laser marking plastics
With a Fiber laser, you can mark many different commercially used plastics, such as polycarbonate, ABS and polyamide with … The laser is used to create long-lasting, fine, and high-contrast color changes on a multitude of everyday objects made of plastic. Robust plastics laser-marking operations require engineering expertise in areas ranging from the selection of polymeric resins and their chemical formulations through systems integration-a total solutions methodology approach that includes material-science chemistry, primary molding operations, laser … For laser marking plastics, the laser selectively melts the matrix material, creating gas bubbles which become trapped during cooling. 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. The key to laser marking plastics is achieving sufficient absorption of the laser beam into the material. Shop engraving plastic at Hansen Supply. My first few attempts at laser marking plastic with a 20W fiber laser. Media service, Entire overview These lasers often achieve better results than standard systems with wavelengths of 1,064 or 1,030 nm. Please note that up until revocation, the legal validity of consent-based processing remains unaffected. Foaming or melting are surface-altering processes. The polymer that the plastic parts are made up of dictates the methods used and the energy input needed to laser mark … Machines & systems, Entire overview How do I Ensure High-Quality Laser Marks? 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 laser marking of plastics basically involves three separate processes: changes in color, alterations to surfaces and the ablation of layers.>. Polyethylene laser marking. In metals, most of the beam is reflected, while in plastics, transmission, diffuse reflection, and absorption are more important. The varying properties and additives in plastics often require individualized marking solutions. To create permanent marks that convey essential information as well as aesthetic qualities, many manufacturers use laser marking. For example, precision scales can be applied to plastic products used in medical technology. Even after multiple cleaning cycles, these scales remain clearly legible and are highly resistant to temperature and environmental factors. Color changing and foaming enable the flexible creation of highly legible, durable, and high-contrast labels and images, e.g. Laser marking of plastic, or plastic engraving, is a process during which components are labelled or marked with the aid of a laser. 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. Challenges for Plastic Laser Marking Machine Manufacturers. Generally, the fiber laser generates a white mark on any plastic … 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. The marking process produces such … TRUMPF Group, Entire overview In carbonization, carbon-containing plastics burn or carbonize on the surface. Laser engraving plastic demands both scientific and creative approach. along with other resins for marking with variety of … Contrast is created by the color of the base material or base coating. Foaming is therefore usually used for black and dark colors. The resulting raised markings are about 20 to 40 μm high and relatively wide. Contact People, Entire overview Our plastic marking systems come in a variety of sizes … High-quality, reproducible and fully solvent-free: Joining plastics using lasers has many advantages and numerous applications. Industries, Entire overview Based on your configuration, United States might be more appropriate. 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. Online Magazine, Entire overview Especially when processing flame-retardant plastics, it is important that the material and wavelength are optimally matched to each other. 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. Color molecules can be selectively bleached out or their color changed. TRUMPF provides you with a complete solution for your specific application. Copyright © 2020 MECCO. Buttons in vehicle interiors are an example of markings achieved by layer ablation. We offer premium engraving, ADA, cast and extruded acrylic and architectural sign substrates for laser … Surfaces remain largely unaffected and smooth. The flexible laser tool applies high-contrast and permanently legible, high-resolution product markings even in difficult to access areas. 2020 Manufacturing Regulations Making a Mark on Traceability, 5 Dos and 5 Don'ts for Selecting the Marking Technology Your Product Needs, Customer Service that Speaks Directly to Your Bottom Line, 6 Ways Laser Marking Will Save You Time and Money. Lasers, Entire overview Software, Entire overview Laser marking is the most flexible way of marking plastics and yields legible, sharp and indelible images. Absorption by the macromolecular structure of plastics is usually in the ultraviolet and far infrared range. Plastics are materials that pose several challenges to many marking systems. Laser wavelength plays an important role in the marking of plastics, depending on the application. Download this checklist for the critical questions to ask when shopping for a marking equipment supplier. Plastic This section introduces a variety of information, from plastic marking/processing principles to laser features according to wavelength.
