Online Magazine, Entire overview Color molecules can be selectively bleached out or their color changed. Laser markings on plastic surfaces are always smudge and abrasion resistant. Regardless of whether you are producing small or large-volume components or handling small or large lot sizes – TRUMPF's laser marking systems ensure the best possible ergonomics and safety at all times. Non-contact laser marking is very fast as well as abrasion, heat and acid resistant, and many different plastics can be marked or engraved with a laser. Cold and non-contact laser marking means that the component surface remains virtually unaffected. “Laser Marking” of plastics is a noncontact digital process whereby indelible information is applied onto a target substrate surface with minimal material penetration. Applications, Entire overview The laser achieves even the most intricate markings which are high-contrast, clean, and without any smudges. "On-the-fly" laser marking is one of the most highly specialized applications performed on molded and extruded products such as wire/cable, tubes, and pipes. The flexible laser tool applies high-contrast and permanently legible, high-resolution product markings even in difficult to access areas. Moreover, not all plastics are the same. The laser marking of plastics basically involves three separate processes: changes in color, alterations to surfaces and the ablation of layers.>. The marking process produces such … For laser marking plastics, the laser selectively melts the matrix material, creating gas bubbles which become trapped during cooling. Contrast is created by the color of the base material or base coating. You can set your browser as you wish and generally prevent the setting of cookies. Dark gray markings can then be made on light materials. Linear marking speeds of text and machine vision codes can achieve 500 ft/min and faster, where inkless laser marking now replaces rotary gravure and pad printing… 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. The main objective of marking systems is the long-term legibility of markings, but ink, for example, has inherent limitations. The process is typically used for light-colored plastics. Plastics can therefore be marked much faster than metals. Using frequency-doubled (532 nm, green) or tripled (355 nm, UV) solid-state lasers extends the range of plastics that are easy to mark. Industries, Entire overview Smart Factory, Process cutting: Shears, slitting shears and nibblers, Process fastening: Seam lockers and power fasteners, Process bevelling: Deburrers and bevellers, Entire overview Our high-performance engraving materials are offered in over 300 color combinations. For example, precision scales can be applied to plastic products used in medical technology. Multi-layer or coated plastics can be laser-marked by ablating a thin top layer. Press releases, Entire overview The laser choice will depend on the application requirements. The laser is used to create long-lasting, fine, and high-contrast color changes on a multitude of everyday objects made of plastic. Plus custom fabrication is available. Laser marking on plastics in the medical and automotive industry Its versatility and its relatively low cost make plastic a universal material. Media service, Entire overview Laser marking is the most flexible way of marking plastics and yields legible, sharp and indelible images. Download it here. Molded plastic parts have become ubiquitous components of industrial equipment, medical devices, aerospace & aviation components, vehicle & marine parts and common household appliances. As the material does not burn or carbonize, it is referred to as "cold marking" with high surface qualities. Contact People, Entire overview Different material types behave differently while progressing with laser marking 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. The product surface is colored photochemically. Foaming is therefore usually used for black and dark colors. We offer premium engraving, ADA, cast and extruded acrylic and architectural sign substrates for laser … 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. Machines & systems, Entire overview Plastic This section introduces a variety of information, from plastic marking/processing principles to laser features according to wavelength. Laser marking on plastic can be obtained with either a CO 2 or a fiber laser source. In metals, most of the beam is reflected, while in plastics, transmission, diffuse reflection, and absorption are more important. In daylight, the symbols are white and at night they are backlit. With the TruMark 6030 marking laser, you can make the most of the advantages offered by the next generation of marking lasers by TRUMPF. Copyright © 2020 MECCO. To create permanent marks that convey essential information as well as aesthetic qualities, many manufacturers use laser marking. Discoloration is caused by the break-up of chemical compounds. These lasers often achieve better results than standard systems with wavelengths of 1,064 or 1,030 nm. The laser radiation of the Endurance semiconductor (diode) lasers melts the upper layer of the processed material, which allows to engrave or cut samples of acrylic, plastic, and rubber up to 10 mm thick. Polyethylene is an important plastic used in packaging and bottling industries. With a wavelength of only 355 nm, this UV … Further details can be found in the privacy policy, Lasers mark plastic components not only permanently and flexibly, but also very environmentally and material friendly. The resulting raised markings are about 20 to 40 μm high and relatively wide. Laser Printing on Plastic Our laser marking additives can be used in polyolefins like PP, HDPE, PS, ABS, PC, TPU, PET, PBT, Nylon, PVC and TPE etc. The low heat conductivity in plastics means low energy losses during marking. 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 … TRUMPF uses cookies to provide a variety of services, to continually improve these services and to display advertisements according to the interests of our visitors. Surfaces remain largely unaffected and smooth. 7 MB, Entire overview VCSEL solutions & photodiodes, Entire overview Advantages of TRUMPF machines, Entire overview Fiscal year figures 2019/20, Laser welding systems and the arc welding cell, Entire overview Especially in medical technology and automotive engineering … Laser marking on plastic Speaking about plastics means referring to derivatives from very different chemical compositions, which influence the performance of the processes applied to them, including … Challenges for Plastic Laser Marking Machine Manufacturers.
