Careful calibration of the laser power to its application ensures maximized productivity without compromising product quality.
Primary Considerations Laser Power Effect, Marking Speed, And Efficiency Of Both
Marking speed and overall efficiency is controlled by certain industrial factors as laser power is set for an industry use. It is well known that faster processing speed is achieved by higher laser power. For example, a 30W laser would mark in about 15 seconds while a 60W laser could mark it in half that time depending on material characteristics.
Optimun laser power settings are also determined by material type and reflectivity. Highly reflective metals like cooper and aluminum demand higher power levels as a great deal of the laser light is reflected back. On the other hand, more matte finished metals and most plastics need lower power setting since they are less reflective to protect them from unintentional harm.
Lastly, the output is also impacted by the pulse frequency, spot size, and wavelength of the laser technology. For example, the capability to mark with greater resolution is critical for placing detail engravings and intricate patterns. Fiber lasers offer finer spot sizes, making detailed engraving possible.
