Lasers also offer versatility since they can process a wide variety of different plastics in different ways. 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. For plastics Laser Marking, the mechanism is to irradiate the polymer with a high-energy radiation source, e.g., Ytterbium fiber laser. It requires fairly low power lasers. La radiazione laser cambia la struttura cristallina degli ioni e il livello di idratazione nei cristalli. La marcatura priva di danni è il metodo migliore per marcare target in cui l'energia del laser potrebbe danneggiare la superficie del prodotto o il suo interno. 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. Polyethylene is an important plastic used in packaging and bottling industries.

Non essendo più necessario spostare i target come avveniva con i metodi tradizionali, i costi delle attrezzature meccaniche si riducono. The polymer that the plastic parts are made up of dictates the methods used and the energy input needed to laser mark the plastic. Di conseguenza, la composizione dell'elemento stesso subisce una trasformazione chimica, determinando un viraggio dovuto alla maggiore intensità del pigmento. Queste bolle sono particolarmente visibili con materiali di base più scuri e portano a una "lieve" colorazione. On a dark base color, a bright marking occurs due to the foaming of the surface under the influence of the laser. "Cos'è esattamente un laser?" Irradiation from the laser light results in a black / highly visible white color on the surface of the plastic. Free of charge and without obligation. In questa sezione troverete applicazioni per numerosi settori, oltre a esempi dettagliati che mostrano i vantaggi dei marcatori laser.

Presenta esempi di marcatura e i marcatori laser migliori per diversi materiali, come ABS, resina epossidica e PET. In the case of plastics, the process is characterized by a fast marking speed and low cycle times. Laser marking of plastics is achieved in a few seconds but guarantees indelible engraving over time. 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. 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. Includes an overview of the different technologies. Thanks to the low set-up times and flexibility that a marking laser offers, you can mark small batch sizes easily and economically. Laser marking of plastics has many advantages of traditional marking methods like ink, dyes and paints. Laser marking on plastic can be obtained with either a CO 2 or a fiber laser source. 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. The contact-free method can also be used to mark hard-to-reach and curved surfaces of the part. 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. Processing and assembly instructions and certificates, as required in the construction industry, can be easily applied to the plastics via laser marking.​ Additionally, laser marked plastics can include logos and or decorative designs for branding and individualization, for example on household appliances and sporting goods.​ In addition to the plastic, the decisive factors for selecting the marking method are the geometry of the molded part and the conditions of use. To create permanent marks that convey essential information as well as aesthetic qualities, many manufacturers use laser marking. In the automotive and E/E industries, plastic parts are often individually marked to enable the traceability of production processes. This video is unavailable. Search. For special applications, colorful markings on a dark base color can be achieved. Marcatura su involucro di circuito integrato. The marking process produces such little heat, that sensitive products and delicate materials remain largely unharmed. The radiant energy is absorbed locally by the material and converted to thermal energy which induces reactions in the target polymer substrate. Arrange an online appointment here. Le bolle gassificate e vaporizzate si trovano nello strato superficiale del materiale di base e creano un rigonfiamento biancastro. Hygienic laser engraving and marking of plastics for medical technology with the help of UV laser markers. The markability is objectively tested according to ISO/IEC TR 29158 (former AIM DPM-2006 guideline). Laser marking on plastics may seem like a simple task. Quando il materiale di base assorbe l'energia del laser, l'effetto termico aumenta la densità molecolare. Looking for a laser marking machine? "Su quali principi si basa?" but there is more than meet the eye. Quando un'area riceve in modo continuo un'energia elevata, le macromolecole dell'elemento attorno al materiale di base vengono carbonizzate e diventano nere. 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. Le marcature sono bianche e nitide, quindi sono ideali per timbri, etichette e stampe. Quando il materiale di base viene irradiato con un laser, l'effetto termico della radiazione all'interno del materiale genera delle bolle di gas. Polyethylene laser marking. Rimuovere la vernice o la stampa sulla superficie del target per far risaltare il contrasto con il colore del materiale di base. Laser Engraved ABS Plastic. Skip navigation Sign in.
