CO2 laser sources for organic materials
As a matter of principle, CO2 lasers are suitable for engraving and cutting organic materials. This includes, for example, wood, paper / cardboard, textiles, foams and various plastics, including acrylic and films. But even anodized aluminum and other coatings can be processed at high quality or ablated in a defined manner, respectively, with a CO2 laser. For laser processing of these materials, flatbed lasers are frequently used, since the workpieces require a larger working area. However, the disadvantage of flatbed systems compared to galvo laser systems is the much lower processing speed. This can be particularly noticeable when large numbers of very fine geometries are to be engraved. In addition, galvo lasers offer significantly greater focus tolerance, meaning that minor irregularities in the material do not influence the processing result. Thus, if the laser processing fields are smaller and the numbers of parts higher, galvo lasers offer clear advantages for organic materials as well. The fields of application are diverse, ranging from the serial marking of wooden parts for euro pallets through marking with deep engraving of plastic housing parts to the cutting of films and injection-molded parts.
