Gas Nozzle A gas nozzle in laser engraving is a component that directs a stream of compressed gas, such as air or nitrogen, onto the material surface during engraving. The gas nozzle helps remove debris, cool the material, and improve engraving quality by assisting in material removal and preventing heat-induced damage. Gas nozzles come in various designs, including flat, conical, or cylindrical shapes, and may incorporate features such as adjustable airflow, multiple outlets, or protective coatings to enhance performance and versatility in different engraving scenarios. |
