Working principle The core principle of a laser marking machine is the interaction between laser and materials, mainly achieving marking through two ways: Hot working The laser beam is focused on the surface of the material, generating high temperatures (up to several thousand degrees Celsius), causing local vaporization, melting or carbonization of the material, and forming permanent marks (such as metal engraving, plastic ablation). Applicable materials: metals, ceramics, engineering plastics, epoxy resins, etc. Cold working (photochemical decomposition) By using short-wavelength lasers such as ultraviolet lasers, the molecular bonds of materials are broken through photochemical reactions, thereby changing the surface color (such as the light-colored marks on glass, films, and pharmaceutical packaging), without obvious thermal damage. Applicable materials: flexible materials, high molecular polymers, semiconductor components, etc. Main Types and Characteristics According to the type of laser light source, common laser marking machines can be classified into the following categories: Fiber laser marking machine Light source: Fiber laser (wavelength 1064nm, near-infrared light). Features: High energy density: Fast marking speed, large depth, suitable for metals and some non-metallic materials. Maintenance-free: The lifespan of fiber lasers is over 100,000 hours, and there is no need to replace consumables. Strong stability: Adaptable to industrial environments and has strong anti-interference ability. Application scenarios: Electronic components (such as chip pin coding), hardware tools, automotive parts, stainless steel products, etc. CO laser marking machine Light source: CO gas laser (wavelength 10.6μm, far-infrared light). Features: Good non-metallic compatibility: High absorption efficiency for organic materials such as wood, leather, acrylic, and paper. Wide power range: Available from 30W to 200W, suitable for materials of different thicknesses. Application scenarios: packaging industry (production date
