and solid state lasers. 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. 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. Nous utilisons seulement les plastiques Rowmark dus à leur grande qualité et leur choix incomparable de couleurs et textures. This behaviour is also used in the laser welding of plastics, during which one welding partner absorbs the laser beam and the other welding partner is transparent for the laser beam. 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. Factor de selección. 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 dark plastic tag . To create permanent marks that convey essential information as well as aesthetic qualities, many manufacturers use laser marking. laser marking machine for transparent plastic. In the event there wasn’t any label, clearly you wouldn’t have to peel one off in order to make your bottle recyclable. Nous utilisons les plastiques de qualité inégalé Rowmark! 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. Discover some examples of marking on different plastics here: This website uses cookies to improve functionality and performance. Skip navigation Sign in. laser marking machine for transparent plastic. The contact-free method can also be used to mark hard-to-reach and curved surfaces of the part. Irradiation d’une cible en plastique par laser afin de développer une couleur dans le matériau même de la cible. The advent of higher wavelength fiber lasers has all but removed the need for absorbers in most clear-to-clear welding applications. Thanks to the low set-up times and flexibility that a marking laser offers, you can mark small batch sizes easily and economically. Lasers can mark products with various geometries in a fully computer-controlled process with high reproducibility and reliability. Laser marking of plastic, or plastic engraving, is a process during which components are labelled or marked with the aid of a laser. Our laser marking additives can be used in polyolefins like PP, HDPE, PS, ABS, PC, TPU, PET, PBT, Nylon, PVC and TPE etc. transparent, boosted by multiple additives, etc. The best results were obtained at a wavelength of 1064nm – this is also the one that is most frequently used. Laser marking is increasingly replacing conventional printing methods. 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. Exemples d'applications de marquage laser et de gravage laser sur plastique . Bouchon en plastique marqué au laser . In contrast, the ablation-generated marking … It uses a neodymium-doped YAG crystal as an active medium. Ricoh's new technology uses a laser beam to mark plastic bottles and can draw letters as well as patterns on them. Laser marking is a non-contact optical process in which the plastic has to absorb the laser beam. Les lasers CO 2 sont considérés comme des lasers de classe IV et leur utilisation est recommandée dans un système de classe I. Many plastics and thermoplastics can be laser marked. Not all high-performance plastics are intrinsically capable of being laser marked. 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. Particularly in the labelling of plastics, laser marking has developed into an established method. My first few attempts at laser marking plastic with a 20W fiber laser. Our laser marking additives can be used in polyolefins like PP, HDPE, PS, ABS, PC, TPU, PET, PBT, Nylon, PVC and TPE etc. These formulations achieve line detail at impressive speeds on plastics that have historically been difficult to laser mark. 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. The strategy sets out a milestone: to attain 100% utilization of used plastic by 2035 by reusing, recycling, or by other means. Laser Printing on Plastic. Lasering POM, in particular, is often a challenge, which is why TECAFORM AH LM white has been modified with a laser additive. German compounder AF-Color (Niederzissen; www.af-color.com) has introduced two colour masterbatches that are combined with additives for optimised laser-marking and improved laser-transparency in laser-welding applications.AF-Color is a subsidiary of Akro-Plastic (Niederzissen; www.akro-plastic.com). Should a plastic’s properties dictate that it cannot be laser marked, it can usually be modified with a suitable additive or master-batch for plastic … PPSU medical grade material has improved performance in terms of temperature, impact strength and chemical resistance. In the case of plastics, the process is characterized by a fast marking speed and low cycle times. This behaviour is also used in the laser welding of plastics, during which one welding partner absorbs the laser beam and the other welding partner is transparent for the laser beam. This video is unavailable. Thus, circulative recycling will be promoted through coordination among these three sectors. With this new alternative, labels can be eliminated, and therefore plastic garbage reduced. For laser marking of transparent plastic materials, polymer films with dispersed nanoparticles can be used as an absorber of a laser beam. 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. It only effects the surface (about 10 microns deep). TECAFORM AH LM white is a modified POM-C that is lasermarkable (UV) and complies with requirements of food and pharma industry. The use of a laser to irradiate the plastic in order to color it without engraving it, ensures minimal damage to the object during marking.
