You can then opt on a case-by-case basis whether to allow cookies, generally accept them or reject them. Here, the use of a UV laser is recommended. Discoloration is caused by the break-up of chemical compounds. Contrast is created by the color of the base material or base coating. Smart Factory, Process cutting: Shears, slitting shears and nibblers, Process fastening: Seam lockers and power fasteners, Process bevelling: Deburrers and bevellers, Entire overview Laser marking of plastic, or plastic engraving, is a process during which components are labelled or marked with the aid of a laser. Lasers are much more flexible in coping with such challenges, tolerating even minor surface soiling, and able to begin marking immediately without having to first create templates, which is required, for example, by screen and pad printing processes. To find the best way to laser mark plastics and other materials for manufacturers, the MECCO team uses an evidence-based process to define the requirements, assess technical feasibility, and design a custom solution. The polymer that the plastic parts are made up of dictates the methods used and the energy input needed to laser mark … The key to laser marking plastics is achieving sufficient absorption of the laser beam into the material. Buttons in vehicle interiors are an example of markings achieved by layer ablation. Challenges for Plastic Laser Marking Machine Manufacturers. Based on your configuration, United States might be more appropriate. Laser marking can be one of the most successful ways to mark or engrave plastics -- over labels, printing, and other alternatives -- when you are using the right type of laser marking machine for your application. Laser inscriptions on plastics neither fade nor rub off so remain perfectly legible even after years. Any explicit consent from you to process your personal data can be revoked at any time by unchecking the following checkbox. The marking process produces such … Software, Entire overview The contact-free method can also be used to mark hard-to-reach and curved surfaces of the part. Since lasers with different wavelengths are available, the wavelength can be optimized for the respective material. The optimal laser markers and marking examples are provided for each category, including ABS, epoxies, and PET marking… 020 6675 9800. High-quality, reproducible and fully solvent-free: Joining plastics using lasers has many advantages and numerous applications. Do you want to keep or change the selection? Color molecules can be selectively bleached out or their color changed. In daylight, the symbols are white and at night they are backlit. With a wavelength of only 355 nm, this UV … Lasers also offer versatility since they can process a wide variety of different plastics in … Premium Engraving, ADA and Architectural Sign Substrates B.F. Plastics, Inc. carries a wide variety of plastic and metal engraving materials, corporate award and trophy supplies in a variety of thicknesses, colors and finishes. Applications, Entire overview To create permanent marks that convey essential information as well as aesthetic qualities, many manufacturers use laser marking. Surfaces remain largely unaffected and smooth. The marking equipment provider you choose can make (or break) your project success. SMARTmark® UV Laser Marker is the Answer for Plastics and More [News], 6 Reasons Why Manufacturing Traceability is Essential Now, Top Advice for Turning Industrial Data into Actionable Results, Laser Engraving Plastics: How to Navigate the Challenges. The product surface is colored photochemically. Marking speeds for polyolefin synthetic wine corks and undercap promotions on linerless beverage closures are capable of 2000 pieces/min for alphanumeric text and graphics (FIGURE 4). With a Fiber laser, you can mark many different commercially used plastics, such as polycarbonate, ABS and polyamide with … At present, the best Rolex Replica are Swiss movements, assembled in Hong Kong, white steel color is 316L steel or 904L steel, gold part is 18K gold or rose gold, work fine, accurate and stable walking, … These lasers often achieve better results than standard systems with wavelengths of 1,064 or 1,030 nm. Laser marking is a permanent and customizable method of marking plastic parts. Laser marking is a non-contact optical process in which the plastic has to absorb the laser beam. The laser marking of plastics basically involves three separate processes: changes in color, alterations to surfaces and the ablation of layers.>. One of the key features that makes plastics so difficult to mark successfully is the wide variety of compounds available, including polycarbonate, polyethylene, and silicone; furthermore, common fillers, extenders, and additives as well as colors. Laser marking is the most flexible way of marking plastics and yields legible, sharp and indelible images. How do I Ensure High-Quality Laser Marks?
