Fiber laser markers use focused laser light to mark materials by ablating, melting, vaporizing, or removing surface material. The process produces short laser pulses (9 ns to 520 ns ) and a fine diameter spot ranging from 0.002″ to 0.01″ which enables precise control of the marking process while introducing negligible heat input to surrounding material.
Fiber laser markers direct focused laser energy onto the surface of a part. The energy interacts with the material to create a permanent mark by modifying or removing a small amount of material.
Because the laser beam can be tightly focused and controlled, fiber laser markers can produce precise, high-quality marks with minimal thermal impact.
Other common names for laser marking include:
These terms describe similar processes that use laser energy to create permanent marks on material surfaces.
Fiber laser marking is a fast and clean marking technology that is increasingly replacing traditional marking methods like chemical etching or dot peen.
Key advantages include:
These characteristics make fiber laser markers well suited for modern manufacturing environments.
One of the primary drivers behind the adoption of fiber laser marking is the growing use of direct part marking for product identification and traceability.
Laser marking enables manufacturers to permanently mark components with identifying information used for tracking throughout production and the supply chain.
Industries where traceability is particularly important include:
