塑料制品激光打标（Laser marking of plastic products） Plastic products laser marking, plastic mark marking machine, carbon dioxide laser marking machine, CO2 laser marking machine, laser marking equipment First, laser marking of plastic products 1. laser marking process for plastics Plastic is an important packing material. Plastic products on trademark, barcode and number for identification mark printing, labelling, packaging and other external contraction of hot stamping processing usually generated by, or through the surface of plastic products processing machinery such as stamping, direct, engraving, punching and forming a mark. And the use of laser marking machine in plastic surface marking is a kind of high speed machining, the surface properties of plastic products can keep the inherent, the words and numbers or icons and plastic products become a unified whole new marking technology. Plastic marking machines use laser beams to directly produce markings on plastic surfaces, including markings, codes, labels, characters, lines, numbers, and even colors, without any other processing steps. 2. laser marking equipment and materials In order to obtain a clear laser mark, you must know the following points: 1 laser marking equipment Different lasers can emit light at different wavelengths. The penetration ability of different lasers is different, and the adaptability of different lasers affects both the labeling quality and the labeling speed. Although there are many laser light sources used for marking surfaces of plastics. But sealed CO2 laser is the most widely used marking laser, followed by solid-state Nd YA G laser and diode Nd YA G laser. As a result, carbon dioxide lasers should be preferred for marking plastic products, and Nd YA G lasers can be selected if they are not required for contrast or plastic over melting. CO2 laser marking machine The selection of laser marking machine, the cost is a key factor, a carbon dioxide laser marking machine is priced at 25 thous
