Different material types behave differently while progressing with laser marking plastic, and there are lots of them: polypropylene, polyethylene, polyamide, acrylic, nylon, silicone and many more. So laser marking makes a lot of sense, for plastics as well as other materials. Laser marking causes physical and chemical changes on the surface of the plastic, thus causing marks that are more permanent than standard ink printing or etching. A great diversity of plastics are being deployed especially in the automotive or medical industry. Laser marking on plastic can be obtained with either a CO 2 or a fiber laser source. 01/07/2020. This makes laser marking the preferred option for marks that need to remain legible even after several years, such as part numbers and serial numbers. Foaming works on all polymers, but also on some metals. The resulting raised markings are about 20 to 40 μm high and relatively wide. Plastic Marking with a Laser A fiber laser from Epilog is the perfect choice for marking engineered plastic parts with barcodes, serial numbers and logos. The CO 2 laser is more often used for etching or engraving on the plastic. The polymer that the plastic parts are made of dictates the methods used and also the energy input needed to laser the plastic. The quality of the marking on a plastic part is determined by the type of the selected laser etching system, the utilized marking parameters, but also by the use of special additives in the plastic mix. So marking provides a finish similar to printing designs and other surfaces that cannot be erased. along with other resins for marking with variety of different lasers like 1064 nm Nd:YAG-Laser, fiber laser and solid state lasers. To achieve an enhanced laser marking for polypropylene, the “core-shell” [email protected] (antimony-doped tin [email protected]) laser-sensitive composite was successfully designed and prepared.This laser-sensitive composite consisted of an ATO “core” with high photothermal conversion efficiency and a PI “shell” with high laser induced carbonization rate. Marking of ABS Black Plastic redENERGY G4 20W EP-Z. Advanced Laser Marking, Etching and Engraving of Stainless Steel, Some Plastic, and Ceramic Parts .

As laser marking systems become more advanced and gains importance Laser marking on plastic electronic components. Email: xintian104@xtlaser.com. ABS plastic Annealed black marking The irradiation of the laser light produces a black color on the surface of the plastic. Carbonizing on the other hand enables strong contrasts on bright surfaces. It introduces marking examples and the optimal laser markers for a variety of materials such as ABS, epoxy, and PET. Plastic marking applications are numerous in many industries, like household appliances, interior components motor parts in automotive industry, and many others. Fast, programmable, environmentally clean laser marking has established a niche in basic marking of dates and product codes, but it is capable of much more. Laser: Topics: Based on the nature of the plastic, its functional purpose and its intended use the requirements for its marking are varying. The light is diffusely reflected, and the marking on dark plastic appears bright. Laser marking of plastic, or plastic engraving, is a process during which components are labelled or marked with the aid of a laser. Color laser engraving can essentially be broken down into two subsets, that of color laser engraving on metal and color laser marking on plastic.
