Search. Logos and illustrated designs and patterns can also be used. Molded plastic parts have become ubiquitous components of industrial equipment, medical devices, aerospace & aviation components, vehicle & marine parts and common household appliances. For laser marking of transparent plastic materials, polymer films with dispersed nanoparticles can be used as an absorber of a laser beam. Exemples d'applications de marquage laser et de gravage laser sur plastique . Factor de selección. This video is unavailable. In collaboration with beverage manufacturers and other related parties, Ricoh will promote circulative recycling by eliminating plastic bottle labels. My first few attempts at laser marking plastic with a 20W fiber laser. Particularly in the labelling of plastics, laser marking has developed into an established method. Laser marking is becoming more and more frequent in industrial applications as they are seen as particularly reliable and provide numerous advantages. In the case of plastics, the process is characterized by a fast marking speed and low cycle times. 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. At Brilliance Laser Inks we can … … 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. These lasers emit in the infrared, but their output can be converted into green or ultraviolet (UV) light, too. transparent, boosted by multiple additives, etc. Les lasers CO 2 sont considérés comme des lasers de classe IV et leur utilisation est recommandée dans un système de classe I. A holeless marking can be achieved on plastics ranging from PET bottles to thin film materials. Since laser welding does not make contact with products, it won't damage them or produce burrs. Laser marking plastic phone case . Nous utilisons les plastiques de qualité inégalé Rowmark! Ensinger therefore offers a selected portfolio of plastic stock shapes which are very suitable for laser marking. Discover some examples of marking on different plastics here: Polymer clarity, spectral transmission, and base physical properties are not affected. For most laser marking applications, solid-state lasers such as Nd:YAG, fibre lasers and CO2 lasers are the ideal beam sources. 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. It uses a neodymium-doped YAG crystal as an active medium. 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. Laser Printing on Plastic. This website uses cookies to improve functionality and performance. Plastics are a widely used material in manufacturing industry. In contrast, the ablation-generated marking … (27), Au nanoparticles (average diameter of 3 nm) dispersed in ethylcellulose was applied to an absorber for laser microfabrication of a transparent plastic. 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. Plastic garbage is a global concern, and Japan has formulated a resource circulation strategy for plastics. For example, POM (acetal) and polyamide PA without modification do not usually display any colour change upon marking with a NdYAG laser. Thus, circulative recycling will be promoted through coordination among these three sectors. Its application can also be of a high quality. 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. Laser marking dark plastic tag . For additional information, please see our. At Ensinger, successful trials have been performed with the Nd:YAG solid-state laser. MARKiNG COLOURS. 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. Ricoh's new technology uses a laser beam to mark plastic bottles and can draw letters as well as patterns on them. Ricoh intends to extend the application of this technology from plastic bottles to other transparent resin products to provide new value. TECAFORM AH LM white is a modified POM-C that is lasermarkable (UV) and complies with requirements of food and pharma industry. Laser marking of plastic, or plastic engraving, is a process during which components are labelled or marked with the aid of a laser. In the event there wasn’t any label, clearly you wouldn’t have to peel one off in order to make your bottle recyclable. 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. Laser marking is extremely robust and also forgery-proof. 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. 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. The strategy sets out a milestone: to attain 100% utilization of used plastic by 2035 by reusing, recycling, or by other means. along with other resins for marking with variety of different lasers like 1064 nm Nd:YAG-Laser, fiber laser and solid state lasers. 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. These formulations achieve line detail at impressive speeds on plastics that have historically been difficult to laser mark. The UV output option is a common choice for marking … Lasers can be used to draw fine patterns directly onto the surface of a plastic bottle, allowing information to be displayed without using ink. So laser marking makes a lot of sense, for plastics as well as other materials. Laser marking is a non-contact optical process in which the plastic has to absorb the laser beam. (Exemple) Marquage de zone étendue sur un LSI L’irradiation laser pour colorer le plastique sans le graver garantit un endommagement minime de la cible. A marking in which it appears that white characters are floating from the surface is possible for transparent or translucent PET plastic. Especially in medical technology and automotive engineering plastics are proving to be enormously efficient and are establishing technological trends. 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. Application Services / Business Process Services. The contact-free method can also be used to mark hard-to-reach and curved surfaces of the part. Laser marking on plastics in the medical and automotive industry Its versatility and its relatively low cost make plastic a universal material. A variety of laser media are used here, and these differ in how the laser is generated. It only effects the surface (about 10 microns deep). By scattering the light we can maximize the whiteness of any print. PPSU medical grade material has improved performance in terms of temperature, impact strength and chemical resistance. Recycling companies will be able to reduce costs as they no longer need to remove any unwanted labels. Countless applications across all industries benefit from this. De plus, il est possible de marquer en une seule fois une zone de 330 × 330 mm max., ce qui contribue à réduire les frais en équipements mécaniques, indispensables pour déplacer la cible … modified pom for laser marking - TECAFORM AH LM white, PEEK 30 glass filled - TECAPEEK GF30 natural, PP biocompatible - TECAPRO MT black/white, Permanent marking, as it is waterproof, wear- and heat-resistant, lightfast and resistant to chemicals, Maximum flexibility in the marking design – also suitable for locations that are hard to access, Simple handling, no pre or post-treatment required.
