This page shows some applications and information of laser processing. Laser marking is a non-contact optical process in which the plastic has to absorb the laser beam. Peel the paint or printing on the target surface to bring out the contrast with the colour of the base material. 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. Laser Marking Plastics? Consequently, the composition of the element itself changes chemically, resulting in colour development due to the increased intensity of the pigment. Scanning irradiates a target with a single laser light, and marking is performed in a stroke-like motion. Lasers can be used for a variety of marking methods including surface melting and scorching, plating and paint peeling, oxidisation, and discolouration. When the base material absorbs the laser energy, the thermal effect increases the molecular density. Laser engraving plastic demands both scientific and creative approach. Laser marking: The laser beam acts by decoloring the heated surface (clear marking on dark plastic or grey or black marking on clear material). The laser choice will depend on the application requirements. These scanning mirrors are called galvano mirrors, and a system that uses one or more of these mirrors is called a “galvano scanner” or “galvano mirror scanning system”.

Laser Cut Nylon Services Nylon is a man-made synthetic fiber that is known for its elasticity and strength. Laser marking is used for marking logos, product names, serial numbers, model numbers, and other information onto a product by irradiating the target with a laser light to melt, scorch, peel, oxidise, cut, or discolour the surface. More specifically, a laser light emitted from an oscillator is captured (scanned) by the scanning mirror and applied to the surface of the target for marking. Depending on the material structure and size, different laser sources (e. g. fiber lasers) or laser machines (e. g. galvo lasers) can be used to further increase the speed. In the White Paper you will learn that the quality of the marking is determined by the type of the selected laser etching system, the utilized marking parameters, but also by the selection of special additives in the plastic mix. The laser works with a maximum pulse rate, but low energy per pulse. When the base material is irradiated with a laser, gas bubbles are generated inside the material due to the thermal effect of the radiation. Irradiation from the laser light results in a highly visible white colour on the surface of the plastic. Laser-based colouration can be divided into four main principles. Laser markers can be roughly divided into two types: masking laser markers and scanning laser markers. Laser markings on plastic surfaces are always smudge and abrasion resistant. 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. With laser marking, however, there is no need to worry that marked content will disappear over time. Selecting the best marking method ensures damage-free marking regardless of the target material. Color laser engraving can essentially be broken down into two subsets, that of color laser engraving on metal and color laser marking on plastic. The most common processes of laser marking on plastic are carbonization, color change, foaming and engraving. Marking visibility and durability .
