With a fiber laser, you can mark a variety of different commercially used plastics, such as polycarbonate, ABS, polyamide, and many more with a permanent, quick, high-quality finish. Laserax has developed extensive experience with polyethylene plastic laser marking, that allows the company to offer efficient marking processes for this very popular plastic. Thank you for subscribing to our newsletter. In Ref. You want to bring your expensive outsourcing of marking inhouse. Polyethylene does not readily absorb the energy of a 1.06 micron fiber laser. for polyamide, polyethylene, ABS and many other plastics. Laser marking … Cutting of polyethylene can be performed with a CO 2 laser to produce a clean non-discolored cut with a slight raised edge near the point of ablation. Laser marked identifiers on polyethylene surface can withstand heavy salt spray testing and intense UV exposure. 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. Polyethylene terephthalate (PET) is a thermoplastic polyester material. Amongst other things, ... chemically resistant, durable and virtually unbreakable, and perfect for marking and cutting with CO 2 laser. The laser marking machine for plastic works on a low power level and longer pulses. Printing on Plastic. They’re certified for the IP67 class protection, and offer a laser power of up to a 100 W. The LXM Series provides flexibility and durability without compromising on precision or speed. Laser marking of plastic, or plastic engraving, is a process during which components are labelled or marked with the aid of a laser. White paper Plastic Laser Marking. 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). In both cases, a proper fume extraction system is required to move the fumes from the work area. The LXM laser series comprises CO2 laser with optical power ranging between 20 and 70 W. It is the ideal laser for marking rubber, polyethylene, ABS and other organic material such as ceramic. Nylon: produces contrast by foaming. The LXQ series offers the most efficient and reliable industrial laser marking machines on the market. CO 2 laser cutter are ideally suitable for the cutting and marking of polyethylene foils. PET/PETG is used for machine protection devices, glazing, shop and trade show furnishings and in the general furniture sector. (27), Au nanoparticles (average diameter of 3 nm) dispersed in ethylcellulose was applied to an absorber for laser microfabrication of a transparent plastic. The radiant energy is absorbed locally by the material and converted to thermal energy which induces reactions in the target polymer substrate. In this video, an LXM laser system is used to brand a rubber sample. Generally, the fiber laser generates a white mark on any plastic base color. Thanks to the low set-up times and flexibility that a marking laser offers, you can mark small batch sizes easily and economically. Marking behavior of plastic is highly variable based on different components, and additives. 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. If a high contrast marking is required, a pulsed fiber laser is used. Especially in medical technology and automotive engineering plastics are proving to be enormously efficient and are establishing technological trends. In many cases, laser marking uses fewer materials and costs much less than other labeling methods. Especially the high precision and flexibility are crucial arguments for laser systems. Trotec Laser Engraving & Laser Cutting Machines. The CO2 laser is more often use for etching or engraving the plastic. Applications. Connect the laser to your computer through an ethernet or USB connection. Laser marking operates via fast, noncontact techniques to produce clear codes and images that resist temperature extremes, abrasion, and time. For PVC, ABS, and polystyrene, both fundamental and green lasers show low transmission ratio and high absorption ratio, which ensures good marking. However, due to the relatively low melting point of polyethylene, laser marking and engraving can lead … Key button and rocker switches: Technical controls in day-night design The day/night design marking allows for a perfect visibility of symbols and signs on backlit operational controls in any lighting conditions.
