In a way, plastics and laser marking … Troverete sicuramente un laser adatto per le vostre esigenze. If you are looking to laser engrave ABS plastic, we have the materials and resources that you need. Le molecole si condensano e il colore cambia diventando più scuro. Questa è una lettura imprescindibile se prima volete controllare la gamma dei laser KEYENCE! La finitura ad alta visibilità simile alla stampa non scompare come l'inchiostro. AKRO-PLASTIC’s history stretches back over 30 years. Explore how we help you with our expertise in practice. Marcatura su involucro di circuito integrato. The resulting raised markings are about 20 to 40 μm high and relatively wide. AKRO-PLASTIC works hand-in-hand with customers to develop new and innovative plastics solutions that meet the challenges of the future. The CO 2 laser is more often used for etching or engraving on the plastic. The radiant energy is absorbed locally by the material and converted to thermal energy which induces reactions in the target polymer substrate. Laser marking plastics offers fast, non-contact processing which helps maintain the integrity of the material. Fiber laser marking machine in Plastic filed Plastic is one of the most common material in our life. We are pleased to support you in the selection of a suitable compound and with customised solutions. Foaming or melting are surface-altering processes. The successful marking with the settings I used is at the end of the video. Non-contact laser marking is ideal for barcodes, UID codes, QR codes, logos, and other identification needs. Lasers can mark plastics using three different processes - Laser Foaming, Carbonising and Staining. Discover our broad range of engineering plastic compounds. Learn directly from our AKRO Experts.

Questi riferimenti tecnici forniscono risposte alla portata di tutti, sia a chi è interessato a domande elementari come queste, sia a chi desidera informazioni più approfondite ad esempio sulle strutture di un oscillatore. High performance for laser cutting, engraving and marking of sheet and roll materials. 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. Sulla superficie la marcatura produce una finitura indelebile simile alla stampa. Laser marking of plastic, or plastic engraving, is a process during which components are labelled or marked with the aid of a laser. A dark marking is caused by carbonization of a light plastic surface. Presenta esempi di marcatura e i marcatori laser migliori per diversi materiali, come ABS, resina epossidica e PET. Laser marking on plastics may seem like a simple task. 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. Although it is more difficult to laser mark than polypropylene or PV., the additives present in polyethylene plastic allows the application of a laser mark with a high contrast identifier, when proper laser parameters and wavelength are used. The laser choice will depend on the application requirements. Quando un'area riceve in modo continuo un'energia elevata, le macromolecole dell'elemento attorno al materiale di base vengono carbonizzate e diventano nere. Di conseguenza, la composizione dell'elemento stesso subisce una trasformazione chimica, determinando un viraggio dovuto alla maggiore intensità del pigmento. To create permanent marks that convey essential information as well as aesthetic qualities, many manufacturers use laser marking. By selecting a suitable combination of plastic compound and laser, it is possible to mark without pre-treatment or post-processing steps. "Su quali principi si basa?" 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. Rimuovere la vernice o la stampa sulla superficie del target per far risaltare il contrasto con il colore del materiale di base. Laser marking on plastic can be obtained with either a CO 2 or a fiber laser source. Learn more here: http://www.marking-central.com/YTAutoMD. Polyethylene is an important plastic used in packaging and bottling industries. AKRO-PLASTIC uses a fiber laser from REA Elektronik GmbH for testing the markability of plastics (picture reference). 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. Quando il materiale di base assorbe l'energia del laser, l'effetto termico aumenta la densità molecolare. La radiazione laser cambia la struttura cristallina degli ioni e il livello di idratazione nei cristalli. In the case of plastics, the process is characterized by a fast marking speed and low cycle times. 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.
