The CO 2 laser is more often used for etching or engraving on the plastic. Get information about our processes and technologies! The product surface is colored photochemically. Quando il materiale di base viene irradiato con un laser, l'effetto termico della radiazione all'interno del materiale genera delle bolle di gas. Il grafico sotto mostra il tasso di assorbimento di un laser fondamentale (1064 nm), un laser verde (532 nm) e un laser UV (355 nm) per vari materiali plastici. Laser Engraved ABS Plastic. For special applications, colorful markings on a dark base color can be achieved. The laser choice will depend on the application requirements. The radiant energy is absorbed locally by the material and converted to thermal energy which induces reactions in the target polymer substrate. Laser sensitive additives are also available as Masterbatch at AF-COLOR and can be combined with different polymers. Di conseguenza, la composizione dell'elemento stesso subisce una trasformazione chimica, determinando un viraggio dovuto alla maggiore intensità del pigmento. For plastics Laser Marking, the mechanism is to irradiate the polymer with a high-energy radiation source, e.g., Ytterbium fiber laser.

Laser Marking Plastic | Accubeam Molded plastic parts have become ubiquitous components of industrial equipment, medical devices, aerospace & aviation components, vehicle & marine parts and common household appliances. Le molecole si condensano e il colore cambia diventando più scuro. Quando il materiale di base assorbe l'energia del laser, l'effetto termico aumenta la densità molecolare. Laser marking of plastic, or plastic engraving, is a process during which components are labelled or marked with the aid of a laser. Rimuovere/incidere lo strato superficiale con un laser. UV Laser Marking Machine : Well-suited for marking heat-sensitive materials, including a number of plastics, from HDPE and silicone to polycarbonate and polyethylene. For plastics marking, the source is most typically a solid-state (vanadate) laser, since these provide the short pulse duration that usually delivers the most pronounced color or contrast change in the plastic without any thermal damage to the material. In the case of plastics, the process is characterized by a fast marking speed and low cycle times. Irradiation from the laser light results in a black / highly visible white color on the surface of the plastic. Il tasso di assorbimento per la poliimmide invece varia a seconda della lunghezza d'onda: è molto alto per laser UV, mente è basso per un laser fondamentale.
