"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. For laser marking of transparent plastic materials, polymer films with dispersed nanoparticles can be used as an absorber of a laser beam. The polymer that the plastic parts are made up of dictates the methods used and the energy input needed to laser mark the plastic. Generally, the fiber laser generates a white mark on any plastic base color. Laser marking on plastic Speaking about plastics means referring to derivatives from very different chemical compositions, which influence the performance … Plastic types suitable. for polyamide, polyethylene, ABS and many other plastics. Laser marking allows the efficient and rapid marking of an identifier on a polyethylene surface, even in harsh environments. However, due to the relatively low melting point of polyethylene, laser marking and engraving can lead … Plastics. With a tolerance range of 6 mm, it is perfect to mark flat surfaces either moving or immobile. Looking for a laser marking machine? There are many options for laser engraving and laser etching plastics. Laser beam marking processes are suitable for a wide range of materials, including metals (for instance aluminium, stainless steel, brass, copper, chromium, and titanium), ceramics, and plastics (such as ABS, Plexiglas, PBT, polycarbonate, and polyethylene; plastic materials can become darker in colour with the blackening process or lighter with foamed marking). 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. (27), Au nanoparticles (average diameter of 3 nm) dispersed in ethylcellulose was applied to an absorber for laser microfabrication of a transparent plastic. For plastics Laser Marking, the mechanism is to irradiate the polymer with a high-energy radiation source, e.g., Ytterbium fiber laser. On the other hand, the transmission ratio for polyimide is about 30% with a green laser (532 nm) but more than 90% with a fundamental laser (1064 nm). Laser marked identifiers on polyethylene surface can withstand heavy salt spray testing and intense UV exposure. Laserax has developed extensive experience with polyethylene plastic laser marking, that allows the company to offer efficient marking processes for this very popular plastic. Foaming works on all polymers, but also on some metals. 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). Color laser engraving can essentially be broken down into two subsets, that of color laser engraving on metal and color laser marking on plastic. CO 2 laser cutter are ideally suitable for the cutting and marking of polyethylene foils. Laser marking on plastics in the medical and automotive industry Its versatility and its relatively low cost make plastic a universal material. Plastics We provide an extensive range of systems for etching, engraving and laser marking plastic. The result of the laser marking largely depends on the type of plastic being used, any additives in the plastic (such as dyes) and the type of laser being used to mark it. As well marking plastics, we also have CO2 lasers that operate as plastic engraving machines, as well as cutting plastics up to 1/2" thick. Marking behavior of plastic is highly variable based on different components, and additives. In Ref. In many cases, laser marking uses fewer materials and costs much less than other labeling methods. Carbonizing on the other hand enables strong contrasts on bright surfaces. Thank you for subscribing to our newsletter! Printing on Plastic. Laser marking on polyethylene can be obtained with either a CO2 or a fiber laser source. Linx provides product identification solutions for plastic marking including inks for enhanced adhesion, specifically designed to adhere to a wide variety of plastics and therefore suitable for printing on polyethylene (PE or PET), polypropylene (PP or OPP), HDPE, PVC and Nylon. For PVC, ABS, and polystyrene, both fundamental and green lasers show low transmission ratio and high absorption ratio, which ensures good marking. The radiant energy is absorbed locally by the material and converted to thermal energy which induces reactions in the target polymer substrate. Laser marking of plastic, or plastic engraving, is a process during which components are labelled or marked with the aid of a laser. Whether you need to mark acrylic, polypropylene, polyethylene, polycarbonate, ABS, PVC, Polystyrene, Silicone, Polyamide or another type of plastic, we have suitable machines for identification marks, imagery and far more. The contact-free method can also be used to mark hard-to-reach and curved surfaces of the part. Due to the thermal laser process, the cut edges of the foils will be melted in one working step. Applications. Especially the high precision and flexibility are crucial arguments for laser systems. Color Laser Marking on Plastics As of this writing, color laser markings for plastics is still limited, but recently developed techniques may … If etching or deep engraving is desired, a CO2 laser will be the laser of choice. Lasers can mark plastics using three different processes - Laser Foaming, Carbonising and Staining. If a high contrast marking is required, a pulsed fiber laser is used. 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.
