A laser marking machine is a cutting-edge piece of technology that uses concentrated beams of light to engrave or mark surfaces with high precision. It is widely used in industries such as manufacturing, automotive, electronics, jewelry, and healthcare, offering unmatched accuracy and durability for marking various materials, including metals, plastics, ceramics, and glass.
How Laser Marking Machines Work
Laser marking machines operate by directing a laser beam onto a surface, creating a permanent mark without physical contact. The process works by altering the material’s properties or appearance through:
Engraving: The laser beam removes material to create a deep mark.
Annealing: Heat changes the material’s color, typically used for metals.
Foaming: Generates bubbles in the material to create a raised, lighter mark.
Coloration: Alters the material’s color for visual contrast.
Carbon Migration: Brings carbon to the surface for darker marks, often used on metals.
Types of Laser Marking Machines
Fiber Laser Marking Machine:
Best suited for marking metals and hard plastics.
