Laser engraving machines are predominantly CO₂ laser models, which are numerical control processing equipment that utilizes infrared laser beams to engrave, emboss, hollow out, cut, mark, and trim non-metallic materials. By importing pattern drawings through computer software, the equipment completes non-contact thermal processing along the set trajectory, enabling fine engraving, multi-depth layer carving, and irregular shape cutting. They are widely used in cultural and creative processing, advertising signs, woodworking crafts, packaging boxes, clothing and leather industries, suitable for small batch production.
