With a fiber laser, you can mark many different commercially used plastics, such as polycarbonate, pcb, polypropylene, polyethylene, pmma, polystyrol, and many more with a permanent, quick, high-quality finish. Laser marking is a permanent and customizable method of marking plastic parts. Our plastic marking systems come in a variety of sizes so you can laser mark large parts one at a time, or load the table with a jig of parts to engrave hundreds at once. Questa sezione offre informazioni che vanno dai principi della marcatura e lavorazione della plastica ai vantaggi raggruppati in base alla lunghezza d'onda del laser. 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. Laser marking not only proves to be more economical but also offers marks that is free of contact, prevents tampering, and are resistant to abrasion and wear and other environmental factors. To create permanent marks that convey essential information as well as aesthetic qualities, many manufacturers use laser marking. Quando il materiale di base assorbe l'energia del laser, l'effetto termico aumenta la densità molecolare. Generally, the fiber laser generates a white mark on any plastic base color. On a dark base color, a bright marking occurs due to the foaming of the surface under the influence of the laser. KEYENCE ITALIA S.p.A. Codice fiscale e partita IVA 03932910965Copyright (C) 2021 KEYENCE CORPORATION. The most common processes of laser marking on plastic are carbonization, color change, foaming and engraving. The contact-free method can also be used to mark hard-to-reach and curved surfaces of the part. Topics: Based on the nature of the plastic, its functional purpose and its intended use the requirements for its marking are varying. In the case of plastics, the process is characterized by a fast marking speed and low cycle times. The polymer that the plastic parts are made up of dictates the methods used and the energy input needed to laser mark the plastic. Il tasso di assorbimento per la poliimmide invece varia a seconda della lunghezza d'onda: è molto alto per laser UV, mente è basso per un laser fondamentale. Laser marking plastics in a variety of ways. Marking provides a printing-like finishing on designs and other surfaces that cannot be erased. Laser marking plastics offers fast, non-contact processing which helps maintain the integrity of the material. Questa pagina mostra alcune applicazioni e informazioni sulla lavorazione laser. The light is diffusely reflected, and the marking on dark plastic appears bright. In most cases pressing too much when marking can be counterproductive and can decrease the final contrast, so it is better to start with 1 repetition and gradually increase them. "Cos'è esattamente un laser?" In a way, plastics and laser marking … UV Laser Marking Machine : Well-suited for marking heat-sensitive materials, including a number of plastics, from HDPE and silicone to polycarbonate and polyethylene. Da bottiglie in PET a materiali a pellicola sottile, è possibile ottenere una marcatura senza microfori. Laser marking is achieved by the interaction of radiation with the polymer and laser-absorbing additives. We are pleased to support you in the selection of a suitable compound and with customised solutions. Laser Marking Plastic | Accubeam Molded plastic parts have become ubiquitous components of industrial equipment, medical devices, aerospace & aviation components, vehicle & marine parts and common household appliances. A dark marking is caused by carbonization of a light plastic surface. but there is more than meet the eye. The markability is objectively tested according to ISO/IEC TR 29158 (former AIM DPM-2006 guideline). In light of the increasing complexity of plastic components and the requirements for quality assurance, marking of plastics is an essential process for many industries. Laser-markable engineering plastics from AKRO-PLASTIC with special laser-sensitive additives are labeled as LA and are also available with a high percentage of reinforcing materials. La finitura ad alta visibilità simile alla stampa non scompare come l'inchiostro. L'irradiazione dalla luce laser si traduce in un colore bianco molto visibile sulla superficie della plastica. Laser marking of plastic, or plastic engraving, is a process during which components are labelled or marked with the aid of a laser. Check out our 2020 buyer's guide to the top 10 laser marking machines. In questa sezione troverete applicazioni per numerosi settori, oltre a esempi dettagliati che mostrano i vantaggi dei marcatori laser. L'utilizzo di un laser per irradiare la plastica ai fini della colorazione senza incisione garantisce danni minimi al target durante la marcatura. AKRO-PLASTIC works hand-in-hand with customers to develop new and innovative plastics solutions that meet the challenges of the future. Marcatura su involucro di circuito integrato. Explore how we help you with our expertise in practice. Queste bolle sono particolarmente visibili con materiali di base più scuri e portano a una "lieve" colorazione. Le marcature sono bianche e nitide, quindi sono ideali per timbri, etichette e stampe. All Rights Reserved. Looking for a laser marking machine? Lasers are extremely fast, incredibly accurate, can be used for different materials, and produce minimal waste. Quando si effettua la marcatura ad alta potenza, il surriscaldamento può provocare dei microfori. High performance for laser cutting, engraving and marking of sheet and roll materials. It have so wide application nearly in all industry fields, business fields and other daily supplies. L'irradiazione dalla luce laser si traduce in un colore nero sulla superficie della plastica. Includes an overview of the different technologies. For special applications, colorful markings on a dark base color can be achieved. Quando un'area riceve in modo continuo un'energia elevata, le macromolecole dell'elemento attorno al materiale di base vengono carbonizzate e diventano nere. The resulting raised markings are about 20 to 40 μm high and relatively wide. Foaming or melting are surface-altering processes. Non-contact laser marking is ideal for barcodes, UID codes, QR codes, logos, and other identification needs. Gli elementi del "pigmento" nel materiale di base contengono sempre ioni metallici. The result of the laser marking largely depends on the type of plastic being used, any additives in the plastic (such as dyes) and the type of laser … Il grafico sotto mostra il tasso di assorbimento di un laser fondamentale (1064 nm), un laser verde (532 nm) e un laser UV (355 nm) per vari materiali plastici. The marking process produces such little heat, that sensitive products and delicate materials remain largely unharmed. Laser Engraved ABS Plastic. This video is unavailable. Lasers can mark plastics using three different processes - Laser Foaming, Carbonising and Staining. Discover our broad range of engineering plastic compounds. Lasers also offer versatility since they can process a wide variety of different plastics in different ways. Rimuovere la vernice o la stampa sulla superficie del target per far risaltare il contrasto con il colore del materiale di base. Questa sezione illustra le tecniche di marcatura e selezione del laser in base al materiale. Laser sensitive additives are also available as Masterbatch at AF-COLOR and can be combined with different polymers. For laser marking plastics, the laser selectively melts the matrix material, creating gas bubbles which become trapped during cooling. Scoprite tutto ciò che riguarda gli argomenti di base sui laser, come i principi di oscillazione e le caratteristiche in funzione della lunghezza d'onda. Learn more here: http://www.marking-central.com/YTAutoMD. Laser marking for traceability and laser engraving of logos or graphics, on metals end plastics, is spreading for its great effectiveness and saving in the long period.LASIT Laser markers are designed on the specific needs of the client, from the mechanical system to the software.
